The Altair 8800 is a microcomputer designed in 1974 by MITS and based on the Intel 8080 CPU. Altair was the first home computer kit (well, first popular one anyway). Altair 8800 System (1975) by . But working vintage Altairs are rare and therefore expensive, easily costing $1500-$2500 if available at all. In 1974, Art Salsberg became editor of Popular Electronics. Some salesmen said that MITS was getting cosmetic rejects or otherwise inferior chips. In fact, a fully loaded Altair 8800 was a usable and functional computer well into the mid-80’s. The calculator was successful and was followed by several improved models. Roberts focused on delivering the computer; all of the options would wait until they could keep pace with the orders. Posted by 3 years ago. Created with the aid of Ed Roberts in 1974, it was purchased by means of the lots through mail order, proving there has been a big demand for computer systems out of doors universities and big groups. Pre-Owned. 1. The Front Panel of the Altair 8800 exists of 16 address LEDs, 8 data LEDs, 8+4 status LEDs. [citation needed] Another oddity was that the system included two unidirectional 8-bit data buses, when the normal practice was for a single bidirectional bus (this oddity did, however, allow a later expansion of the S-100 standard to 16 bits bidirectional by using both 8-bit buses in parallel). The "lid" was shaped like a C, forming the top, left, and right sides of the box. The Altair 8800 has a special input port, 0xFF, which is the current position of the sense switch. [19] At that time, Intel's main business was selling memory chips by the thousands to computer companies. Copyright catalogs at the Library of Congress. Programming required the toggling of the switches to positions corresponding to the desired 8080 microprocessor instruction or opcode in binary, then used the 'DEPOSIT NEXT' switch to load that instruction into the next address of the machine's memory. The Altair 8800 front panel. Adrian. Object Program Program Source Program System Program User Program Word nnnnB nnnnD nnnnO nnnnQ nnnnH DESCRIPTION A 16-bitnumber assigned to a memory location corresponding to its sequen tial position. The computer bus designed for the Altair was to become a Teach and reinfor… [10] Forrest Mims wrote the assembly manual for this kit and many others over the next several years. Their company, then called "Micro-Soft," survived. Roberts got to work on building a replacement. Popular Electronics featured the MITS Altair 8800 microcomputer kit in January 1975. Despite looking nothing like what we would today consider to be a computer, it sold thousands of units … Ed Roberts was busy finishing the design and left the naming of the computer to the editors of Popular Electronics. It was Microsoft's first product (as Micro-Soft), distributed by MITS under a contract. $39.99. Figure 2.1: Altair 8800. The Altair 8800 Clone can be used for a number of excellent demonstrations for topics including the history of computing, intro to operating systems, microprocessor basics, number systems, etc. )[14], One of the editors, Les Solomon, knew MITS was working on an Intel 8080 based computer project and thought Roberts could provide the project for the always popular January issue. The Altair-Duino is based on an Altair 8800 emulator project published on hackster.io by David Hansel using the Arduino Due and Arduino Mega 2560, which you can, of course, replicate from scratch. As I mentioned, toggle switches are connected directly to the raw, unbuffered 8080 data bus. An assembled and tested Altair-Duino available in Standard and Pro models. In 1970, electronic calculators were not seen outside of a laboratory, but by 1974 they were a common household item. "That figure had a nice ring to it," recalled Intel's Dave House in 1984. of the ALTAIR 8800. A distinguishing feature of the Altair and IMSAI computers is their primary user interface - the front panel covered in LEDs and switches. $199.99. Whether used for personal or educational purposes, the Altair Clone is a great way to relive this important period in computing history and learn core computer science principles at the same time! The computer has 78 machine language instructions and is capable of performing several important operations not normally available with conventional mini computers. If you combine the Altair 8800 with a standard ASCII video terminal and keyboard, and add a disk drive, it became a very powerful and useful computer system (especially for 1975!) Dorf, Richard C., ed. Gates soon joined Allen and formed Microsoft, then spelled "Micro-Soft". The video library below is full of hands-on demonstrations and tutorials. Despite looking nothing like what we would today consider to be a computer, it sold thousands of units … [16] The January 1975 issues appeared on newsstands a week before Christmas of 1974 and the kit was officially (if not yet practically) available for sale.[14][15][13]. The MITS 1440 calculator was featured in the July 1973 issues of Radio-Electronics. Altair BASIC was the start of the Microsoft BASIC product range. Their company, then called "Micro-Soft," survived. Programming the Altair 8800 in its native capacity was horrendously tedious. As I mentioned, toggle switches are connected directly to the raw, unbuffered 8080 data bus. Buy It … In fact, a fully loaded Altair 8800 was a usable and functional computer well into the mid-80’s. The MITS Altair 8800 was the primary commercially successful personal pc. The smallest unit of information which can be represented. They would later develop a popular video display board that would plug directly into the Altair. If you can write even the simplest of programs on an Altair, then you have a level of insight into how computers really work that puts you in an elite echelon. Altair: The Altair was the world's first personal computer ( PC ) to attract a substantial number of users. In addition to calculators, MITS made a line of test equipment kits. It helps that the Altair 8800 was also sold as a kit so you had to know what components went into it. You can still find Altairs in museums, and some lucky individuals still have their machines. For a decade, colleges had required science and engineering majors to take a course in computer programming, typically using the FORTRAN or BASIC languages. MITS and many other companies were devastated by this, and Roberts struggled to reduce his quarter-million-dollar debt. Altair 8800 Programming Is As Easy As Computer T-shirt Large Used. The Altair 8800, was first featured ... Bill Gates and Paul Allen saw an opportunity and wrote Altair BASIC, a true programming language. Though the article's description of the programming task is essentially correct (flipping switches to input the binary opcodes), the description of the output isn't quite spot-on. He thought the Intel 4004 and Intel 8008 were not powerful enough (in fact several microcomputers based on Intel chips were already on the market: the Canadian company Microsystems International's CPS-1 built-in 1972 used a MIL MF7114 chip modeled on the 4004, the Micral marketed in January 1973 by the French company R2E and the MCM/70 marketed in 1974 by the Canadian company Micro Computer Machines); the National Semiconductor IMP-8 and IMP-16 required external hardware; the Motorola 6800 was still in development. for additional videos. So during the construction of the second model, he decided to build most of the machine on removable cards, reducing the motherboard to nothing more than an interconnect between the cards, a backplane. The Altair 8800 Clone is a full size, fully functional replica of the computer that started a revolution – the Altair 8800. MITS claimed to have delivered 2,500 Altair 8800s by the end of May. This is it folks, the original MITS Altair 8800 (approx serial number 3000). Programs were hand compiled, meaning you needed to reference the Intel 8080 command set and determine the flow and branching of the program on your own. The The Altair Experience ... MITS Programming Package II (Assembly language development environment before floppy drives) CP/M for the Altair (CP/M 1.4, CP/M 2.2 and CP/M 3.0) Altair Minidisk Software (BASIC, DOS and CP/M 2.2) Front Panel Programs; Music on the Altair ; ROMs (DBL, MBL, TURMON, 8K BASIC, Extended BASIC, VTL-2) 8080 CPU Tests; … People literally pulled what we experience today as an “Apple Launch” type of action where they parked and camped in front of MITS to await the manufacture of their new computer. It has 16 address switches, of which 8 can also be used as data entry switches and the other 8 as 'sense' switches for giving user input to a running program. No particular level of thought went into the design, which led to such disasters as shorting from various power lines of differing voltages being located next to each other. He called the company and reached a private home, where no one had heard of anything like BASIC. In January 1972, Popular Electronics merged with another Ziff-Davis magazine, Electronics World. The IMSAI advantage was short lived because MITS had recognized these shortcomings and developed the Altair 8800B which was introduced in June 1976. They installed a wave soldering machine and an assembly line at the new location. Watch; POPULAR ELECTRONICS ALTAIR 8800 February 1975 Part 2 COMPUTER Kit Edward Roberts . [30] MITS had under 20 employees in January but had grown to 90 by October 1975.[31]. Created by Ed Roberts in 1974, it was purchased by the thousands … The advantage of the Altair-Duino is that it includes all the components and a custom printed circuit board. The BASIC language was announced in July 1975 and it required one or two 4096 word memory boards and an interface board. [31] The delay in shipping optional boards and the problems with the 4K memory board created an opportunity for outside suppliers. The Altair 8800 was, to its creators, a surprise hit. The finished Altair computer had a completely different circuit board layout than the prototype shown in the magazine. It must have been really expensive – note the ‘Save Over $1000’ line. 1 Answer. There was no monitor. [34] The IMSAI 8080 computer improved on the original Altair design in several areas. But they're rare. A deal on power supplies led to the use of +8V and +18V,[citation needed] which had to be locally regulated on the cards to TTL (+5V) or RS-232 (+12V) standard voltage levels. of the ALTAIR 8800. The engineering handbook. Computer Programming help. Another problem facing Roberts was that the parts needed to make a truly useful computer weren't available, or wouldn't be designed in time for the January launch date. They figured they had 30 days before someone else beat them to the punch, and once they had a version working on the simulator, Allen flew to Albuquerque to deliver the program, Altair BASIC (aka MITS 4K BASIC), on a paper tape. MITS Altair Programming Tutorial By Mihai Pruna mihaipruna.com I always wanted to learn to program a computer in Machine Code (just 1s and 0s, the true language of computers). If we want to read the input from the sense switch, the input buffer must be switched off. TIL how to program an Altair 8800, and subsequently why Bill Gates' Altair basic was such a game changer. Monte Davidoff contributed maths routines, including the floating-point routines for Altair 4K BASIC. "Besides, it was a computer, and they usually cost thousands of dollars, so we felt it was a reasonable price. The MITS motherboard consisted of 4 slots segments that had to be connected together with 100 wires. Their advertisement in the July 1975 issue of Popular Electronics promised interface and PROM boards in addition to the 4K memory board. FAST 'N FREE. While serving at the Air Force Weapons Laboratory at Kirtland Air Force Base, Ed Roberts and Forrest M. Mims III decided to use their electronics background to produce small kits for model rocket hobbyists. (Fun video compilation) Other. The Altair 8800 front panel. The system came with a "1024 word" (1024 byte) memory board populated with 256 bytes. Popular Electronics featured the MITS Altair 8800 microcomputer kit in January 1975. Description *Any coupon codes will not work for assembled kits, they are already discounted. Free shipping. They had to hire extra people just to answer the phones. [9] The MITS 816 calculator kit used the chipset and was featured on the November 1971 cover of Popular Electronics. It must have been really expensive – note the ‘Save Over $1000’ line. In 1972 and 1973, some of the best construction projects appeared in Radio-Electronics. If you're even remotely interested in computers on the low level, and can handle your mind melting from pure nerdy goodness then you absolutely need to check out these videos the Altair 8800. Home Details Who Needs One? The S-100 bus was eventually acknowledged by the professional computer community and adopted as the IEEE-696 computer bus standard. Bill continued programming and started little business ventures until January 1975 when this magazine appeared on the stands: On the cover is an Altair 8800 computer. A distinguishing feature of the Altair and IMSAI computers is their primary user interface - the front panel covered in LEDs and switches. The first time it was run, it displayed "READY"[37] then Allen typed "PRINT 2+2" and it immediately printed the correct answer: "4". Unlike a real Altair 8800 it features several enhancements: Choice of processor (8080 CPU, Z80 CPU or 8086 CPU) Optional banked memory (16 banks with 64 Kbyte) MMU supporting ROM and memory mapped I/O MITS had no competition in the US for the first half of 1975. After reading this manual, even a novice will be able to load a program into the ALTAIR 8800. [27][28] This meant there was a sizable customer base who knew about computers. Altair BASIC was very expensive at $500, but only $75 when purchased with an Altair computer, an interface board, and 8K of memory. They needed to sell additional memory boards, I/O boards and other options to make a profit. The Altair is widely recognized as the spark that ignited the microcomputer revolution as the first commercially successful personal computer. 8080 altair-8800 application-program front-panel. Unlike a real Altair 8800 it features several enhancements: Choice of processor (8080 CPU, Z80 CPU or 8086 CPU) Optional banked memory (16 banks with 64 Kbyte) MMU supporting ROM and memory mapped I/O [23][24] Customers would ask Intel why their Intellec-8 was so expensive when that Altair was only $400. Electronics hobbyists were moving on to digital projects such as digital voltmeters and frequency counters. The typical MITS product had a generic name like the "Model 1440 Calculator" or the "Model 1600 Digital Voltmeter". Created with the aid of Ed Roberts in 1974, it was purchased by means of the lots through mail order, proving there has been a big demand for computer systems out of doors universities and big groups. Recently I started reading a biography of Bill Gates (ISBN-10: 0385420757), which starts in the early days of widely available computing. The computer cost $439 for a kit. Close. [25] The "cosmetic defect" rumor has appeared in many accounts over the years although both MITS and Intel issued written denials in 1975.[26]. When the 8080 was introduced in April 1974, Intel set the single unit price at $360 (About $1,700 in 2014 dollars). ~ Emulator of Altair 8800 Computer In 1999, I (Rich Cini) downloaded a copy of a MITS Altair emulator program written for the Windows platform by Claus Giloi. The change in editorial staff upset many of their authors, and they started writing for a competing magazine, Radio-Electronics. The BASIC language was announced in July 1975 and it required one or two 4096 word memory boards and an interface board. [15], Ed Roberts and his head engineer, Bill Yates, finished the first prototype in October 1974 and shipped it to Popular Electronics in New York via the Railway Express Agency. Unlike a real Altair 8800 it features several enhancements: Choice of processor (8080 CPU, Z80 CPU or 8086 CPU) Optional banked memory (16 banks with 64 Kbyte) MMU supporting ROM and memory mapped I/O; … Altair 8800 Computer with 8-inch floppy disk system. These included an IC tester, a waveform generator, a digital voltmeter, and several other instruments. The front panel switches were used to load in the program. This calculator kit sold for $175 ($275 assembled). Programming Languages; Office Applications; Games and Tools; Related Sites; Frequently Asked Questions; Introduction. When readers got the January issue of Popular Electronics, MITS was flooded with inquiries and orders. Although initially overwhelming, there is a logical pattern to the designs which you’ll soon come to understand and appreciate. Calculators and video games like Pong introduced computer power to the general public. In the October 1975 Popular Electronics, a small advertisement announced the IMSAI 8080 computer. In 1972, Texas Instruments developed its own calculator chip and started selling complete calculators at less than half the price of other commercial models. It ran on the MITS Altair 8800 and subsequent S-100 bus computers. Altair 8800.

One explanation of the Altair name, which editor Les Solomon later told the audience at the first Altair Computer Convention (March 1976), is that the name was inspired by Les's 12-year-old daughter, Lauren. work through the history of the Altair 8800 computer. Ed Roberts optimistically told his banker that he could sell 800 computers, while in reality they needed to sell 200 over the next year just to break even. TIL how to program an Altair 8800, and subsequently why Bill Gates' Altair basic was such a game changer. The simplicity and abundant documentation of the Altair makes it an appealing system for learning assembly programming. As payment for each manual he often accepted a copy of the kit. Notwithstanding the language's use on several minicomputers, it was the introduction of the MITS Altair 8800 microcomputer in 1975 that provided BASIC a path to universality. The Altair 8800 was, to its creators, a surprise hit. As Mims and Cagle were losing interest in the kit business, Roberts bought his partners out, then began developing a calculator kit. Many core computer science principles can be learned more effectively and in a more interesting manner with a hands-on lab series that centers around the Altair Clone. But they're rare. [1] Interest grew quickly after it was featured on the cover of the January 1975 issue of Popular Electronics[2] and was sold by mail order through advertisements there, in Radio-Electronics, and in other hobbyist magazines. 7 x 17 x 17.5 in. The Altair 8800 simulator is part of the SIMH family of simulators currently at version 3.8-1.

[33] His company was Processor Technology, one of the most successful Altair compatible board suppliers. Claus, a programmer working for Microsoft, wrote a 16-bit Windows-based "emulator" for the Altair and IMSAI 8080-based computers as a desktop toy more than a usable emulation. A number of Altair programs are included and can easily be loaded into the emulator, including Pong, Altair 4K BASIC (the first Microsoft product), Altair extended BASIC, MITS Programming System II (Due only), Altair Time Sharing BASIC (allows multiple users to use BASIC at the same time). After the Altair 8800 was announced, the waiting list was very long. The only output from the programs was the patterns of lights on the panel. The MITS Altair 8800 was the first commercially successful personal computer. He then looked for a cheap source of connectors, and came across a supply of 100-pin edge connectors. Altair BASIC was the start of the Microsoft BASIC product range. This step was repeated until all the opcodes of a presumably complete and correct program were in place. They were evaluating a computer trainer project by Jerry Ogden when the Mark-8 8008-based computer by Jonathan Titus appeared on the July 1974 cover of Radio-Electronics. An enterprising Altair owner, Robert Marsh, designed a 4K static memory that was plug-in compatible with the Altair 8800 and sold for $255. The front panel, which was inspired by the Data General Nova minicomputer, included a large number of toggle switches to feed binary data directly into the memory of the machine, and a number of red LEDs to read those values back out.[36]. Bill continued programming and started little business ventures until January 1975 when this magazine appeared on the stands: On the cover is an Altair 8800 computer. Under $500, Altair became the leading "homebrew" computer, inspiring Bill Gates and Paul Allen to write a BASIC interpreter program. The Altair Partner Alliance (APA) delivers broader access to an extended range of software solutions, using your existing Altair Units at no additional cost. The Altair shipped in a two-piece case. McVeigh suggested "Altair", the twelfth brightest star in the sky. A number of Altair programs are included and can easily be loaded into the emulator, including Pong, Altair 4K BASIC (the first Microsoft product), Altair extended BASIC, MITS Programming System II (Due only), Altair Time Sharing BASIC (allows multiple users to use BASIC at the same time). It is a great way to

In July 1975, Intel sent a letter to its sales force stating that the MITS Altair 8800 computer used standard Intel 8080 parts. Initially the programming the Altair was an extremely tedious process, as a keyboard wasn't provided. For a long time I have thought it would be cool to have an Altair 8800 computer to play around with. Solomon already had a number of pictures of the machine and the article was based on them. Altair BASIC is a discontinued interpreter for the BASIC programming language that ran on the MITS Altair 8800 and subsequent S-100 bus computers. If you combine the Altair 8800 with a standard ASCII video terminal and keyboard, and add a disk drive, it became a very powerful and useful computer system (especially for 1975!) [21][22], Intel made the Intellec-8 Microprocessor Development System that typically sold for a very profitable $10,000. CRC Press, 2004. You could run thousands of CP/M software titles (CP/M was the de facto standard operating system before MS-DOS.) The only options were to build your own system from plans and designs published or sold in … The sales force should sell the Intellec system based on its merits and that no one should make derogatory comments about valued customers like MITS. Don Lancaster did an ASCII keyboard for Popular Electronics in April 1974. After reading this manual, even a novice will be able to load a program into the ALTAIR 8800. "She said why don't you call it Altair – that's where the Enterprise is going tonight. [11] MITS later developed a programmer unit that would connect to the 816 or 1440 calculator and allow programs of up to 256 steps.[12]. MITS did not. Figure 2.1, courtesy of Wikimedia Commons, shows an Altair 8800. MITS Price List, Popular Electronics, August 1975.[32]. When it appeared on the cover of the January 1975 issue of Popular Electronics , the Altair 8800 ignited the (still accelerating) personal computer boom. Altair BASIC was the start of the Microsoft BASIC product range, and it interpreted the BASIC programming language. The Altair 8800 is controlled through a serial port on the back, no screen or keyboard plug, so you need a separate terminal. Compile, link and run a FORTRAN program CP/M 2.2 on the Altair – Introduction Booting and running a commercially available distribution of CP/M 2.2 from 1980 on an Altair 8800 Computer CP/M 2.2 Programming Edit, assemble and run a program under CP/M 2.2 as demonstrated on an Altair 8800 Computer Changing CP/M's RAM Size Relevance. The Altair had enough power to be actually useful, and was designed as an expandable system that opened it up to all sorts of applications. Electronic Arrays had just announced a set of six large scale integrated (LSI) circuit chips that would make a four-function calculator. For a long time I have thought it would be cool to have an Altair 8800 computer to play around with. The very first Altair users would actually load code via the front panel switches, one byte at a time. Archived . Guaranteed by Sat, Dec. 19. The ad noted that all boards were "plug compatible" with the Altair 8800. (Popular Electronics gave Jerry Ogden a column, Computer Bits, starting in June 1975. In 1969, Roberts and Mims, along with Stan Cagle and Robert Zaller, founded Micro Instrumentation and Telemetry Systems (MITS) in Roberts' garage in Albuquerque, New Mexico, and started selling radio transmitters and instruments for model rockets. The first 50 IMSAI computers shipped in December 1975. A consulting company in San Leandro, California, IMS Associates Inc., wanted to purchase several Altair computers but the long delivery time convinced them that they should build their own computers. [Josh Bensadon] has an Altair 8800, and became intrigued by its bootloader. Altair had nothing to do with Intel, other than making the 8080 a popular CPU, increasing Intel sales. How is the Altair 8800 related to the computer giants Intel and Microsoft? Feel free to contact us with your suggestions

The main breadboard was also probably upgraded as it is copyrighted 1977. The backplane and power supply were mounted on a base plate, along with the front and rear of the box. After you hand compiled your program, you needed to set a bunch of switches to memory addresses and the 8-bit … [6] The computer bus designed for the Altair was to become a de facto standard in the form of the S-100 bus, and the first programming language for the machine was Microsoft's founding product, Altair BASIC.[7][8]. Another explanation is that the Altair was originally going to be named the PE-8 (Popular Electronics 8-bit), but Les Solomon thought this name to be rather dull, so Les, Alexander Burawa (associate editor), and John McVeigh (technical editor) decided that: "It's a stellar event, so let's name it after a star." The Altair 8800 is a microcomputer designed in 1974 by MITS and based on the Intel 8080 CPU. TIL how to program an Altair 8800, and subsequently why Bill Gates' Altair basic was such a game changer.

Josh Bensadon loads Bill Gates' and Paul Allen's BASIC to the Altair 8800 on December 6th 2014 in Toronto at the TPUG World of Commodore Show [15][18], Ed Roberts had designed and manufactured programmable calculators and was familiar with the microprocessors available in 1974. Programming the Altair 8800 in its native capacity was horrendously tedious. [3][4] The Altair is widely recognized as the spark that ignited the microcomputer revolution[5] as the first commercially successful personal computer. Nevertheless, many were sold in this form. The Altair-Duino is based on an Altair 8800 emulator project published on hackster.io by David Hansel using the Arduino Due and Arduino Mega 2560, which you can, of course, replicate from scratch. But working vintage Altairs are rare and therefore expensive, easily costing $1500-$2500 if available at all. (A bit may be in one of two states, represented by the binary digits 0 or 1). Altair BASIC is a discontinued interpreter for the BASIC programming language that ran on the MITS Altair 8800 and subsequent S-100 bus computers. When they called Roberts to follow up on the letter he expressed his interest, and the two started work on their BASIC interpreter using a self-made simulator for the 8080 on a PDP-10 minicomputer. The letter was reprinted in the August 1975 issue of MITS Computer Notes. The Altair 8800 has a special input port, 0xFF, which is the current position of the sense switch.
