Altair BASIC was the start of the Microsoft BASIC product range, and it interpreted the BASIC programming language. The Altair 8800 was, to its creators, a surprise hit. It was functionally similar to the Altair 8800 but it was a commercial grade system with a wide selection of peripherals and development software. The system came with a "1024 word" memory board populated with 256 bytes. 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. The Altair 8800 from Micro Instrumentation Telemetry Systems (MITS) of Albuquerque, NM, is considered by many to be the first "personal computer" - a computer that is easily affordable and obtainable. It had a 14-digit display, memory, and square root function. The first 50 IMSAI computers shipped in December 1975. The MITS 1440 calculator was featured in the July 1973 issues of Radio-Electronics. 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. The MITS Altair 8800 was the primary commercially successful personal pc. 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. Many home computers of the day were available as kits. Altair 8800. The kit sold for $200 and the assembled version was $250. [9] The MITS 816 calculator kit used the chipset and was featured on the November 1971 cover of Popular Electronics.

Programming the Altair 8800 in its native capacity was horrendously tedious. He was impressed with Don Lancaster's TV Typewriter (Radio Electronics, September 1973) article and wanted computer projects for Popular Electronics. 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. TIL how to program an Altair 8800, and subsequently why Bill Gates' Altair basic was such a game changer. The 97. "[20] Ed Roberts had experience in buying OEM quantities of calculator chips and he was able to negotiate a $75 price (about $350 in 2014 dollars) for the 8080 microprocessor chips. 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. The S-100 bus was eventually acknowledged by the professional computer community and adopted as the IEEE-696 computer bus standard. Copyright catalogs at the Library of Congress. Free shipping. 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 The Altair 8800 simulator is part of the SIMH family of simulators currently at version 3.8-1.
