Not too long ago, the thought of an honest, full-blown, high-quality computer that sells for less than $500 would have been considered a mere pipe dream. Everyone knows that computers are monstrous, box-shaped machines that sell for 10's and 100's of thousands of dollars. Pipe dream or not, MITS, the quality engineering company that pioneered the calcu lator market, has made the Altair 8800 a reality. It is the realization of that day when computers arc accessible to almost anyone who wants one. I The heart (and the secret) of the M ITS Altair 8800 is the Intel 8080 processor chip. Thanks to rapid advances in integrated circuit technology, this one IC chip can now do 3 what once took thousands of electronic components (including 100's of IC's) and miles of wire. Make no mistake about it. The M ITS Altair 8800 is a lot of brain power. Its parallel, 8-bit processor uses a 16-bit address. It has 78 basic machine instructions with variances up to 200 instructions. -

This year's real winner looks like being the PACE chip, from National Semiconductor. These things are oot easy to make. The difficulty of making them is lIflormoosly increased as they get bigger ••nd a 16 bit CPu is awful big. The $lory starts with a few enthusia$ls. a blackboard and a whole crew who doubted it could be made at all. Moby chip, as it was known, was oot a project for the faint hearted. The crooked tines on the blackboard soon became straight and well defined. Very. This is the beginning of the marks which OPtically define the position of every tiny facet of the chip to be. The precision of the whole process starts here, and hera also is the place where chips can be designed not to work - tNery line is checked and rechecked and ... Sometimes a particular person can make things when others can't. There Is the tale of the big manufacturer Now the magic begins. It starts with. sinlJle Cl'VSUI which was licensing a company in another country to of pure silicon. -

The Computer History Simulation Project
The Computer History Simulation Project The Computer History Simulation Project The Computer History Simulation Project is a loose Internet-based collective of people interested in restoring historically significant computer hardware and software systems by simulation. The goal of the project is to create highly portable system simulators and to publish them as freeware on the Internet, with freely available copies of significant or representative software. Simulators SIMH is a highly portable, multi-system simulator. ● Download the latest sources for SIMH (V3.5-1 updated 15-Oct-2005 - see change log). ● Download a zip file containing Windows executables for all the SIMH simulators. The VAX and PDP-11 are compiled without Ethernet support. Versions with Ethernet support are available here. If you download the executables, you should download the source archive as well, as it contains the documentation and other supporting files. ● If your host system is Alpha/VMS, and you want Ethernet support, you need to download the VMS Pcap library and execlet here. SIMH implements simulators for: ● Data General Nova, Eclipse ● Digital Equipment Corporation PDP-1, PDP-4, PDP-7, PDP-8, PDP-9, PDP-10, PDP-11, PDP- 15, VAX ● GRI Corporation GRI-909 ● IBM 1401, 1620, 1130, System 3 ● Interdata (Perkin-Elmer) 16b and 32b systems ● Hewlett-Packard 2116, 2100, 21MX ● Honeywell H316/H516 ● MITS Altair 8800, with both 8080 and Z80 ● Royal-Mcbee LGP-30, LGP-21 ● Scientific Data Systems SDS 940 Also available is a collection of tools for manipulating simulator file formats and for cross- assembling code for the PDP-1, PDP-7, PDP-8, and PDP-11. -
The Tarbell Cassette Interface
THE TARBELL CASSETTE INTERFACE Plugs directly into ALTAI R * 8800 or IMSAI 8080 Computer. Serial-Parallel and Parallel-Serial Conversion performed on board. It's fast - Up to 540 bytes per second (2200 bits per inch) with high-quality cassette recorder. 187 bytes per second (800 bits per inch) suggested s.tandard with medium quality ($39.95) recorder. 27 bytes per second (with modification) for Kansas City format. 1000 bytes per second @ 10 inches per second with PHI-DECK. Encoding method - Phase encoded self-clocking method requires only one channel, and withstands large amounts of wow and flutter. Has been used in the computer industry for many years. Can also be used to generate and detect Kansas City format tapes \~. ith small mod ification. Will work with most audio cassette recorders. Has been used with reel-reel tape recorders. Can easily be adapted to automatically (software) controlled digital cassette units. The J. C. Penny #6536 is presently being recommended ($39.95). Suggested tape is Scotch Low-Noise, High-Density audio tape. The device code (address) to which the interface responds is selectable in increments of 4 by an on- board dip-switch. '. Four extra status lines are available to read external conditions. Four extra control lines are available, which may be used to drive relays for extra cassette units, start stop control, or controlled cassette drives, such as the PHI-DECK. Two spare IC slots are provided on the board to do your own thing. Software provided includes input/output driver routines, bootstrap, read-only memory program, and a ' BASIC program for saving and loading data. -

Enter the hero: Ted Hoff • Ph.D. Stanford University: Electrical Engineering – Semiconductor memories; several patents • Intel's 12th employee: hired to dream up applications for Intel's chips • Noyce wanted Intel to do memory chips only! • 1969: ETI, a Japanese calculator company -- wants a chip for a series of calculators The Microprocessor • ETI calculator would cost as much as a mini • "Why build a special purpose device when a general purpose device would be superior?" • Hoff proposed a new design loosely based on PDP-8: the Japanese weren't interested! • October 1969, Japanese engineers visit Intel to review the project, and agree to use the I 4004 for their calculator. -

ALTAIR 8800 / IMSAI 8080 Replacement CPU Project Josh Bensadon June 5, 2014 Toronto Canada I cannot thank everyone by name or else I may forget someone, but you know who you are and thank you for your help and friendship. Special Thanks to everyone at the N8VEM group for their endless help and wonderful ideas that broadened the scope of this project. Extra Special Thanks to Andrew Lynch for his hard work to build and distribute the boards in the N8VEM realm. Only after doing similar work did I realize how much labour is involved. Also Extra Special Thanks to John Monahan for all his hard work building www.S-100computers.com Introduction Thank you for your interest and participation in this project. It drew on several skills and took many hours to bring it to this point. As an electronics hobbyist, I enjoy the roots of my interest as formed by endless hours of studying Popular Electronics and Radio Electronics magazines from the 70’s and 80’s. Recently, I’ve been taking a larger interest in the history of personal computers. As such, I would like to include a short history of this project board.
