MITS Altair 8800 Complete History of the MITS Altair 8800.
The MITS Altair 8800 was the first customizable microcomputer. It can be thought of as the predecessor to the Arduino and Raspberry Pi microcomputers. The Altair 8800s initial team of creators consisted almost entirely of United States Air Force veterans, many of whom were still serving when MITS was founded. Intel 8080 I/O Supports dedicated input and output operations 256 addressable ports Utilize address and data lines, but adds a pin to designate memory or I/O operation Altair implementation used primarily memory-mapping Exception is 8 sense switches and LEDs on front panel Designed to use Support Chips.

Qamp;A for vintage-computer hobbyists interested in restoring, preserving, and using the classic computer and gaming systems of yesteryear. The build unofficially began with an Intel 8080 emulator written for an Arduino. The 8080 is the brains of the Altair, and while emulators are cool, they dont have the nerd cred of a panel of.

All of the circuitry - the CPU and memory, are on cards which plug into the expansion slots, which MITS called the quot;Altair Busquot;. This became a very easy and popular method of designing computers, and numerous other systems from competing manufacturers were released utilizing the same Altair Bus - the IMSAI 8080 was the first - the first. On an Apple II, every slot had a corresponding address range where ROM routines could be expected to be. When the II boots, it checks every slot, from 7 downwards, for a ROM and tries to boot from it. That#39;s how disk booting works on the II. This is how the II can tell there is an 80-column card on slot 3 and a printer card on slot 1. 4K Static Ram Board 1.2M PDF 4K Dynamic Ram Board 1.2M PDF 88-4 Parallel I/O Bpard 1.8M PDF 88-ACR Audio Cassette Interface 2.3M PDF 88-VI Vector Inerrupt Real Time Clock 1.9M PDF Cards currently installed in my Altair NorthStar Micro Disk System 1.1M PDF NorthStar Micro Disk System errata 200k PDF Central Data 64K dynamic RAM.

Like the old Altair S-100 bus, cards can be interchanged between them, and new cards can be designed that will work with both. 8080 CPU Front Panel card. The 8080 itself is at the top, front and center for all to see. Left of it is the 8224 clock, reset, and ready generator. To the right of the 8080 is the switchmode power supply, using the. It means the Intel 8080 CPU is emulated, as is some of the basic I/O disk drives, serial ports, etc. but everything else is REAL Altair machine code and CP/M that was created more than 40 years ago. Original Altair 8800. Dimensions: 17quot; x 7quot; x 18quot;. Weight: depends on cards loaded, but generally around 65 lbs. RAM: 64KB maximum.
Altair 8800micro Briel Computers.
MITS and Altair history. First offered to the public in January 1975 by MITS in a Popular Electronics front-page article, this is an image of an Altair 8800 computer. It was designed by MITS founder and president Ed Roberts in 1974. It initially contained several major components: a 4-slot motherboard with bus connectors of 100 pins each, soon.
Altair BASIC via 8080 emulation JeeLabs.
There is a nice and clean emulation of the Intel 8080 microcomputer chip available - and as always it#x27;s on GitHub. We can take this code and pair it with Altair BASIC. It#x27;s famous because it was Microsoft#x27;s first product you may have heard of that company somewhere. The particular version we#x27;ll use is the smallest one, which fits in. The current code is fairly slow. A couple of times slower than the original Altair 8800. There is room for optimization or even a faster MCU. Running. The code currently loads the file quot;; from the SD card and places it at 0xff00 in memory. This is a standard disk loader ROM using the 88-DCDD Altair disk drive system.
DigiBarn Systems: IMSAI 8080.
Most Altairs were powered by the Intel 8080A The Altair Disk subsystem consisted of two boards and the disk drive. Here is the first of those boards. This is the second of the Altair disk boards. The connector on the first one hooks up to this one and then the cable hooks up to the remaining pins on both boards.. An original Altair 8800 front panel circuit board won#39;t mount properly in the Altair Clone front panel bracket, so you#39;ll need to use the new front panel board set mentioned below. The most recent run of the cabinet includes pre-drilled holes that line up with holes in the 9-slot motherboard, or with two of the Altair 4-slot motherboards see.
IMSAI 8080 Resurrection | Hackaday.
The entire Altair 8800 system is comprised of a metal case, a power supply, a front panel with switches, and a passive motherboard with expansion slots. All of the circuitry - the CPU and memory, are on cards which plug into the expansion slots, which MITS called the quot;Altair Busquot. When an interrupt occurs, this chip generates an interrupt signal to the 8080. When the 8080 acknowledges the interrupt, the chip provides a RST Restart instruction that causes the microprocessor to save the current program counter and branch to address 0000h, 0008h, 0010h, 0018h, 0020h, 0028h, 0030h, or 0038h depending on the interrupt.

I can#x27;t afford a real Altair so I#x27;m making an emulator with GameMaker Studio. This version has all but one of the features, Read/Only ROM emulation. I#x27;m not. Altair 8800 is one of the oldest commercially available computers overall. Ed Roberts founder and CEO of MITS corporation was selling these machines by classic mail directly from the factory. Various enthusiasts understood the power of Altair and started to develop software and hardware for the computer. Those people saw a freedom in Altair. David Hansel has also made some awesome updates to the software that will enable you to upload and save software to the SD card, emulate a 5MB hard drive, support multiple serial ports, emulate an Intel 8080 or Zilog Z80 CPU and more!

June, 1978 Altair production discontinued: Original Price: Altair 8800 computer: 439 kit, 621 assembled includes CPU board, front panel control board, power supply, and expander board Expander board adds 4 slots, 16 kit, 31 assembled 1K static RAM: 97 kit, 139 assembled 2K static RAM: 145 kit, 195 assembled. By late 1975 they were shipping what was to be the first Altair clone. IMS were able to correct many shortcomings of the original Altair 8800 by providing a larger power supply, a 22 slot motherboard, and easier wiring of the front panel. Willard famously went on to found ComputerLand and become known as the quot;fatherquot; of modern computer retailing. Additional 4 slot motherboard kits with 4 card edge connectors are available at a price of 90 each. The kit comes with a guarantee that you will end up with a fully functional Altair. As long as you make a good effort at assembling the kit, and pay shipping both ways, I will diagnose and repair your kit for free.
