Altair 8800 Emulator Kit – Assembled & Tested | Adwater & Stir.

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 "Altair Bus". An Intel 8080 (and later the 8085) or Zilog Z80 microprocessor At least 16 kilobytes of RAM (beginning at address 0) A means to bootstrap the first sector of the diskette At least one floppy disk drive Compare that to a Hy-Tiny and you can see the. A beautiful ESP32 software emulation of the Altair 8080 with VGA and PS/2 support. 218 views.... FYI: I have a TTGO board running runcpm and it stores the CPM software on a sd card (sd card slot was on the TTGO board). Richard Deane. unread, Jul 30, 2019, 10:36:35 AM 7/30/19.

The Intel 8080 is an early 8-bit CPU, released in April 1974 running at 2 MHz, and is generally considered to be the first truly usable microprocessor CPU design. It is the successor to the Intel 8008, with which it was assembly language source-compatible because it used the same instruction set developed by Computer Terminal Corporation.

This means that the MicroSD slot is not necessary any more, as well as the SRAM chip. The code runs faster on a Raspberry Pi as well. I would recommend this route for anyone interested in their own panel. Todo. Separate the Intel 8080 emulator and the Altair 8800 hardware emulation. E.g. make the port IO more abstract instead of 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 8800’s initial team of creators consisted almost entirely of United States Air Force veterans, many of whom were still serving when MITS was founded.

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.

The Altair kit, considered by many to be the first personal computer, included an 8080 processor, a power supply, a front panel with a large number of lights, and 256 bytes (not kilobytes) of memory. I've been working on building an IMSAI 8080 CP-A Front Panel replica since May 2017. I first ported Udo Munk's z80pack V1.36-dev, specifically the imsaisim machine, to the ESP32 micro-controller targeting the ESP32-PICO-KIT. These devices have a dual-core CPU @ 240MHz, 520KB SRAM, 4MB Flash RAM (storage) and builtin WiFi, USB connector for.

Altair-Duino. Dimensions: 15″ x 6″ x 2″. Weight: 2.5 lbs. RAM: 512KB (64KB maximum for Altair emulation, the rest used as storage for Altair programs and utilities.) Storage: Micro SD card with megabytes of classic software included (CPM, Altair DOS, BASIC). The Altair also led to the creation of the hugely popular S100 bus, used for plugging in expansion cards - a foretaste of what we would all being doing for decades on machines ranging from the Apple II to the IBM PC and its countless clones. Wanting an Altair. The idea of being so 'close to the metal' fascinated me. Starting in 1977 IMSAI officially supported and sold "the Megabyte Micro", an IMSAI 8080 loaded with sixteen 64K DRAM boards. (This left two of the eighteen slots free for the CPU and I/O.) I have not seen such an expansion advertised specifically for the MITS Altair 8800 itself.

IMSAI 8080 22-slot chassis; Northstar 8MHz Z80-H CPU; 64K static memory card... everything go up in smoke, or watch a couple of 22,000uf caps grenade. The front panel can't single step or examine memory at 8MHz. If I remember correctly, dropping the CPU speed via the switch on the CPU card will put the clock into a range where the front panel.

The IMSAI 8800. The IMSAI 8800. Although the MITS Altair 8800 was the first practical personal microcomputer and started the industry, credit for spreading the personal computer revolution must go to another company_IMS Associates and its product, the Imsai 8080 computer. While it was not strictly a clone of the Altair, this machine adopted the. The Altair 8800 is considered the very first personal computer in the history of computer science: it was easy affordable and obtainable.... that was connected with the CPU and the main memory (placed on separated slots) through a bus called S-100 bus (Altair bus). Inside the ROM was inserted an Altair BASIC programming language ( a simplified.

For some reason, the January 1975 issue of Popular Electronics magazine, featuring the Altair 8800 Minicomputer construction article, seems to be the most highly prized of all editions ever published. They regularly sell on eBay for anywhere from $200 to $500, depending on the condition. If you happen to have one or find one at a yard sale, hold on to it as an investment (or mail it to me and. This Rev 0 CPU card has the rare Intel 8080 chip. Most Altairs were powered by the Intel 8080A.... One of the 4 Seals 8k static RAM cards. The Altair 8800 came with 32k of RAM on 4 Seals.

MITS Altair 8800 Power Supply - V.

The computer they designed, the IMSAI 8080, was very similar to the Altair 8800 and was designed to run the same software. However, it was a much better design, with a higher specification power supply, an anodized aluminum chassis, 22 slots on the S-100 bus, and a great front panel design. The IMSAI 8080 aimed to take advantage of the Altair's. Kean, I remember a two byte memory clear program for 8080/Z80 - 0000: 33 C7 You might have to run it twice to clear all memory. I think it'd be a good test of the emulation. In 1976 I assembled a MITS Altair in a weekend for school. Lots of fiddly stuff there - the Imsai's design was better. The Fulcrum I-8080 I found has no memory or drives, but includes a Jade Big-Board Z80 CPU (rev C), a Fulcrum VIO-X and Morrow Designs Disk Jockey 2D/B floppy disk controller. It also has mostly original IMSAI chassis metalwork, and the Fulcrum updated replica IMSAI PS28D Power Supply, a Morrow Thinker Toys 20 slot active terminated Wunderbus.

The MITS680 is not S-100. While the MITS 680 uses the same 100-pin edge connector as the MITS Altair 8800; it's not S-100 compatible. The 680 bus boards' edge connector is in a different location than the MITS Altair 8800 boards and other S-100 boards. And, the MITS 680 bus signals are on entirely different pins. 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". 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.

The AT introduced the 80286 as well as 16 bit expansion slots. The XT came with a hard disk so there weren't any XTs with dual floppies (the hard disk occupied one of the two drive bays) Between Apple, Atari, Commodore (6502 family), Kaypro, Eagle, Osborn (8080/Z80 running CP/M) and dozens of others, there were millions of "personal computers..
