IMSAI 8080 EMULATOR MAC HOW TO
How To Get Into Cars: E85 Fuel 32 Comments They were the machines that really taught me about computers and electronics. Eventually I got a copy of WordStar running on it which was also pretty cool. Don’t know why but it always made me laugh.

It was hilarious because it was attached to the serial port and would try to pronounce whatever came out– sometimes I would glom it onto the terminal’s port and when I was in BASIC, it would print out “OK” which the speech synthesizer would pronounce “OCK”. That was one of my first wire-wrapped projects. Another project I did with it was build a speech synthesizer. I wrote programs to drive it around though it was limited to the length of the wire. One of my first robotics projects was using a tank toy chassis and a long cable back to the parallel port of the Altair. I think the parallel board was from Cromemco. I eventually got a two port serial board, some more memory boards, and a four-port parallel board. I was living in Dallas at the time and used to go to the local “Hamfests” to swap S100 boards.

In time I upgraded the CPU board to Z80, then Z80A and Z80B for an incredible 4MHz processor speed! And my Z80 board allowed me to upgrade the memory to a whopping 64k. I also implemented CP/M on them later and ran MBASIC. That was an unforgettable sound! My turnkey Altair also had two floppy drives and I loaded Altair BASIC from floppy. Talk about distinct sounds– that 14 inch platter sounded like a jet engine winding up to take off! Sheesh. One of my Altairs was the “turnkey” model with the 5MB hard drive. I usually ran one headless and the other with the terminal. I *loved* the front panel of the Altair, it was extremely cool. Posted in classic hacks Tagged altair 8800, arduino, cpm, intel, Intel 8080 Post navigation Everything you would want from a computer from 1975 is there an OS, BASIC, and enough I/O to attach some peripherals. This comes in handy, because is running CP/M 2.2 on this front panel emulator from disk images saved on an SD card. Everything is controlled by shift registers, but there is a small amount of SRAM in the form of an SPI-capable 23LC1024. The hardware began as a bunch of perfboard, but wired himself into a corner and decided to make a real schematic and PCB in KiCAD.ĭespite the banks of LEDs and switches, there really isn’t much to this front panel. The 8080 is the brains of the Altair, and while emulators are cool, they don’t have the nerd cred of a panel of switches and LEDs. The build unofficially began with an Intel 8080 emulator written for an Arduino. The 40-year anniversary of the Altair wasn’t forgotten by, who built a front panel emulator with the help of some much more modern components.

The January 1975 issue of Popular Electronics featured the Altair 8800 on the cover, otherwise known as the blinky box that launched a revolution, the machine that made Microsoft a software powerhouse, and the progenitor of the S-100 bus. It appears a very important anniversary passed by recently without anyone realizing.
