Imsai 8080

I am no longer active in this hobby for the foreseeable future. 
I will no longer maintain or update the website, but I will leave it accessible to the web for as long as possible (years).

IMSAI 8080

This one has the reputation of being the first PC clone--it copied the bus and general feel of the Altair 8800, but did it with power. A bigger and better power supply, and a more powerful look and feel. It just looked more professional, industrial.

I've always wanted one of these! Back when I was selecting my first computer, I considered this one, but as it was very newbe unfriendly, and required lots of extras just to match what came standard with The Digital Group, I opted for the latter.

This one was a gift of Tom Apel, who interesting enough, has thedigitalgroup.org web site.

Restoration

This is going to take a long time--I am so busy! I noticed one thing about this computer almost instantly: Those paddle switches are fragile! This lesson was learned, thanks to my sweet daughter.

I'll update when I have made some progress

IMSAI Simulator

Years ago, I ran across this little program that simulates an IMSAI 8080. I have no idea who wrote it--all apologies.
