I used a couple of IMSAI 8080''s at NASA in the early 1980''s. Each had a Z80 4MHz CPU and 64KB of RAM. For storage each had a dual set of 8-inch floppy drives. Each also had a 5MB hard drive but were never used much because they were not very reliable and eventually failed.

Raindance Rob - it was indeed used in War Games (check out Fire in the Valley by Paul Freiberger and Michael Swaine)

looks like what David played by Matthew Broderick used in the film Wargames, can anyone confirm ?

now that's what I call oldschool! Respect to all who have been using this piece of fine equipement

I learned BASIC and 8080 assembly as a wee lad on one of these. It was owned and tricked out by a housemate, Gail Marshall. He wrote his own keyboard drivers and graphics libraries (so he could do the Game of Life) as well as an implementation of LISP. He hacked an Olivetti daisy-wheel typewriter into a printer! Gail was truly a Real Programmer. We still have a box of 8" disks around somewhere...
