IMSAI Advert - January 1977

"Experience the excitement of owning the finest personal computer - IMSAI 8080"
Another advert for the IMSAI 8080, as used by Matthew Broderick's character David Lightman in the classic nerd-film "War Games", but at least when this advert came out the machine was actually new (War Games wouldn't be made for another six years). It retailed for $931 assembled (about £3,600 in 2011 terms), ran an Intel 8080 and had 22 expansion slots on an S-100 bus, all of which was fed with a 28 amp power supply. This style of input, of using switches for programming and using lights for feedback (which was arguably only of interest to hobbyists and science-types) was the standard for most computers at the time. Keyboards and video displays were available, but generally only as expensive add-ons which would be out of the reach of most home users' budgets. The last computer to feature this interface is considered to be 1981's Ithaca DPS1, which is right in to the era of the IBM PC.
