IMSAI 8080 S-100 Computer Advertisement Scan - 1977The only winning move is not to play

Here’s an oldie but goodie — the IMSAI 8080, a 1975 clone of the pioneering Altair 8800. Like the Altair, it used an S-100 bus, an Intel 8080 CPU, and a blue, boxy sheet metal case with front panel lights. Unlike the Altair, the IMSAI 8080 featured prominently in the 1983 movie WarGames. The machine apparently greatly annoyed Ed Roberts, the inventor of the Altair.

Vector Graphic Inc. Vector 1 computer system advertisement - 1977NOW AVAILABLE IN RUST

The Vector 1 (1977) was the first complete computer system sold by Vector Graphic, Inc., a California-based firm founded by Lore Harp (now McGovern), Carole Ely, and Bob Harp in August 1976.

The Vector 1 included an Intel 8080A or Zilog Z80 CPU, and it utilized the S-100 bus introduced by the Altair 8800. In an unusual nod to aesthetics, the Vector 1 shipped in two case color options: green or “rust,” which was Vector’s name for orange. It retailed for for $849 fully assembled (about $3,288 today when adjusted for inflation) or $619 as a kit.

It just so happens that I wrote an article about the history of Vector Graphic for FastCompany recently. You may enjoy it.
