It was a cool looking box with four lights, toggle switches and one rotary switch that chose which of the 16 functions to display on the lights (before LEDs were common). Also the first computer I ever used that I actually saw was the Wang 3300 (Pre-2200 and quite rare!) and that computer was 74181-based. Tom L Cui bono? |
