These are all tested not working vintage 74 series TTL ICs that have been removed from the historically important first commercially available coin-operated video arcade game - Computer Space. Would make a great display or conversation piece, these chips witnessed the birth of a new industry that has changed our society forever! I repair these PCBs for myself and sometimes for other people, and can guarantee their provenance! Although the game was 'released' in 1971, the fact is they were still making and selling them into 1973.

All chips are made by Signetics in their characteristic light-grey plastic N package.
