Used to play a lot of Doom. I bought ver 1 on floppy.. A buddy bought the beta version .666 on floppy. I played it on his system then rushed out about bought ver 1. Seems I got it at Fry's Electronics in San Jose. Fry's was the 'everything pc' store on the west coast back then. The whole bay area was the new silicone valley by the early 90's. I worked in south san fransisco. Seems everybody and their brother had a T-1 phone connection and server in their garage.
