In the good old days, back when the Internet had about 10 users and the web was a far off vision, PCs were called Home Computers and anyone could learn to write computer games. Three of us set up in business to write and sell our own games for the ZX Spectrum (Aka Timex/Sinclair) and Commodore 64. We didn’t sell many games but we were saved by getting into the game conversion business. A publisher would release a hit on the Commodore 64 and we’d write the Timex, Amstrad, MSX, CBM 16 etc versio.
