I’d had games machines before this (Atari, BBC Micro, Vic20) but didn’t really do anything other than play published games.
One day a Mac SE appeared at home courtesy of my sister and it hooked me immediately. I started using it to design stationery and flyers for my first business. This led to me buying my first personal computer (from Tandy) running DOS. Having played with DOS, I progressed to machine code and designed a database program to manage my music collection.
