The first one was a C64, with a tape unit. I remember I created a routine in 6502 assembler to quickly start the graphics screen, since the Basic version was too slow. I also acquired a Pascal compiler with possibility to create sprites...
After this, in my first year in Uni I bought a PC with 2 floppy drives (no harddisk - way too expensive). 1 floppy contained command.com, and on the other I had TP 3.0 and used it for my assignments.
