I did the same with an Atari 400 that had a cassette tape. I remember it would take 30 minutes or so to load/save games I copied from magazines. The keyboard was torture. I then moved on to very rudimentary text adventures of my own once I felt a bit comfortable with BASIC. I'm very glad my father bought that for me...he was a painter and we didn't have a lot of money then. It was extremely formative.
