Cassette tape was also the format of choice for my Atari 400, but I had the computer for a year before I got the tape drive. So for a year I had to retype my BASIC programs into the 16k of RAM every time the computer got turned off. On the membrane "keyboard".

I remember wishing I had an Atari 800, which had 64k of RAM and a real keyboard!
