My first computer (actually my second as my sister broke my Atari 400):
Atari 800XL (still works and I still turn it on every now and then)
Have the Enhanced floppy drive model 1050 (a whole 170k per side)
Have the 4 color plotter/printer
Have the tape drive (back in the day, before floppies, we used cassette drives for storage)
Total cost at the time: $1200
I remember waiting 60 mins for Jumpman to load from cassette only to fail loading at the end. The good old days. Floppies were 10 bucks a pop.
