This disk drive was intended for use with the Tandy model 100 and 102 computers but works great with the Atari Portfolio used to hack an ATM in the movie Terminator 2.
0:40 Speed to make a Commodore user jealous. ;p 4:52 I've had problems with using rubber bands as drive belts. They're too soft, so there tends to be lots of flutter in the speed.
I had one of these drives with a TRS-80 Model 100. I hardly used it, then tore it apart to see how it worked. I was a dumb spoiled kid. The barcode wand got a tiny bit more use. Figured out how to plot 3of9 barcode on a pen plotter and read it with the wand.
