I had a tape drive with my Vic-20, but when I bought the C-128 it came with dual floppies. My dad bought it used from a guy in the Navy that was shipping out. He sold the monitor (TV), C-128, 2 1571's, 300Bps modem, a light pen, koala pad, 3 joysticks, 300+ disks FULL of crap, the desk, the chair, and ~300 Commodore programming mags for $1100. What a steal. I was 8 at the time. The thing I remember most distinctly was that there were 2 hustler mags mixed in with the techie ones.
At 8 it was unthinkable luck.
The Vic-20 was bought b4 I had any idea what money was so I have no idea. Same with the Timex Sinclair and the TI. The TI, btw, used a REGULAR tape drive with RCA outs as the tape unit. Wow. I'll never forget going to my best friends house when he got his new computer, and his dad forbiding me to touch it when he wasn't in the room. Now guess who calls every time his computer hiccoughs.
