Mine was a Timex-Sinclair, a similar US model after Timex got it. It was actually in the watch case at a department store. I also took some BASIC classes at the community college on TRS-80, can't remember which model, except it did have 5" floppy drives.

I got a lot out of the Radio Shack Color Computer. It was much more versatile than the IBM PCs. You could hook it up to a MIDI keyboard to play it, or to a shortwave radio to download and print out weather satellite photos and Wirephotos from news originators. With the PC, you had to buy a separate card for MIDI and another separate sound card to record from the radio.

My first PC compatible was a Tandy 3000NL in 1989. It was very useful, but only had a 20MB hard drive which cost over $700 extra.
