TRS-80 Model I: http://en.wikipedia.org/wiki/TRS-80

I loved the TRS-80. We had some in my Jr High. We had an assignment to create some large ASCII art via hundreds of print statements and then print it out on the dot matrix printer.

I also had a home computer featuring a Z80 CPU, compatible with the Sinclair.

But this one also featured a 3.5" floppy drive: http://www.old-computers.com/museum/computer.asp?st=1&c=...

Sadly I sold it to a friend at some point.
