A Tandy / RadioShack TRS-80 Model 1 Clone

I did pretty much the same, although I managed to get the 16k RAM version. I've still got my old TRS-80 in the loft, eventually with the expansion box and couple of disk drives. Each single-sided 5.25" floppy held a massive 90k, then someone worked out that if you punched a timing hole in the cover in the right place you could put the floppy in upside-down and use the other side too.

Like you, I cut my teeth on the TRS-80 and wrote my first commercial program around 1982, a graphics drawing tool (written in Z80). It sold maybe a dozen copies, but was a start. I've got fond memories of EDTASM and T-BUG, the assembler and debugger.

I'm also have a similar background (although the first computer I used was my school's PDP-8i via a teletype). I still have my Model I and all the assorted accessories. I remember moving from EDTASM to Microsoft's Macro Assembler for the Z-80 assembler I write.
