Yeah, I had a Timex/Sinclair 1000 Z-80 with 64 K ram (if I attached the
add-on ram block). It came with basic built-in (keywords on the
membrane keyboard) but I also learned machine code on it. There was no
assembler program so I did it all on paper and entered it directly into
a memory block and then somehow (I forget) got that to run. Z-80 was a
nice little CPU and easy to program.
