This was a clone of a TRS-80 Model I with Level II BASIC.
I have been unable to find out any information about the manufacturers
apart from they marketted these machines under different names in
different contries. In Australia they were called System-80, in the USA
they were called PMC-80 and in South Africa the TRZ-80.

24/01/1996 - The graphics are screwed up. This is caused
by one of the 2114 video memory chips being broken. The effect is
that the lower four bits of all video memory is set on.
06/04/1996 - I replaced both 2114 video memory chips and the
machine is back to full working order. I was even able to load and
play Arcade Scramble from Kansas software.

08/04/1996 - There is what seems like a video memory
problem with this machine also. Time to replace the 2114's to see
if it clears it up. There is also a minor fault with the cassette
player. The spring that lifts/ejects the cassette lid is missing.
