Not so long back I got a mail from Rick Reed asking me if I'd
like a TRS80 (often called 'Trash80') Model 1. Of course I would! Being slightly
unemployed at the time meant I could drive across the Pennines to pick it up on a sunny
day in February.
I wasn't expecting the amount of stuff there was! Everything was
boxed - Model 1 itself, Monitor, Expansion Interface, Floppy drives, plus there
was a box of disks, 2 boxes of tapes and 2 big boxes of documentation.....smart!
Unfortunately the machine isn't well and I lack an Oscilloscope
to troubleshoot any further than I already have, with help from Tony Duell and
the regulars on the comp.sys.tandy newsgroup. It behaves as expected without
ROMs so the CPU is running and main memory is happy, so the problem must be
either the ROMs themselves or a fault on the data lines going to them.....troubleshooting
those requires extra kit so until I can get some spare ROMs the machine will
have to stay unwell :(
The machine had been upgraded at time of purchase, according to
the receipt, so it has Level II BASIC (not the Level I 'Tiny BASIC' which only
had 3 error messages - 'ERROR', 'HOW' and 'WHAT'...hehe) and a lower case modification
that added an extra screen RAM chip and some wirewrap wiring.
I've just realised I haven't got pix of the Expansion or floppy
drives. Clever me.
