I did get this last Sunday - about 5 large boxes of manuals, binders,
floppies and tapes, plus the computers.  I did find time to fire up
the Model III, unfortunately, it seems to have a problem - no text on
power-on, and no indication of anything running except for the usual
drive 0 spin up and access light for about 2 seconds.  The screen has
power - you see a white flash and squiggle on power off (usual mono
CRT shutdown kind of flash and squiggle), but never any text or
fragments of text.  Pressing the reset button does get a power-on-type
reaction from drive zero, but that's it.

It's been about 22 years since I used a Model III, so my memory is a
little faded about it.  Are there any ROM-based diagnostics?  Anything
ever get spit out of the serial port?  I wish I had a Z-80 pod for my
Fluke 9010A (have 68000 and 6502) - it's a great way to sleuth around
inert micros.

Any and all suggestions (including schematics) are welcome, especially
if anyone knows of a site remotely resembling funet, but for TRS-80
stuff.
