You are probably talking about the spreadsheet of available parts. If a
part is no longer available at big parts places like Mouser, Digikey and
Farnell, then it was left off the list a few years ago, although I see some of
the unavailable parts have been added in as “Salvage”. I guess this is another
one for Jed to add. Salvage the thermistor.

Hi Bob... actually i realized about five minutes after posting that was the thermistor, though i missed it because i was working rather slavishly from Jed's spreadsheet which didnt seem to have it on there.
i DO have a scope actually. a lovely Tek 2445A. however I'm a bit
intimidated about troubleshooting logic circuits and signals....ive only ever
used it for analogue audio stuff really... so theres more to learn for me.
And i DID get some more functioning 5v test points on the board though
still not TP1 which is zero... and TP2 is a bit low at 4.1v or thereabouts. I am
a bit confused as the manual uses a totally different language like 'TP-J7' and
i am not sure how they correspond to the board ...
