I could not figure out how to wire the tens of hours module to the hours
module. The magazine article was very vague and even misleading about that.
So one night I sent an email to Gary Kay, the designer, and the next
morning I had a response. How is that for tech support 35 years after
the fact?
Grumble Grumble Grumble ... Gripe Gripe Gripe.
I would have updated the high voltage power supply to a simple
transistor regulator. I have about 128 AC around here and that
can really give over voltage on 115 V transformers.
PS. Where do you find a 300 V transformer ... I may build one
some day. Also any options for a ALARM feature? Say a analog
bird chipring sound?
Gary Kay later designed many of the SWTPC 6800
computer systems.

I keep drooling over SWTPC products... I
wish that made it big
rather than PC's.
