Hey.
I picked up a freebie CBM/PET 8032 system with dual disk drive and Z80 board
a few weeks ago. It didn't power up. I put it on my workbench and opened
"the hood" to suddenly find out that the CRT was not secure, because it hit
my workbench neck first, and broke the clear glass at the end of the tube. I
was wondering if it is possible to find a replacement tube. Could I somehow
(on a really long shot) get a same sized CRT from a black&white TV to fit
inside and work?
Almost certainly yse. Monochrome CRTs are pretty generic.
You need to find one with the same diameter neck (there are basically 2
sizes) and same pin base (this, I think, is 'modified B7G' with 7 pins).
Get that right, and you'll have a CRT that is pretty much going to be
electircally similar.
Keep the PET's deflection yoke (don't try to use the one from the TV).
