Greetings,
I've got a Commodore Plus/4 that's not working quite right.
When I turn it on, it does power up, but doesn't boot to BASIC. Instead,
it
"breaks" into the machine language monitor.
The following is displayed:
BREAK
PC SR AC XR YR SP
;8008 B5 08 00 00 FF
Looks like one of the chips is fried, but which? My initial guess is
either
the Kernal ROM or BASIC interpreter is shot.
Any guesses? And does anyone know where I can find some Plus/4 spare
parts?
:-)
Thanks and best regards,

Im trying to remember if there is a combination of keyboard strokes toat
allows it to boot up into the monitor. I'd check to see if the keyboard
might or might not have a short across two of the lines, or if the CIA
scanning the keyboard is shot.
