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,

Earl Evans
