CBM Plus/4 malfunctioning...can anyone help?

12 Jul 2000

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,
