Your wierd problem is most likely caused by a bad 8520 chip.  I had problems
once very similar to yours and it was fixed by replacing one of the 8520's.

These chips are Commodore's custom serial, timer, VIA chips.  They are locateded
in the back right corner of the motherboard near where the floppy cable 
connects.  You can get them from any C= dealer.

Hope this helps.
