Wanted: Replacement PAL chip for A3000 motherboard, component number "U202",
this is a 16L8 PAL with foil sticker marked
(c)1989 CBM
390526-02
Also need one or two replacement batteries for the A3000 clock.
If you have these parts or phone numbers of sources, please reply. Thank you
very much.
By the way, the failure of this part in my machine caused random screen jumping
and trashed pixels when I clicked the mouse or when there was heavy traffic on
the CHIP RAM bus. It also caused random read/write failures of the floppy
drives. Anyone experiencing these symptoms might want to check U202 or the
associated Agnus chip.
Thanks again for any help.
