  Finally, a question that I can at least suggest an answer to!  Having
a little experience in this matter, I think that you may be on the right
track, tho checking the PAL may be a wise decision too...  At any rate,
the ROMs are probably soldered into place (2 out of 3 machines in my
experience) so removing them is NO FUN!  The 6526's are your CIA's -
it's probably not them, when they fail, your serial port dies, as does
your keyboard and other nifty things! :-)  The 6581 is the SID (if I
remember correctly, it's been a while).  The "burp" you mentioned
probably means it is OK.
  I believe the 906114 -01 is the PAL in the beast, and you should probably
check that one first.  Any decent repair shop (c64) should have them for
about $15.  If not, Jameco will sell you one for that and shipping.  I don't
remember the number of the ROM, sorry.
