We fixed a few Multias here with 74FCT623 parts, they run even cooler than
ABT and are made by more mfrs.

Another thing you might do: if your Multia still runs you could buy some
thermal epoxy and heat sink it...but it will be's on the bottom
of the card and there isn't much room to work with. A block of thermally
conductive something ... best case: silver, copper, or aluminum ... coated
with thermal grease and wedged between that chip and the bottom of the
case, now that might work.
