     According to our Memory Expansion Card Owner's Guide, there are two
recommended upgrades:

512kB (top row filled-- 16 chips):      jumper on lower set of pins
   1MB (both rows filled-- 32 chips):  jumpers on both sets of pins.


     The manual says that the 768k upgrade (i.e., 24 chips on the card) is
not a good idea "because some applications have trouble dealing with that
configuration".
