Could some appropriately skilled solder-jockey replace those 8 chips with, say, the 8 chips on this 32MB SIMM sitting in the slot next to them? (Actually now that I look closer, the number of pins on each chip on this SIMM is different than the chips on the LB, so that specific example wouldn't work.) Are there higher capacity chips that could be swapped in, to boost the total RAM available? I assume these are each 1MB chips, are there some 2MB or 4MB chips that are the same form factor?
