The PAL chips provide all the address decoding, bus control, timing,
refresh garbage for the RAM, etc. etc. (see first issue of MacWorld
or February '84 issue of Byte magazine). When upgrading from 128K
to 512K, its probably necessary to decode a few more address lines
thus requiring a new PAL chip as well as new memory chips.
Is this the type of comment you were looking for?
