Per page 2- It looks like since you have 4MB you don’t need any PALs, just the scrambled megs or an eeprom programmed with 8MB stereo already detected to add more memory (and the memory itself of course).

The empty sockets on the main board are not used.
The empty expansion board sockets (which are numbered )  should correspond to details in the memory guide page 6 and 7.
in other words- those numbered sockets which are empty should match the instructions in the memory guide for what should be filled.

Per page 1, the memory per 2MB is
Qty 16    of  44256     256K x 4 DRAM’s
 Whatever the memory speed of the chips -8, -10, or or faster.

For example, I would expect if you had some -8 on the expansion, you could put -8 or -7

Faster won’t cause you a problem, but slower could.

The PALs I have are:
