Yep it is OK all you need do is exactly what you did for the 4/330 - the
second memory board will auto relocate it starting address to the first
hard LOC after the CPU onboard 32Meg.

I have not done this at all. All information I have says that the board
was designed to support 4Meg SIMMS so give it a go by.  First putting the
4Meg simms into the memory expansion board and see if the boot code in the
eeprom sizes the memory correctly

If so get some more 4Megs for the CPU.
