Looks like there is 2 different kinds of Classic II main boards.

Looks like the main difference seems to be the ROM I/C's.

The Earlier Classic II Version had 4 ROM I/C's



The Later Classic II Mainboard had only 2 ROM I/C's



I was going to maybe start by experimenting, and changing the later CLASSIC II's Roms with maybe ones from a LC-III.

see what that does?

Maybe slap a couple of 16mb simms in there?

Anyone have any ideas? If that doesn't help, I would like to find the what is limiting the ram...
