You can use a 501-1131 2MB or a 501-1132 4MB memory board for expansion.
I think I have some.

UE      Uncorrectable error (when lit)          RED
CE      Correctable error (when lit)            YELLOW
DIS     CPU access disabled (when lit)          YELLOW
CPU     CPU accessing memory                    GREEN

When the 3/200 CPU configures the board the DIS light should go out.

The CPU goes in slot 1 (far left) and the memory board goes in slot 2.
It should work like that.
