Yes, the SIMMs came with the card. You mean these 256 KB SIMMs are hard to find, or a GC board with any SIMMs at all?
The SIMMs are identical 64 pins, and the chips are marked "TMS44C256DJ" & "EDP 026J P" on one side, "TMS44C256DJ" & "EDP 026W 7" on the other.
The only other number I can see is '9035' & "ZA2982L" (very tiny) marked vertically on one side, and "BE3-0" on the other side on the end of the pcb.
Could well be 256 Kb, but can't they also be 2MB each as well? (256KB* 8) This states that the "Macintosh Display Card DRAM Expansion Kit" can add 2MB more, but 3rd party SIMMs can expand memory up to 8MB. Optimistic, I know :lol:
Acording to this ROM version identifier it have a rev B ROM (341-0266). 1989,90.
