Some 72-pin RAM SIMMs arrived today, bought and shipped two days ago. Postal service tends to be a day late because of the increased demand, but that's alright.
€15 for the lot, which is more than fair, I think. Untested, and the seller couldn't ID all of it, so my sleuthing comes down to this:
- Top left OKI MSC23232C-70DS16 double-sided pair is 8MB each, 16MB total. Not 100% sure if it's FPM or EDO.
- Bottom left LG Semicon GMM7322110CMS single-sided pair is 8MB each, 16MB total, EDO.
- Bottom middle Motorola MCM32T216SH70 single-sided pair is 8MB each, 16MB total, FPM.
- The four remaining sticks are Hyundai GM71C17403CJ6 double-sided, 32MB each, 128MB in total, EDO.
My hope is that I can succesfully revive my LS-486E board, and use the 32MB sticks to max it out at 128MB (according to online sources). The only confusing part is whether the board will support EDO or not. Online results are conflicting for the C revisions, some claim it does, some claim it does not. The manual I found for what seems to be this revision claims it does. The board came out of a beat up Photoplay 2000 cabinet, and currently doesn't work, but the RAM it was fitted with seemingly from the Photoplay factory was EDO too, so maybe it'll work? Maybe it's to do with memory density? We'll see, I'll first need to revive that board before I can test that. Either way, it's good to have this RAM on hand, I'm rather low on 30-pin and 72-pin SIMMs anyways.
