I had a lot or fun adding 6 mb of 80 ns DRAM to this recent purchase, and am now trying to see what will fit onto an AE Ramkeeper in a ROM3 IIgs.
I will try to see if it will work with a Sirius 8mb card in addition to the GSRam Plus for 16Mb total. Then I'll see how fast I can run the TWGS with all that.
I will post photos of all this when complete. Willing to pay the going market rate, but don't know what that should be, since i've never seen one anywhere.
Working or dead, schematic? PC board layout or photos of one? I might be able to replicate one if I was able to get one on loan.
Of course, I'd pay for it in advance, and you could charge me to rent it long enough to replicate one.
Here 's a photo of the front:
