IIfx SIMMs are just a side issue, but don't VRAM ICs work similarly to the IIfx's Dual Ported (?) DRAM ICs? Dunno . . . :-/
The real reason for this thread is to expand Apple imposed Q605/LC475 and IIsi memory limitations by building an adapter card that'll use more modern (faster response times) SIMMS on a sub-mobo memory expansion card that'll address all available RAM Banks at maximum capacity.
The Q630 and its variants could also benefit from such a board, as well as almost ANY Mac with a piddling 4 MB of onboard RAM.
I'll have to check my archives for the original "EVIL MemHack" info/threads. I was hoping the maniac still had that info available, IIRC, she's the one who posted the links.
. . . or that some eager comrade would jump in, search them out, and post them! [
