Just bought a new keyboard for my peecee, so I figured I'd break it in a bit. I LUUUURVE scissor keys.
AFAIK, the Mac TV was the only Mac where the Apple-specified limit was actually adhered to; virtually every other machine could accept waaaay more than Apple claimed. I've got a small cache of 64 and 128MB 72-pin SIMMs, and in all the machines I've tried them, from LC IIIs to 8100s, they've all been recognized fully. A 6100 with 264MB of RAM (128x2 + 8MB soldered)is a trip. So is a Quadra 840AV with 512MB (128x4).
The PowerBook 2400c is quoted by Apple as having a max of 80MB (64MB SODIMM + 16MB soldered), though a Japanese company made a 96MB SODIMM that brought its max beyond that limit to 112MB.
Really, the limits are set when engineers test the maximum of readily available RAM modules, and you know how technology can progress.
Then, of course, there's the Mac TV. It completely refuses to use more than 8MB of RAM. Something about the weird circuitry they used to accommodate the TV system, I dunno. But it sucks, and a stripped System 7.5.5 with ClarisWorks 4.0, maybe with Oregon Trail or SimCity 2000 for games, is all I care to run on that thing.
