I love the way you took my grandiose schemes for the IIsi and came up with your own plans, attacking it from the IC side of Bank A there and for the Q605/LC475 here. You don't need to credit me for the IIsi idea. Great work there, uni!
The info in the thread you linked to is much more applicable to the 605, not so much the LC475. The MicroQuadraFeetsMac™ has handy, removable ribs hidden within the deeper, flat-n-feeted case. I posted the riddles/info in the IIsi thread to help, definitely not brag, I didn't want to steal any volume from your thunderous achievements. I love collaborating on a hack from multiple fronts. My back-burnered hacks would likely never be realized otherwise . . .
. . . now you can work out the mapping for 320MB or 512MB of 72-pin SIMMs in the 605! }
Removing the ICs from Bank A is a great start, BTW. De-solder the thru-holes for the unimplemented ROM SIMM for routing your jumper wires. and take the hack underboard/subterranean/fairly stealth, as I'm doing an under the board IIsi PDS hack. Only you won't have to cut a hole in the bottom if you use flat 72 pin SIMM Sockets or just solder them directly to the PCB at a very low angle . . .
. . . its not like you'll ever really need to upgrade the RAM again! :lol:
I'm glad you started this project, it gave me a big kick in the butt on a lost hack. I'd posted it by mistake in 68k LC & Performa instead of Mac II, Quadra & Centris for folks interested in the 605 might take note of it. I guess it really belongs here in Hacks & Development. I found it only by searching for the IIsi info, it never made it onto the crib-sheet topic I made for my projects.
