Hi all!
After researching a bit, I'm still a bit confused about the subject... it's clear that both machines will work fine with 8 MB (eight 1 MB SIMMs) and that MODE32 is required in order to recognize larger amounts (32 bit addressing). But:
•My II is pretty stock -- no PMMU (has the Apple kludge instead), standard ROMs (no FDHD). Does it really need the 68851 PMMU for anything over 8 MB? Is the Bank A limited to smaller SIMMs than Bank B?
•My IIx booted fine with four 2 MB sticks, but were detected as 1 MB only Those very same SIMMs make Death Chimes on the SE/30... Will regular 4 (or 16!) MB SIMMs do?
What's a PAL SIMM anyway? My 2 MB SIMMs do have a (PAL?)16L8 chip and four 514400 DRAM chips. They work fine on the Colour Classic, though.
Thanks a lot in advance!
