Does the cube recognize the configuration or would I have to change anything (like jumpers, non volatile memory ...)? And, of course most important of all: Where can I get 4 MB SIMMs? How much do they cost? Richard

Speaking about 4MB SIMMs, I've been wondering about something. When the NeXT comes up, it reports various I/O devices at addresses like 0x2000000 + something (such as SCSI, sound, etc.), which is an address at the 32MB boundary. I wonder if this could interfere with expanding the machine past 32MB? It should be able to take 64MB on the main board. I suppose the machine could map the memory further up, past the I/O physical addresses, and you'd never know the difference. But has anyone (including NeXT) run the thing with 64 (or 48) meg of RAM?
