So here's an interesting problem. I've got a (as far as I can tell anyway) perfectly functional Mac IIci. It's been recapped. The logic board is clean and there was very minimal corrosion. Everything seems to be working. I've run Mac Test Pro on it. Everything checks out.
However, if I turn on virtual memory, on boot it always bombs out with "Error Type 7" (which I can't seem to find much information on.)
I've reinstalled the OS several times, on 2 different disks, and I always get the same thing. Now to be fair so far I've only tried system 7.1.1 with Update 3.0. I'll probably try 7.5.3 soon. I've also tried with different SIMMs and with the cache card removed.
Is it possible I have a bad MMU somehow? From what I understand the MMU is required to some extent for the system to work at all (non-contiguous memory). What gets me is, I think virtual memory was working in the recent past on this system.
Anyone seen anything like this before?
