In the course of trying to narrow down the problem, I tried removing
every SIMM and DIMM from the board (more on this later) except for one
pair of memory modules in bank 1. Lo and behold, though I still got no
video, I could hear it accessing the hard drive as it booted. So I
reinstalled the VRAM (two modules, out of the four available slots), and
lo, it still booted, with video this time.
So then I reinstalled the cache, and it still worked. Then the
remaining RAM, one bank at a time, and lo, everything works.
The one oddity was I realized for the first time, when pulling
everything out, that it had seven of the eight memory slots populated.
Right, three and a half banks of RAM. Which was doubtless playing merry
hob with interleaving.
It's now running on six modules in properly matched pairs for a total of
208MB of RAM (I haven't looked up the part numbers, but I assume that's
2x64MB, 2x32MB, 2x8MB). And it's now been relocated as originally
intended to a table where it has a good beefy surge suppressor.
(I don't suppose anyone has any spare RAM or VRAM that'd work in a PCI
I also noted during the process that this thing appears to have two SCSI
buses, or at the very least has two internal SCSI connectors. I was
slightly surprised at that. Still narrow SCSI, of course. Sometime I
need to track down an Apple disk sled and throw a second hard disk into
it... the existing disk is a mite small.
