Well, it turned out to be a rather successful day with the machine. All
of the boards proved to be OK despite the power supply explosion the
other day. The replacement caps in the PSU seem to be holding and doing
When it got to be time to check out the disk cabinet, the PSU in that
checked out OK (apart from one noise supression cap letting go). So,
hooked it up to the disk and powered it up without the CPU. No horrible
noises (except for the case fans - bearings are shot), and the drive
ready LED came on. So far so good.
Hadn't found any external SMD cables at that point, so took the case
sides off and ran ribbon cables directly from the CPU cardcage to the
Hooked up a vt420 terminal on the first serial board, and fired it all
up - success! It's running SunOS 4.03 - after an initial fsck it booted
to multi-user mode.
The Ethernet card may be a source of trouble. It seems to want something
that provides an external heartbeat - we hooked up a DEC hub to get
around that problem, which stopped the "no carrier" messages on the
console. However, it's still throwing up "Ethernet jammed" messages -

Also, the disk isn't perfect. It's thrown up a couple of unrecoverable
ECC errors during the time we've had it running, so there are definitely

used post-install? (Probably not though - it usually seems to be an

but then using the 19" mono screen and a terminal console just for input
seems to be working just fine, so that's no big deal...
