Last night (09:00 to 04:00) we re-assembled all the parts, checked
cabling again, took off all boards and gave it a first run (without any
load). The fans went on, power distribution module's LEDs, too.
As the next step, I re-inserted one of the CPU modules and one memory
module. Tadaa! Nothing explodes, just seems to work. We'd watch the LED
showdown while the CPU was running it's self tests.
Insert 2nd CPU module and the other two memory boards, power on, nada.
Both CPUs toggle between error 1 and error 6. After checking some
combinations, one of the -3- 32MB modules seems to be broken. (Maybe I
killed it? :-( ) FDDI card also came up in the next step.
Then we inserted the XMI-BI modules (as well as both BI adaptors on the
BI side) and two additional modules. Works. Then all the rest (except
the faulty memory module). Doesn't work. One of the XMI-BI adaptors (XMI
side) didn't come up. After cleaning contacts once more and some
remove/insert cycles, it's up again. Also, all cards of the BI side are
properly reported. Unfortunately, I haven't logged the console session,
but here's from pure memory what this machine consists of:
- 2x KA62 CPUs
- 1x FDDI adaptor (for XMI bus)
- 2x working 32MB memory, one 32MB module is faulty
- 2x XMI-BI adaptor pairs
- 2x DEBNI
- 2x CI
- 1x DMW32 (?) --> connects to a printer port, a number of async ports
and one sync port
- 1x TK70 controller
- 1x TOYsomething (cannot correctly remember it's name, nor if/where
backplane cables were wired to or what it could be used for)
- 1x USV battery pack (seems non-working at the moment, at least one
fuse is broken)
It's somewhat sad that one of the memory modules is faulty, but overall,
after some cleaning, the machine is in quite good shape. It came with a
piece of paper with a printed gravestone: 1989-2003. It's really a nice
beast. With as much disassembly as possible, we were able to get it down
into the basement with four people. But let me tell you: we were quite
sweaty when we had out final touchdown...
Some words to the faulty memory module. I would have expected that, as
long as a working module is there, one faulty module should just result
in an error message in the POST stage. But unfortunately, the machine
really hung during the extended self-test phase. Within 15min, it didn't
manage to finish and continue. During this time, either the bottom-mose
LED (1) or the two above (2+4=6) were lid. Does this ring any bells?
Maybe the module isn't all that bad, but only some cold solder marks?
