Hi again.
I realize I should repost my question under a differnt
subject line after having tread off such an avalange of
emails under the dishwasher and core memory subject.
O.K. I had it all in the dishwasher, except for the
PSU stuff with big transformers and capacitors and the memory
boards. I removed everything, including the backplane board.
I need to take some photos, that backplane is sure amazing
from the back. Now its about to dry and next weekend I will
reassemble and power up. Yea!
However, there are a few more issues to resolve first. The
little 16-pole ribbon cable that has DIL chip-like plug on
both ends that go into a chip-socket. That plug is bent and
pins are broken off. Seems like that happnes all the time.
Do I have to and if so how can I replace this? This cable
runs between the backplane and, I guess, the limited function
front panel.
Do I need this, is the limited function front panel needed
at all? What's the function of the 16 lines, I assume
- GND
- LED 1
- LED 2
- LED 3
- SWITCH 1 A
- SIWTCH 1 B
- SWITCH 2 A
- SWITCH 2 B
- SWITCH 3 A
- SWITCH 3 B
remain 6 lines unaccounted for? Will it not run if I don't
get that fixed? How can I fix it? I guess with some super-
special crimp tool I could make one, but what if I don't
have such tool? Get one? I know how to use a soldring iron,
so would consider that. May be I should use a cheap dead
chip just for the legs, I don't know.
Thanks for your help.

PS: I opened up one of the core memory board-sandwiches and
made a few photos. Amazing stuff. Will put those up on my
web site soon.
