Hi,
I've had a very dead DEC 350 in the shed for a while now and I've just
had a look at it, there are a lot of chips on it I can use.
But before I give everyone here a heart attack, is there any chance of
rescue? When I turn it on the 4 numbered LED's come on immediately, as
does the green DC light. Then nothing. Not a blip.
I tried removing all unneeded cards and still nothing. Is this thing
absolutely dead? Or can it be saved.
Also, is there any information for the three LSI-11 chips on it -
pinouts etc? I haven't been able to find anything about them anywhere.
Perhaps they remained proprietary to DEC. I'd like to see them out of
curiosity, and if the 350 itself proves to be completely dead I'll see
if I can wire them up on some prototype board and have a play around.
One chip is labeled (perhaps it's a FPU, I don't know)
DEC 304 E
21-15542-01
6436-40
I 8352 (that looks like a date code)
The other two have two dies each (which I guess is the processor itself)
IC 1, Left (closest to pin 1):
DEC 303E
23-001C7-AA
6319-29
8348 TIWAN (date code again)
Right:
evidence of a label exists, but it's unreadable
IC 2, Left:
DEC 303E
23-002C7-AA
6587-03
8425
Right:
DEC 303E
23-203C7-AA
6638-10
8422
there is also some print on the ceramic itself
IC1:
57000001A1
and a date code
IC2:
57000101A1
date code
Any information about these chips or the DEC Pro 350 is appreciated!
Thanks,
Alexis.
