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.
IIRC, the LEDs are turned on by a hardware reset, and then changed in
state by the processor. So all on implies that the processor isn't
running. Maybe it's being held in a reset state due to the power OK
line
from the PSU or something.
The reset line for the F-11 (just looked it up, it's not an LSI-11)
would be useful to know now. I'll continue looking.
But even then I don't have a proper monitor for it! I've got a 21" RGB
for my VAXstation 4000-60 but I doubt it'll handle the resolution of
the 350. I've got the video and keyboard cable for the 350 however. I
won't try it until someone gives me the all clear.
Thanks,
Alexis.
