Does anyone know what the QED board (4th image) in this eBay lot:
http://www.ebay.com/itm/322414100718
is? The large chip looks like a J11 chip. However, the only QED PDP-11 board
I found mention of online is a high-performance hex board UNIBUS processor,
the QED 95.

Perhaps a silly question but have you poked around local social media for a local unix group? Or a local craigslist ad for someone to borrow a key? I wouldn't think they'd be thst uncommon although admittedly I also stopped/paused a project for similar lack of results a while back (much different system though).

Ah, so you actually had some prior knowledge that helped in working out that
puzzle, that that's what's happening here! :-)

Its literally Christmas for me today.
I came into physical position of a well optioned-out SPARCserver 1000e,
accompanied by several SPARC Storage Arrays.
I'm doing a physical review of the 1000e, i.e. re-seating boards, physical clean
up, etc. And reviewing all the appropriate hardware documentation, still
available, directly from Oracle.
Anyway, on the front of the case is a (4) position power switch (i.e. standby,
on, DIAG, lock), that is unfortunately not set to the on position.
Hoping that someone out there either has a key that they will part with, or,
knows of another (presumably Sun) key that will work in the 1000e key switch.
Thanks for looking,

Hi CC folks:
Been trying for several years now to find the vital parts I need to
get a Nova 3/12 from my old Univ. up & running. What I do have now is
the chassis with PS, front panel, CPU and FPU boards, some of the
documentation, and, hopefully pending, a disc drive (not sure if it
has controller). Most of all, of course, we badly need Mag or MOS
memory, plus I/O boards/peripherals. Have posted on "vintage
computers" several times and also contacted a DG specialist but so far
no success with parts. ANY help in getting this thing going before,
at pushing 70, I get too old to ever see it run even a simple routine
or ancient game, (or care !) would be very deeply appreciated!!
Please eMail: firesweep "at" verizon "dot" net if you can help or have leads!
regards,
Roger A. in NY

The M19 is 60mA at 100VDC... takes a bit to pull that relay.

Yep. That's all I have in my own pile... (33 and 35).

Gee, Tony, why don't you tell us what you _really_ think! :-)

Hi there,
I've got a couple of DEC QBUS boards (including a quad SLU) for which
configuration is set by wire-wrap jumpers. I don't have a wire-wrap tool,
and have found that trying this by hand without one is not workable.
Has anyone come up with a clever way to permit reconfiguration of these
boards without semi-permanent changes? Or, alternatively, what wire-wrap
tool would you recommend?
Thanks!
