an adapter cable to go from a 9-pin male (shell;
female pins) to a
15-pin female (shell; male pins)
Sigh, shouldn't try to type when I'm this tired. Female 9-pin (to plug into
the BA11-D) to male 15-pin (for the DD11-C/D to plug into).

*nod* I'll put the system aside again for awhile. But if I come across a
DD11-C or D I'll go back to work on it.
In the "Go to Unibus hell" category I DO have a DA11-F Unibus window. It
has the 9 pin power plug and could go in this box. More horrifying, it
can map a portion of one Unibus onto another so in theory I could plug
it in, wire into my pdp11/24's Unibus, and map the memory from there
onto the 11/05, then boot RT11. Hm. I wonder if I could then map over
the I/O page and access the RL11 on the 24.
And for real fun what would happen if I enabled the KT24 Unibus memory
map.....

I understand your frustration, as I've spent the better part of a year
acquiring and fixing an ME11-L and associated board sets trying to get
my short-box 11/05 up to a full compliment of memory.
Perhaps you've already considered this, but an alternative that just
makes the problem "go away" is to get yourself a Unibone.? Not period
correct (and not core, which is what motivates me), but super useful and
can emulate as much memory as you need.

Hm. That is an idea. Technically I'm just wanting to get the thing
working to see if it works, so a Unibone would be reasonable. Now where
do I buy one/a kit/whatever.....

Hi, I have Joerg's Unibone bare boards available (and others listed at
https://retrobrewcomputers.org/doku.php?id=boardinventory#dec_digital_board…).
Feel free to contact me privately if interested.
Thanks,
Todd

New subject: Plessy core memory - UNIBOne Info
You can contact Joerg at his site http://retrocmp.com/contact? For email see the UNIBone -
Get One Page http://retrocmp.com/projects/unibone/283-unibone-getting-one
A fellow on the VCF DEC forum tried to contact Joerg about a UNIBone recently and said he
had better luck using the contact page on the web site.? You can also take a look a the
Google Group for the UNIBone and the QBone (QBus version).
If you're not phased by CPL programming and surface mount IC then I'd say go for
the board from Todd (I've bought boards from him before, he's good).? If not then
you might want a kit from Joerg. The Get One page lists kits for ?170 or assembled for
?260.? In either case you have to supply your own Beaglebone Black though Joerg might
still have some for ?60.? I bought an assembled QBone and then later two QBone kits form
Joerg.? His work is also good. I just finished one QBone kit (assembly - testing is to
come) and it went well but the kit board (both QBone and UNIBone) come with all SMD items
installed and the two CPL's programmed so is mostly easy through-hole soldering.? The
trickiest part is the connection for the BBB.
Here are the build instructions -
