I have not tried testing mine and I was not one of the bidders.

They are so uncommon that I never expected the boards to come up for
auction so I haven't been looking for them.  I have a long way to go
before I'm likely to even take a stab at them - like probably not this
year.

The goal is to get a working KA11 by 2022 though.  I am still clearing
the queue to make the KA11 a focus for 2020 or 2021.

Must be two such people, though - I was neither of the top two bidders.
Odd for there to be so much interest in them.

I was one of the bidders.  I have a KE11 backplane and it is populated.  I just 
wanted some spare boards.  You don't see these boards that often.
I am hoping that a backplane would appear too.  The seller seems to have some 
early pdp11 backplanes.

No idea.  I have those boards in my box of KA11 boards and since they
arrived together, I expect I have the right backplane in my BA11-C,
but I am also surprised to see such interest in just the boards.
Perhaps someone has a broken KE11-A and doesn't want to/is unsure how
to do component-level repair.

KE11-A craze (Was: Current MANX location)

Speaking of KE11-A's, does anyone know what's behind the bidding wars on
recent eBay KE11-A component board listings, e.g.:

  https://www.ebay.com/itm/372685033144

AFAIK, the boards (a complete set is an M7210, M7211, M827, and two M234's)
are pretty useless without the custom backplane, so do some people have such,
or do they not know they need the backplane, or what?


I do have a couple of BB11's (they came in an old custom interface I bought),
and the KE11-A FMPS includes the backplane wiring, so if I were interested
enough to devote the time to wiring a replacement backplane, I could probably
get one running, but they aren't _that_ interesting...
