Yes, I have heard about about the BA11-S, though I
don't know if it'll
play host to the H9275 backplane.
It's essentially the same box as a BA11-N, and anyway the H9273, H9275
and H9276 backplanes have the same mountings.
I am a fan of neither BA23 box; the deskside one looks
a bit too much
like a rather large, rather generic deskside workstation PC, the
rackmount one, well my only real gripe is: "Why is it *beige*?"
Because it's not been painted a proper DEC colour yet?
Or at least, most of the ones I've seen are beige.
If they came in the
same "clean" white as the BA11 boxes
Hmm... they don't look white to me. Probably because they're a very
specific DEC shade of grey :-) But not beige, no!
DHU11 is UNIBUS not QBUS; the DHQ is the QBUS
equivalent.
I wasn't thinking quite right there, the QBus version is the DHZ11
(16-line serial mux), though it's probably fairly uncommon. DHQ11 is
only 8 lines.
I don't really plan on running an KD11 of any sort
in this system, nor
a KDF11; but I do want to try and stick with a QBUS only (no CD
interconnect at all) backplane. While I do miss out on some of the
older quad-width card sets (RLV11 and RKV11 come to mind), chances are
they wouldn't work with a KDJ11 system at all.
They do. Mine do.
