Found during cleanup, a RKV-11 controller.
It's a metal box, similar to a PDP-11/03.
It contains a 4 slot backplane and 4 cards.
One card has at the top 2 Berg connectors.
Box has no front.
Assumed to be working, as it was a shelf spare.
If interested, make an offer off list.
If only the cards and/or BP are wanted, I can disassemble the unit.
Regards,
Ed

Hi Ed,
It'S QBus, I saw.... So my interest is not *THAT* high :-)
If you don't find someone to take it, you can bring it with you.
Best wishes,
Philipp :-)

It is an RK-11D with a QBus converter.
RK11D for
Unibus with a converter in front? Is the converter general purpose? That would increase my
interest...

Indeed it would, but the M7257, is replaced with a M7268.
(which has 4 berg connectors rather than 2 as I mentioned in my
initial post).
The M7257 is the 'Bus Control Module' while the M7268 is the
'RK-11D to QBus adapter.
What you would like to have is the Qinverter made by Able (if
I remember correctly).

The RK11D contains: M7254, M7255, M7256, and M7257 in a hex-height
backplane that fits well in a BA-11-type chassis (expansion BA-11, or
11/34 or 11/24 or 11/44 CPU enclosure, etc)
The RKV11D contains: M7254, M7255, M7256, and M7268, on a quad-height
backplane typically mounted in its own "11/03" type enclosure, that
interfaces to the host via Berg cables back to an M7269.
The RK11C/RK11D use a BC11-A (Unibus) cable to talk to the first
drive. It plugs into the hex-height backplane.
The RKV11D uses a pair of 40-pin Berg cables (70-09026-00) identical
to what the RK8E uses. Those plug into two 40-pin connectors on one
of the RKV11D modules (M7268) and get into the drive backplane via an
M993 paddle card.
Here's a module list of all the relevant cards:
RK11D
M7254 - RK11 STATUS CNTRL
M7255 - RK11-D DISK CONTROL
M7256 - RK11-D REGISTERS BOARD
M7257 - RK11-D BUS CONTROL
vs
RKV11D (BA-11N)
M7254 - RK11 STATUS CNTRL
M7255 - RK11-D DISK CONTROL
M7256 - RK11-D REGISTERS BOARD
M7268 - RKV11, RK11-D TO Q BUS ADAPTER
RKV11D (Qbus host)
M7269 - RKV11 CONTROL (16-bit DMA only)
To answer your original question, the M7269 incorporates elements of a
"Qniverter", but is not specifically a generic Qbus-to-Unibus device.

New subject: Multitech MPF1 Plus. Documentation.
Hello all,
I have been a member of this group for a long time and have great respect
for anyone trying to preserve early computers.
I have been very lucky to buy an original Multitech MicroProfessor Plus. It
came with I/O, Eprom and Printer Boards.
The problem is "No Documentation". I have done all the usual places and
written a polite letter to Multitech, some weeks ago, but have not had a
reply.
Can anyone help please?
Kind regards and season's greetings to all,
Richard {UK}

Just curious which MultiTech you wrote to... there is this MultiTech,
http://www.multitech.com/en_US/
which is most definitely not the one that built the device that you have.
There was another Asian company called Multitech, which later became
Acer... and I believe they are the folks that built the device you have.
http://en.wikipedia.org/wiki/Microprofessor_I
Just wanted to make sure you were going down the right path... the two
companies were very often confused (with each other).
I used to work for the first MultiTech, here in MN, USA.

Not really!. IIRC 3 of the 4 board in an RKV11 box are the same as those
in an RK11-D. the other one (which has the Berg connectors to the 2 other
boards I mentioned) is specific to the RKV11. It is not a RK11-D +
DW11-B, and you can't trivially turn it into a unibus controller.

Hi Al
Digging in my pile I found the chapters I through VII
of "Build a Microcomputer".
I seem to recall someone asking about these. I'm
not sure if there was anything after VII.

Hi Dave,
I got hooked on these when they were the new thing to compete against CMOS.
I was working in geophysics, and they were the rage for fast ffts and seismic processing.
Later, had a graphics box called SUPERSET that was a graphics supercomputer (1982) that
executed a 48 bit a=b (op) c instruction set in a single cycle. Sortof like a precursor
to the DSP.
All 2901 based, in a microwave oven size box, and wow what a toy.
It was Ian Hirscholn's company, the author of PLOT3D, later bought by SAS.
Fond memories of the old days...
So heck, Im very interested in homebuilt CPUs. Even to cheat via the FPGA route, or not
even get out the wire wrap gun but do it all in modelsim.
I ramble.
Cheers.
Randy

I have an AMD book "Build your own AM2900 computer" with
samples and so on. It's a binder. Original
AMD. Saved that from scrap in my university. Is that a common piece? Or is it something
important
that has to be scanned?

Hi Ed,

Yes, the RKV11 is Q-bus (aren't all xxV11 options Q-bus). There also
should be a pair of dual-height boards that go with it, linkled up with
ribbon cables (2 calbes per board, IIRC). One goes into a Qbus slot (the
RKV11 backplane is custom, not standard Qbus), the other goes into the
interface slot of an RK05.
I have one, but AFAIK they are not that common.
