Yes, the 3 bays in the center are a PDP-15. (The indicator panel at the top
of the center bay is the one for the PDP-15 CPU; you can see it here:
at the top of the 'PDP-15' section.) The Unichannel 15:
is undoubtly there to drive the RK05; I don't think there's a native PDP-15
controller for that.
> There is an 11/15
??? Is that a typo for 'PDP-15'? The -11/15 looks just like an -11/20
except it only has 16 address switches, not 18 as on the /20. (The front panel
shown there has an OEM-specific re-paint; I couldn't quickly turn up an image
of a DEC /15 front panel.)
If anybody of you has been looking for a Bendix System or a CDC 160 console and has deep pockets: That's your opportunity ;)

Not affiliated with the seller. Just saw the listings - can't believe that such cool systems are still stored in some warehouses in the U.S. for business purposes ...

The "Spare Module Handbook" lists:
Does _anyone_ actually have an MX11? Any documentation would also be welcome;
all I've been able to find out about it is a listing for the addresses of
Anyone need/want a couple of these? Someone has a group of 5 for sale on eBait
(#184317666245), and I want a couple, but not _5_. The seller didn't respond
to a request to split up the lot, so I'd like to go in with a couple of other
people on the. Any takers?
to fellow readers in Germany and surrounding areas:
HUGE 9406-F2, 300?, pickup in Heidelberg, Germany. Might be a Multiprocessor-Machine.
I?m not related to the seller. Have seen this by chance.
I requested more photos to see what machine it is. Would be very sad if it will be scrapped. I can forward the additional photos as email on request.
Can someone check to see if a RQDX2 used the Western Digital chips to
interface to MFM drives? Reason I'm asking is the MFM emulator can
identify an RQDX3, and also a Pro/350 controller but this particular
RD52 I have (which was verified by me to run Digital Mumps) is reading as:

An update on keyboard storage, which I asked about here last month.
I ordered some USPS Large Flat Rate Priority Mail "board game" boxes.
This is a size not usually available at the post office and come 25 in a
pack. They are a good size for mailing (and I am glad that I ordered
them so I can use them for that), but I don't think they work for
keyboard storage. They are so much larger than the keyboards that I am
storing that lots of packing material is needed so they don't move
around. Also, they are designed to be sealed and shipped, so there isn't
a convenient way to open them once they have been closed.
Next, I ordered the Uline keyboard boxes. I had to get 25 of them and
they are not free ($2.70 per box plus tax and shipping). They can be
open and closed. They are a much closer to the size of a keyboard
(surprise, surprise!) so not much packing material needed, but they are
slightly smaller than a Sun Type 5c (as well as Axil) keyboard and
needed to modified for those two. No modification needed to store a Sun
Type 4 or CompuAdd Sun-compatible keyboard in one. I haven't tried a Sun
Type 6 yet.
To anyone in the Seattle area that need keyboard boxes, I will probably
have 10-15 of them once I get all of my keyboards packed. If you would
like any, let me know.
