Yes, it is red and has a small reader on the front plate. The machine
seems to be complete (expect the disk drive that is missing the removable
platter assembly/heads).
I can make some pictures these days.

This is very similar to the slides on the BA11 (-11/20), which also had the
rotation, so I suspect they were all this way (i.e. there no early versions
without, etc). Having said that, if anyone has a -D with something else,
please send me an image so I can document it.

Probably the easiest option is to buy a set of those C-230-S's; the mounting
holes on their inners match the locations of the swage nuts on the BA11-K
sides, so it's straight simple bolt-in. You'll lose the rotations option,
though.

Hi,
I have a lot of dmk images and tried to convert them to imd with dmk2imd.com.
Trying with on of those files:
http://oldcomputers-ddns.org/public/pub/rechner/eaca/genie_3s/my_genie_3s/i…
The conversion was fast and told me:
Tracks:80x6528 DSSD
Assuming 500kbps data rate.
But when I write the *.imd to floppy I get only 40track and that is realy not good. :-(

Do you have the inners? The only -D inners I know of are the kind shown here:
http://gunkies.org/wiki/BA11-D_Mounting_Box
and if you have those, you're in luck; the outers from a still-available
Chassis Track unit are perfect replacements for the original outers. Kinda
pricy, mind, but at least they're available.
If you have a different inner, I'd love an image, so I can see what it is,
and document it.
If you have no inners, kinda ugly. You can buy that CT unit, but you'll have
to drill matching holes in the inner - and you lose the rotational capability.

Like the lower picture:
http://gunkies.org/wiki/BA11-K_mounting_box
there? I'm guessing that's zinc-plated steel.
Alas, I don't know who made those (may have been DEC themselves), or a source
for them. _But_....
I have some Chassis Trak outers which are almost compatible. (I say 'outers',
but actually many slide sets are 3-part; there's an outer which bolts to the
rack, an inner which bolts to the mounting box. and then a third piece, a
'middle' I guess we can call them. Sometimes the middle and outer can be
separated, with a safety latch you have to release - but I think I recall
seeing one set where you can't extract the middle mrom the outer - at least
not out the front.)
Anyway, the silver inners do fit into the track in the middles of those CT
units - all except the two wheels at the inside end of the inners! Too bad,
because I have no use for these outers, and would be happy to hand them over
to you.
The other possibilithy is that I _might_ have a spare set of the silver
outers. I have 2 sets of the outers (2 left, 2 right), 4 of the special pivot
bolts - but only one set of inners - at least that I can quickly find. Let me
have a look around, and see if I'm really missing the inners - if so. I might
be up for trading you a set of outers for something I can use.

Is it in a BA11-K (as suggested by the Subject line), or BA11-D? (-11/10's
came in both, for the 10-1/2" box.) The -K has the power supply on the end,
the -D down one side.
What slide hardware, if any, do you already have? (Many come with the inners
[the part that bolts to the mounting box] still there, but the outers have
been discarded.) If you've got the inners, you're home free; I can give you a
General Devices 'Chassis Trak' part number that will provide working outers
(although you'd probably have to modify the locking hole for the lock to
work).
If you don't have the inners, I'll have to go look and see what can be
done... (The original DEC inners are, AFAIK, now unobtainium.) Oh, and if you
do have inners, I assume they are the earlier, grey-coated ones, not the
later silver ones?

We may have found someone at least on the right continent ;)
For those interested, he sent a pic (but haven't looked at it closely to see if the -11 is even in there):

There were plenty of real PDP-11?s that found their way to Russia.
Often through front companies in say Vienna.

This for sure isn't a PDP11, it would be an "ELEKTRONIKA 60" I think.
This is something like an 11/23 but with metric Connectors, PCBs are a
little bit bigger as PDP11's.
I do own such a beast, that's a picture from the CPU:

Other pictures are in the same directory (directory index is allowed).
..it's running RT11 from a 8" RX Floppy clone...

I used to have a SCSI interface version of that drive type, I made backups of my Mac Plus (I think it was) hard drive. Since I don't have it currently, I believe I gave it to a friend along with the rest of my Mac Plus peripherals. I don't recall the capacity of my specific drive, but it used a "data cassette", which had a notch in the tape case to prevent use of regular cassette tapes.
