Thank you very much for doing that! Those prints were one of the main missing
PDP-11 print sets.

It looks good to me.
I have an ADV11-A that I would like to use in a Q22 RSX11M+ system. The ADV11-C will work in a 22-bit Bus system from what I understand but the ADV11-A was made for 18 bit Bus systems. In the OEM Micronote book, Note 5, it states:
Any device which uses backplane pins BC1, BD1, BEl, BF1 or DC1, 001, DEl, OF!, for purposes other than BDAL18-21 is electrically incompatible with the 22-bit bus and may not be used without modification.
Further down it lists the ADV11-A as a device that does not meet the requirements for a Qbus 22-bit system because:
ADV11 (A012). A/D Converter. (Use of BC1 for purposes other than BDAL18)
When I look at the Board connector B pin C side 1 (component side) the BC1 pin is tied to ground. Several other pins are also tied to ground on that connector such as BC2, BJ1, and BT1. Other than BC1 which is BDAL18 being tied to ground the pins BDAL19 (BD1), BDAL20 (BE1), And BDAL21 (BF1) are all not connected to anything. This also matches the field engineering print for ADV11-A (B-TC-ADBV11-A-1) where BC1 is shown tied to ground on page 21.
So it looks like if I simply cut the trace between the BC1 finger and its connection to ground on the board it would become Q22 compatible.
Is it that simple?

The formal DEC name is "prefilter" (since the air that comes in here goes
through the cards, and the air blower, and then through the absolute filter
on the way to the pack), and the metal thing that holds it on is the "frame".

Here you go:
pictures and all the dimensions I could think of to measure. (I didn't bother
with the hole locations, since you can get them off the drive.) The little
hand-knob-bolts are DEC standard (used elsewhere too).
My restored RK05 drives are missing their rear air filters (the ones that cover the back of the card cage). I would like to fashion some sort of replacements. If anybody here has access to drives with the original filters, I?d really appreciate a few photos so I can see what these looked like and how they were put together?
I have now scanned the MP00574 / KK11-A printset I have received.
Hope the quality is good enough.
BTW. I am looking for the H8822 over the top connector. I just ask here in
case anyone has a spare. Otherwise it wouldn't be that much of a hassle to
make my own.
I do have the H8821 as a trade in case that is of interest.
Hello Plamen -
I use the SCSI controller that is built into the MVME177 transition module.
No, when I RESET the system, I just press the
RESET button on the processor board - usually
when it is hung with my software. On this
system, I only code in 68K assembly and so I do see the "occasional" hang :)
Is the "SCSI reset option" part of the 68K/BUG RESET command?
In my documentation - and I easily may not have
the latest documentation - I only see RESET
options to force a COLD or WARM start on hardware RESET.
The documentation that I have also cautions:
"...may cause the disk controller to be out of
phase with respect to the disk configuration
tables in memory", which certainly makes sense.
However, I do not modify any of those tables from system default.
I appreciate your input.

I've got a fellow with a stock of Teac FD235J (2.88) drives and about a
dozen bare Teac FC-1 SCSI boards.
I'm trying to gauge interest--I don't think he wants to sell them
onesy-twosy, but I'm willing to act as intermediary for single-unit
purchases if there is sufficient interest.
