As many of you know I have been trying to finish organizing my Unibus parts
and finish building several systems for years. Other than time and my
health I don't have enough space. I would like to sell, at reasonable
prices, all of my q-bus parts which include 400 - 500 boards, about a dozen
boxes, and a lot of spare parts. I have BA11-M, BA11-N, BA11-S and a few
BA23 boxes left.
If you have an original 11/03, I have a dozen or so H780 power supplies,
which are very hard to find. They are also used in the Vax 11/780 front
end, the
RKV11-D and possibly a few other items. I can test them if I have time, but
that might take awhile.
I'm also taking offers on some of my 8-E and all of my 8-A items. I will
entertain offers on the VT14 and all of the PDP 14 industrial controller
parts.
I have a few Vax 3000, 5000, and a few others along with parts including
memory.
Those of you who have been here know I have a ton of DEC and
DEC-compatible parts, but no one has seen everything. I have brand new
disk heads, tape drive heads, alignment packs, and literally tons more. I
went through over 50 backplanes a few weeks ago looking for a few specific
ones.
Some Unibus items are also going. Probable some 11/05s, 11/34s, 11/83
and/or 84s and a lot of options and boards.
So if you need or are thinking about DEC items, feel free to send me a wish
list off list.
I prefer phone calls and will send my number upon request. I was never
great at typing and I'm getting worse.
Oh- I also trade for US and foreign coins and currency.
Thank, Paul

I do have an MDB Q-22 backplane, with no fan assembly or

with cooling, power supply and space for an 8" hard drive
would make a nice package to drag up to the VCFMW this fall.
A BA23 seems like it would be exactly what I'm looking for!
I cobbled up my own power good and bus reset circuit that
never worked quite right, so having the DEC original circuit
would also be great.
Do you have what I'm looking for?

I have a few BA23s left, and a few which need TLC.
Are you in St Louis? I'll be in Springfield in July.

Yes, St. Louis area. I don't know what TLC level you are
talking about. Not too interested in ones with bad power
supplies, but if they just need some serious cleaning, etc.
then that would be fine.
Let me know.

Where are you located? I wouldn't mind a BA11-M box for my 11/23-PLUS.
I have a feeling shipping would be pretty high for one of those.

Hi Peter,
The BA11-M is the 4 x 4 box for the 11/03, and I would not recommend it for
an 11/23 or 23+. The BA11-SA would be my pick.
I can ship them. Where are you located?

Hi Adrian,
I should have the G 8016 and G8018, and both front panels if you need one,
but no way to test them right now.

The RKV11D was a weird little device, but it really made sense at the
time. Technically when the 11/03 came out it was a 16 bit only device,
small, and I think DEC realized they had no hard disks at all for it
once it got to marketing. I mean they sold it as the 11V03 with the 4k
memories, maybe a 16k MSV11-CD and an RX01 floppy drive but that was
literally it for support.
To give it SOMETHING they did the RKV11: They took the 4 slot RK05
controller from a Unibus system, built the bus interface board to
support 16 bit Q-Bus and used the box to box interconnect cables to
connect it. Quick, dirty, and got them a drive. Then they got the RL01
shipping, tried putting it on a card, and realized all the analog
circuitry needed on the hex height RL11 was not going to fit on a single
Q bus card. And thus came the CD interconnect.
Only problem was the BA11-M was not going to fit that, so they dumped
the BA11-M for the N, a 9 slot backplane with 18 bit support and CD bus
so you could install the RLV11 cards. As for the 11/V03's they are
pretty, make a good end table, but really fell off the rails for
support, the only thing you could do was run a RXV11 system, get a
RKV11, or toss it all and go to a BA11-N.
Fun times. (Disclaimer, I have an 11/V03 that had the above path taken.
Going to RL01's instead of the RX01's was a game changer for 4 user MUBasic)

Hello,
Do you by any chance have Vaxstation 4000 models or motherboards at hobbyist prices?
Or anything like an inventory of your Qbus boards?
Other than that, I'm interested in a BA23, disk controllers (RQDX3 or SCSI),
DELQA/DEQNA.
Also a KJD11-B (m7554) and some PMI memory for it, so I can run PDP-11 diags on Qbus
devices.
(The field service uvax II diagnostics on TK50 are unobtainum.)
thanks in advance

Hi Jonathan,
I have the RQDX3, DELQA or DEQNA, and the M7554. Do you have a part # for
the memory? I'll check for the 4000 parts, and I have a few BA23s
