I am selling an Atex PDP-11/34. The computer has: J11 CPU, 11 MB RAM, 2
BA11-LE expansion chassis, a second backplane, an SMD disk controller and
LAN hardware.
Items are all untested, sold as-is.
Local pickup is preferred, but I will consider shipping freight.
Please make an offer on the whole machine, or any piece of it.

So an RX02 can be jumpered to work with the non-DMA RXV11; but the DMA RXV21
can't be configured to work with an RX01. Which of these two is a more
interesting/useful thing to be able to do?
People at MIT used to theorize the existence of a virulent biological virus,
'Honeywell Brain Damage'; I wonder if there's a DEC mutation?

Those used to be fairly common on eBay for not many dineros; I only see
one moderately expensive one at the moment, though. I'd definitely go
this way, though - maybe Paul A has one available?

I have a Dilog CQ-1610 serial line card (16 ports!) that I'd either like to
sell, or at least put it in my backplane and play with it since I have a
copy of TSX+
:)
But I can't find any info, especially the DIP switch settings. All I see is
"emulates a Unibus DH-11" but that is not even close for hardware/layout.
Any thoughts?
thanks
Charles

I'd like to know too. I never could quite understand just what Marvin
The Martian said. " The *** 32 * **** um *space ** xx ** later *, :)
Unsurprisingly the DEQNA card in my PDP-11/73 is quite unstable and
results in 2.11BSD panicing. Is there anything that can be done about
this? Other than unplugging it that is... I don't think there very much
broadcast traffic making its way to the PDP. It's usually when I'm
transferring files.
If not, does anyone have a DELQA card they would be willing to part with
(preferably in the UK) for a sensible price?
Thanks,
Aaron.

I ran this ad back in 2015, will try again :)
I was going through my board collection and found three PDP-11 boards I've
never used in years and don't see a foreseeable need.
No idea of condition, but they're visually clean and neat, stored in
antistatic bags.
The serial cards came out of my working 11/23+ but I've not tested them
(since I already have a 16-line card and only 2 terminals).
I have (one each):
M7957 DZV11 Quad height 4-line serial card
M8053 DMV11 "Microprogram Control" synchronous controller card (looks
like it was intended for networking with 56k modems)
Dilog CQ1610 16-line serial card.
Make any reasonable offers. + shipping from US zip 65775.
thanks

I have a PDP-11/23+ with two RL02's in a corporate cabinet but no floppy
drives. Also an RXV21 (M8029) card.
My PDP-8/A has RX01 drives, and I was hoping just to run the cable over to
the -11 when I wanted to use floppies on it.
But after some searching, it appears that the RXV21 will only work with an
RX02 drive...
Just wondering what my options are for hooking up any kind of floppy drives.
I could sell the RXV21 and buy/trade for an RXV11 (M7946) instead, to use
with the RX01 in the other rack.
Or look for an RX02 that won't break the bank - but that won't fit in the
corporate cabinet. I do have another cabinet but it's got other rack-mount
gear in it at the moment.
What about smaller drives (RX50? RX33?)... can those be interfaced to the
11/23+ Qbus?
Other thoughts?
thanks
Charles
I? remember? in '79? ?a? KSR? Diablo? was? ?the? dream? KSR? printing? terminal? and? ?cost? like? ?3? grand? Oh? how? we? used? to? dream of having one of these? back then!

I've given a couple of the Diablo KSRs (that's what the Hitypes with the
keyboard were known as).? I didn't care for them much--no immediacy of
sound and keypress--the two seem unrelated.
Daisywheel printers are incredibly difficult to get rid of--nobody wants
to pay shipping.? I got rid of the last one by throwing in a complete
system with it.? Still have a NEC Spinwriter mouldering away.
