PDP 11/34a - $600 - BA11-K chassis, 248KB MOS, M7856 serial, DU686 ESDI card,
DELUA network card, and Pertec controller. I'll be powering this up at the
show to verify it's still working, but it lived in A/C in a bedroom on the
second floor since I last turned it on in 2011 and booted
Dual 900mhz CPU, 4GB of memory, service processor card, includes rack rails.
Tested working with OpenVMS 8.4.
They all include at least one 36gb or 72GB hard disk. Presumably they'll take
anything that's SCA80, but the sleds are special.
I have 6 of these units.

Funny, there's this 11/23+ (BA11-S style) I bought from Pavl Zachary many years
ago, it's been a near-constant companion through all of my moves and most of
the VCF Midwests. Despite the bouncing, banging, and shuffling, it's always
worked. It ran 24/7 at my home for much of its life, without
, it was fluctuating.

As LED 9 is on (sorry for not being clear), then the CPU is active. That’s a
good sign
Both green LEDs are on. They're ALL on.
This is a failure of the DC Power Up/Down circuit - See page 3-10 + 3-53/54 in
June 83
Service Manual. If the components in this circuit (capacitor) are out of spec,
then this may be the cause.
Congrats on picking it up. I was tempted to bid
So the DSD-440 I got at VCF is completely unresponsive. All of the LEDs are on
and never go out, which is bizarre - they are supposed to go out in 1/10 of a
second after power on.
I tried disconnecting everything but power to the card, and it still lights all
LEDs. No jumpers that I
Never mind. The 11/23+ boots from a SD-IDE+IDE-SCSI adapter combo and I had
inadvertently bumped the card and ejected it. Nothing's wrong.

Hi folks,
I recently acquired a DSD-440 drive and purchased its accompanying controller
on ebay. The controller is configured at defaults according to the manual on
Bitsavers. However, unless it is on the bus by itself after the RAM cards, it
halts the CPU at location 270.
Here are
The VT52 and DECdatasystem are spoken for. Please, no more offers.

I will be selling my DECdatasystem 534 and VT52 at the show. Cabinet rack,
72x24x26.11/34a, 32kW of core and A/D+D/A cards. System runs fine and
drops to a console prompt, and passes all the diags I've been able to throw
at it. I've restored all the foam filters and the cabinet was pressure
washed
