Just when I thought eBay couldn't get much stupider...
I went out to see if I could find a current going price for
PDP-11 Pedestal Boxes as I have a couple I would like to
cull from my collection. I came upon this:
DEC PDP 11/23 - BC needs Power Supply Repair, NO cards, Vintage DEC History
$900.00
If it has no cards, what makes it a PDP-11/23 other than the paint
on the front cover? Dead PSU? Looks like a $900 backplane to me.
And that is making the assumption that the backplane is actually
usable. :-)

I've been digging through a few shelves of backplanes looking for a
specific one for a listmember. Along with the DD11-CK and DKs, I found a
RK611 and RH11. I probably have the boards for both. Any interest?
Also found a few DDV11-D which I think is a 6x9 hex qbus backplane, but
it's been a while.
If you need any backplanes (11/84, 11/44) or options (DR11-B, etc) now is
the time! Also a lot of core memory and backplanes.
Please contact me off list.
Thanks, Paul
Hi all,
by surprise I got a Tadpole Sparcbook 2 some time ago.
Sadly there seems to be almost no documentation available in the net for
a Sparcbook 2, neither a technical/service nor a user manual, only for
Sparcbook 1 and later models.
I do have the following issues:
- the battery pack is missing.
I found two ressources, e.g. the CHM - but none does have any infos
about the battery pack
- The external power connector requieres 18V - no problem
- After connecting the fitting power the Sparcbook does power up, the
display is lit and the unit is trying to boot from the internat SCSI
disc. Nevertheless the boot process is failing this is a good sign.
- after trying to reboot the unit will be almost dead. While pressing
the power on button the LEDs on the left upper side of the display will
be lit shortly, but nothing else will happen.
- trying to reboot an power on the same as above will happen
If I'll keep the unit several weeks/months unpowered the unit will power
up again - but of course will be stuck again while trying to boot from
disk and the same semidead issues as noted above.
I'm suspecting the TOD chip/battery is deads or are there any other
sugegstions?
Up to today I didn't have a look inside of the unit ...
Does any have the manuals hidden in theirs shelves?
Best
Andreas
