He is most likely speaking of the SunRescue list. You can find it at

Come and join the fun :-)

What rescue list?

Well, there was a funny little program that would allow you to "remove DOS

such a non-bootable disk.

Isn't that uncomfortable?
I'd rather have a special hard-to-find mouse-pad. :)

Being a PET user from way back, I always liked the Commodore drives from
one particular aspect - they were intellegent peripherals. You didn't
bang on a couple of registers to make magic things happen (like on the
Apple), you communicated your request and it did what you asked or it
told you why it didn't work. The thing I did *not* like about them was
that they were scorchingly expensive. By the time I could afford a
PET drive, nobody cared anymore. I think my first 4040 was about $10
>from the university surplus.
I also liked the fact that the PET did not need boot disks. I saw that
as a major source of problems watching my friends sort through piles of
Apple floppies, looking for a DOS3.3 disk.

I've just sent EK-78032-UG, basically the 78032 User Guide
over to DFWCUG. You can see the gory details once
it arrives and they put it up.
In the meantime, from Appendix A, clock
period is variable from 25ns to 250ns
i.e. 40MHz to 4MHz. It specifically states
(somewhere) that the part will *not*
work down to DC.
The clock should be held in the high
and low states for 16ns each, so even with
infinitely fast rise and fall you cannot do
better than 32ns and stay reliable across
all parts and all temperature ranges.
Now if you are willing to restrict the
temperature range and hope to work
on just *most* parts, who knows :-)
Tweaking a MicroVAX II won't buy
you much. I doubt you could bump the
clock by much more than say 20% without
something going horribly wrong. And the
uVAX II is a fairly well balanced system:
the memory cycle is just about right for
the CPU (I think it works out that the CPU
cycle time matches the memory cycle
time - hence no need for cache).
So if you up the CPU clock, you need
to find some way to speed up the memory
otherwise you don't even see your
modest 20% gain.

I'm sure glad to see the list is back up, I originally tried the following
message on Tuesday. I still don't know anything more about the system.
Unfortunatly it's been raining really hard around here since Tuesday, so
the system is still sitting at work, and I've not really been able to
examine it.

I'm still a little shocked. I just found a working iPDS system, complete
with documentation and some software. Unfortunatly I don't think a lot of
it is still readable. I did get the system to boot and pass all
diagnostics.
I know nothing about these beasties, from looking at the doc's it's
obviously i8085 based with 64k RAM. It's got a single 5 1/4" floppy, and
it's in a case slightly smaller than a Kaypro II. In the area behind the
CRT is a storage area for two pods that each handle two different sizes of
PROMs, these plug into a hole in the right side of the case.
What on earth filesystem are the floppies? Are any kind of software images
available to replace the dead floppies? Is there any software to read and
write to the floppies from MS-DOS?
Basically the main thing I'm interested in is the systems ability to read
and write PROMs. I wouldn't mind being able to use this to support my DEC
hardware :^)

Well, by way of explanation... My trademark on the rescue list is to
say "Is she cute?" for ANY mention of any sister, wife, female
coworker, any female at all. Somehow I didn't think that'd go over
very well on this list. In spite of the unbelievably long off-topic
threads that occur here, this is definitely a much less "social" and
more "down to business" mailing list. ;)

Hi,
I have sitting on my shelf a PDP 11/34 working unit rescued from the recyclers. The system was operational when decomissioned. Caveat: no power supply. So the pieces or the whole are up for grabs, shipping costs only. I thought they may be of interest to the right people, since most of the boards were original DEC. I also have a CD-ROM full of DEC maintenance and service documents for the PDP series. Any interest in that, ask for details. Be aware that I live in Ottawa, Canada.
Here is the list of cards found in there. I am not sure it is complete, because I may have listed only the ones I could actually recognize.
PDP 11/34 CARDS
DIGITAL
M7762 RL11 U RX01 floppy disk controller
M7856 DL11-W U SLU and realtime clock
M7859 U 11/34 programmable console interface
M8256 RX211 U RX02 floppy disk controller
M8265 KD11-EA U 11/34A processor data paths
M8266 KD11-EA U 11/34A processor microcode module
M8267 FP11-A U 11/34A floating point processor
M9202 U UNIBUS connector, inverted
(M9192+M9292 assembled M9202 1" apart with 2' cable)
M9312 U Bootstrap and terminator module
OTHER
Dataram Corp U 256K DRAM board
The system was obviously well cared for and was not even dusty. The console board is the one that includes an Intel 8008 processor. The system case and front-end are impeccable.
I don't collect PDP equipment, but I hate to see a nice system go to the junkyard. At the same time, I need to make room for other masterpieces in peril.
Cheers,
Frederic Charpentier
