Click on the uPDP-11/93 link.
There is a simple page about the 11/93.
The only interesting part (?) is the
description if the DIP switches.
That's all I have on the 11/93.

Hi Jonathan.
Check out http://archives.decdocs.org
Click the link "print set archive"
There you find, among others, the Print Set of the 11/34.
The folder "manuals", down the list, contains all you need.
KD11, FP11, KK11, M9312, etc.
Especially look at the KK11 manual. It describes the step
you must do to install the cache next to the FP taking into
account the power distribution.
It works, I did this at home with my 11/34A.
BTW you need a special "over the top" connector to connect
one CPU board + cache + FP board .... Sorry, I do not have
a spare one.
Does an 11/34A with FP and cache become a "PDP-11/34C" ?
Good luck with the conversion,
- Henk.

Hello all,
I have in my posession, three tested, working, Rom 00 Apple IIgs machines,
complete with monitor, 3.5" and 5.25" floppies, keyboards, and mice. I am
wondering if anyone would like them, for a nominal price + shipping.
Before anyone misunderstands me, I am not asking for tons of money for these
beasts, as I realize they're pretty crippled (They had defective video
chips, and the ROM version doesn't allow you to run GS/OS). They do run
most Apple IIe sowftware, and could be considered as an accelerated IIe.
Not the best example of a IIgs, however, if you are looking for a machine to
complete your collection, they are available. Note that NONE of them are
the "Woz" variant.
I got these (along with several "ROM 01" and "Rom 00 upgraded to Rom 01"
IIgs machines) from a local school. I would like to save them from the
dump, and help the school out as well. Therefore, I will take offers on
these machines until Thursday 04/11, 11:59PM Eastern US time. ANY AND ALL
proceeds will be donated back to the school the computers came from. I
will separately notify the highest bidders that they have won....
Your chance to own a small part of Apple II history, and help out a local
school as well..
I will ship anywhere, worldwide, that the US Postal Service allows me to
ship, and I will consider shipping just a CPU (i.e., no monitor, or no
drives, or whatever combination you want), as it will cut down on
shipping... The units will be shipped from US ZIP code 01473, and to give
you an idea, a monitor weighs about 25 lbs boxed, and a CPU weighs (I think)
8 lbs. boxed... I will quote actual weights and shipping charges to anyone
who asks....
Thanks!

OMG... I was just smacking myself on the head about this earlier.
I have been hanging onto a previous email from a few months ago that
mentioned this fest. I just the other day accidentally deleted it (and of
course, since my email client removes anything older than 30 days from my
deleted folder, it prompty purged the email).
What wonderful timing for you to post the reminder... THANKS! (now, does
anyone know if the Trenton DMV is anywhere near the fest grounds? Maybe I
can transfer my fire department's trailer registrations to NF while I am
down there so we can stop paying reg fees every year)

Happened to notice they are 10Base2 (BNC connector and AUI interface

For what it's worth, you can get them refurbished from Plextor,
supposedly, for about US$95 for a SCSI cd-rw of some sort. That's
probably the best price I've found on them. The only reason I didn't
get one instead of the Sony drive I finally settled on was that they

Hi. I'm looking at an Amiga 2500, with a 5M hard drive, unknown ram,
a lot of boards in it (the owner knows as little about it as I do), and
no keyboard, mouse, or display. He wants $30 for it. He has a display
>from a Commodore Colt hooked up to the composite video port, and the
2500 will boot to a screen with hand holding a WorkBench 1.3 floppy shown.
Are keyboards as hard to find as it seems? That's the showstopper so
far. Is $30 reasonable for a partially tested A2500? Will the
kbd/mouse from the Colt work?
Aquiring minds want to know. :)

I have. It works as long as the block size isn't odd. Generally
any cd will take a block size of 2048 bytes, however, if the CD
is "bad" (scratched, or what not), a smaller block size (1 ;) may
help you get more good data at the expense of some speed. You
can also use the conv=noerror option to ignore read errors if you
really want whatever data you can get.
As somebody else mentioned, cat works too, but it doesn't have
an option to make it ignore read errors and keep going.
Otherwise, you're right, use mkisofs, or mkhybrid to make a
filesystem from some of your files, and then use cdrecord to burn
it.
There is another program (cdwrite?), but I don't think it has nearly
the same level of device compatibility, not to mention that the
number of systems cdrecord will build for is very impressive.

While it's possible that he's a bit put off being called

I am looking for some sort of service manual or something on two Power
supplies I picked up yesterday at Purdue Salvage. The first one is a HP
711A 'adjustable AC/DC power supply', which is fairly old and tube-based.
After plugging it in, nothing happens - no filaments light up, etc. I
haven't had time to go through and 'probe' it to see if the transformer
is still OK yet, that's my next step. If anyone has any info on it, please
drop me a line. BTW I've checked the fuse.
The second one is fairly new - a HC Power Model HC10-1A switching 5V,
200A power supply. I think it was manufactured in 1992, making it 'just
classic' as far as electronics go. I've taken it apart, and the line-side
smoother caps are charging up, so I'm guessing a control problem. I'm
going to try and contact Power-One (they aparently bought out HC Power)
tomorrow to try and get info on it. I would really like to get this
working so that I could try and use it for my new SSI/MSI (perhaps a few
PALs if necessary) minicomputer I'm designing. [Aside: If they'd only
give me some sort of course credit towards my BSCompE for doing this, I'd

I've recently inherited a Gould 9540 (8 MHz MC68000 CPU, Multibus) which
would appear to run some sort of UNIX variant (System III, if I had to
guess) I'd like to check it out, but the system sports a rather large
sticker on the back panel which states it was wired at the factory to run
on 240V.
Before I spend a lot of energy trying to figure out whether it's still
true and how to strap it for 120V operation, I thought I'd ask if anybody
knows how to tell, off the top of his or her head.

That's one cool station! As I recall it's something like 10 stories

be an Egghead store a few blocks from the station. I've still got the 14.4k

>Why is 212992 magic?
OK. I'm an idiot :-)
RT-11 has a limit on disk
size, and my (poor) recollection
is that this might be in the
region of 64K blocks (512 byte
block ... i.e. 16MB per disk).
This would be 16384 2048-byte
sectors. 13*16384=212992.
So my guess is that when you
use this RT-11 CD on an RT-11
system, you tell it to map partition
13 (and 14 etc. onwards to the end).
In which case writing an image
would be a breeze. Create your
ISO file system as a binary (ISO9660)
image file and overlay onto an
image of a full 650MB or 700MB CD.
Create images of however many
RT-11 "disks" you think you
can fit onto the end.
Determine where the next 16384 2048-byte
boundary is and drop your first RT-11
partition there, then keep overlaying
further partitions until the end.
OK. I don't know how to do this
on Windows 98 with the available
tools, so you'll either have to
do it on Unix (or OpenVMS)
or knock up a quick
tool in C for Windows.
Or you could ask Tim how he did
it (but I bet W98 was *not*
part of the answer!).

In Geos the whole OS was coded in 6502 assembler. Couldn't make an 8bit gui work with slowpokes like C.
GEM and TOS (as I understand) were partly host assembler (8088 or 68000) and part c. No commonality
under the hood at all.

Burning under windows is probably
not an issue - use something like
CDR-Win to make an exact copy
to an image file, and then burn that.

I don't know the specifics of RT-11s requirements
for the CD. I expect that RT-11 sees it as though
it were a hard disk of exactly that many blocks
(well 4 times the number of CD blocks because
of the 2048<->512 byte thing).
Many (many) years ago when I used an
LSI-11/23 under RT-11, we had a 40MB
drive that emulated 4 RL02 drives (or
some such). I don't recall if this
was done in software or hardware -
quite possibly it was a software driver
that came with the disk.
Why is 212992 magic? What do you do
to make this CD visible as 7 (or whatever)
disks under RT-11?
Essentially your CD is a stream of N
2048 blocks and is presumably seen by
RT-11 as such (at a sufficiently low level)
and then given meaning by some
software layer.
A typical method for generating
a layout with both ISO and
"other stuff" in logically separate
areas of the CD would be to start
by generating a binary ISO-format
file with just the ISO data in. The
first 64 2048-byte blocks (or is it
32?) are ignored by the ISO9660
standard - they are deliberately
not used.
Now create an empty image file,
the size of your CD. Overlay the
ISO image file onto this.
Now you slip the PDP-11
boot block in there and add whatever
else you need at the end in whatever
format you want. The ISO file structure
will be unaffected (so long as you tack
things on after its logical end).
What you need to find out is
RT-11s requirements in this area.
Actually doing this under W98
may not be that easy. Typically,
when I've done CDs that have
both ISO9660 and ODS-2 on
them, I've generated the image on
OpenVMS and burned the image
to CD using a PC.

Well, assuming you really mean DA15 (not DB15 :-)) then, yes, all you need
is a transceiver. The miniature type that fits straight onto the AUI
connector is best, and usually cheap and easy to find. After that, it's
just a question of having TCP/IP software.

At one point the RSX, TOPS and RT11 CDs
were all available as binary images. I know
I downloaded all of them and burned them to
CD with no problems. (Well, maybe a slight
issue with the RT11 one IIRC - I used W98
and whatever burning software I used
was not too happy verifying it ... seemed
usable though).
Tim does not seem to have any problems
with people downloading large amounts
of data so rather than ask for a CD, just
burn one.

You are probably thinking of "ex". But "ed" is a proper subset of "ex".
The classic answer to the question "point me to a guide" is
$ man ed
executed on any Unix or Unix-like system. If you don't have one of
those running, you can try, with your favorite web browser, a Google
search with the key words: unix man ed

Boot to non-timesharing then use ED (sorry no other choice usually)

boot to timeshare level and then log in as root with no password.

I worked for him and Mike Quinn back in the early/mid 70s, testing ICs in
the back room of Quinn's.
Any help would be appreciated.
Thanks,
Bobbe

FWIW, I think a central bug listing is a good idea.
Caveat on my opinion: I do not currently have any PDP-11s operational,
although I have several that could, conceivably, be put into working
condition on short order. I.e., I'm not currently running RT-11, although
it's on my List of Things to Do.

I found a TI data book dated 1971 and it doesn't even mention 12xx ICs. It appears that by 1971 TI had switched entirely to the 54/74xx series. I have a couple of even older TI books if I can find them.

Hi,
this weekend, we have been unsuccessful trying to get one of the ancient Unix
versions (V6 or V7) to run on a PDP-11/34. The plan is to have an ancient
PDP-11 on the VCFe in Munich running a proper version of Unix.
THe machine has two RK05 drives, RX01 floppy and a TS03 tape drive. Our first
problem is that we have been unable to find or make up a TS03 bootstrap.
We considered using RT-11 to transfer disk images to RK05 drives, but we could
not figure out how to get the image straight to the disk without having to
store it in an intermediate file and writing a RT-11 program to access the
disk sector-by-sector.
We have a lot of hardware at our disposal, so we took a Emulex TC12 Pertec
tape controller from a 11/44 (the 11/44 would also be nice as demonstration
CPU, but it has a SMD disk controller for which we have no drives). Not
having any documentation on the TC12 we just put it into the 11/34, but it did
not work (bus error LED lit).
So we're kind of stuck. Any ideas, hints or pointers (especially to a TC12
print set) would be greatly appreciated.
Thanks,
Hans

Sellam, why do you insist on labeling people with terms such as "silly" and
"lazy?"
Have you considering taking the easy way and suggesting that they might be
mistaken?
Also, do you still want this Amstrad 3" drive or shall I repost it to the
list? It's been several months . . .

FWIW, I've tried to contact Tim a couple times too, and not
gotten a response. I hope he's ok. :/

The point is, I can't see a real difference between a ROM chip
and a decoder + gates. Electronically they're much the same
thing. Physically, to change the program, I have to use a
soldering iron. It is _not_ clear to me why one is called firmware
and the other called hardware.
How about .. Hardware is the physical part(s) of a design that can be
seen, touched, crushed, thrown, weighed etc. Firmware is the idea
statically implemented in that hardware.

You get one that has the interface you need, but I think you
can swap interfaces; e.g. I've swapped a single-ended SCSI
interface board into one that I got with a differential SCSI
interface. Note that the interface board is screwed to the
back plate which has the cutout for the connector, so if
you get a different interface board you may also want to get
the appropriate back plate for it.

I haven't looked inside one with a Pertec interface, but the SCSI
interfaces expect to plug into a flat cable that is in the base of the
drive and I expect the Pertec interface would too.
There's also a four-slot card cage in the right side of the drive,
accessible by removing a top cover. The boards installed in this cage
make a difference too. Later drives have only three cards installed
(the read/write/PLL boards and formatter board were replaced by a
single board).
7980A and 7980XC are HP-IB-interface drives sold into the HP
minicomputer markets. The XC suffix means the drive was sold with a
variant board that supports data compression (meaning you can write
tapes that are only readable by other 7980XCs).
7980S is the same drive with a SCSI (single-ended I think) interface,
sold into the HP minicomputer market. At one point HP offered a
field upgrade kit to change your HP-IB drive to a SCSI drive.
There is also a variant board that supports 800 BPI (in addition to
1600 and 6250). I believe that 800 BPI and XC compression are
mutually exclusive (you can't have one drive that does both).
7979A is an HP-IB-interface flavor of the drive that supports neither
6250 BPI nor data compression. I'm not sure but this may simply be a
different-variant board as well.
88780 are drives sold outside the HP minicomputer markets, including
OEMs like IBM, Sun, and Tandem. Of course the OEMs came up with their
own model numbers.
I have some notes that say data compression was option 400 and 800 BPI
was option 800, but I'm not sure whether this applied to a 7980 or
88780.

I was thinking more along the lines of no fuse housing at all. Just wire
between some form of binding pin.

That depends on what he meant by "make ISO images of cd roms."
I read that to mean "I want to make a raw copy of the disk, and
I'm just saying ISO out of habit." You obviously read it to mean
"I want to make an ISO image out of some files I've got so that
I can burn it onto a CD."
So which was it?

No; assuming you've got files on a Linux filesystem, you use
mkisofs
to create the ISO9660 image file (with Rockbridge extensions).
Then you use
cdrecord
to burn the image onto the CD.
To capture an existing CD-ROM into an image file, most
likely, Chris is correct, but I haven't gone that direction
yet.

'Bout half an ANSI sh*tload which, of course, is smaller than the
Imperial sh*tload. It was, obviously, an ANSI sh*tload to which Slim
Pickins was referring in Blazing Saddles when he said "someone's

Hi all.
I need some advise.
In 3 weeks time Edward and I drive to Italy (some 1100 km)
to pick up several PDP-11/70 parts.
I have the oppertunity to drag 2 RM03 massbus drives and
some packs back home. Now I know already that these drives
weigh about 200 kilo, have a disk capacity of 67 Mb and
are really power-hungry: at 240 V/50 Hz. stand-by is 3.5 A.
running they consume 11.5 A. and rush-in current is 22 A.
My experience is that DEC tend to give high numbers for the
power consumption, but do these drives eat that much current?
Are they worth preserving? Or should I leave them where they are?
Next to the 11/70 is looks great (IMHO) but I would love to hear
some opinions from other collectors.
- Henk.
I see lots of references to these drives...
Do they possess multiple interfaces, or do you get
one that has the interface you need?
I've seen one with an HP-GPIB interface connector
on the back, and was wondering if I pull that rear
cover off, will I find a set of Pertect interface
connectors hiding there? Or is that simply a different
model?
Thanks,
-dq

It would be a lot more trouble to get the wire in and out. :) Otherwise
it's an interesting idea.
