Since we are talking about scratched glass, do you
have any ideas on how to remove scratches from the
face of a CRT?
I use Jewelers rouge I got from a Jeweler friend many
years ago. It works well on surface scratches such
as those you get from laying the monitor on the tube
face.

I will say that with a (pretty common) seagate 40M disk, you
can get a bare install of VMS 5.5 on there, and that's more
than enough to drive a tk50 and transfer files to other systems
over DECNet.
Could also netboot it from the other system.

Really? I don't believe I've ever seen one without the ethernet module.
That is to say, the cable that comes out of the ethernet ports on all
of the ones I've seen is always plugged into something. I know that the
ethernet was optional, and that the co-ax/aui ports were there whether
the board is there or not.

Were they sold apart from the systems? I wouldn't expect them to be
available in most cases apart from a system that was sold as a MicroVAX.
That said, DEC was supposedly very prolific with these systems, and you
ought to be able to get plenty of parts for them. The extreme
configurations (color graphics, 8/12[?]MB memory options, etc) are going
to be more difficult. The median seems to be b&w VAXStation, ethernet,
4M RAM option. That kind of thing ought to be pretty easy to find.
The "box" that the 2000s set on, which exposed the SCSI port, etc, is a
bit harder to find, but there are a few around. More common on the
"MicroVAX" variant, so if you have the choice, go for one of these.
(Unless, of course, the VAXStation would give you the color framebuffer,
or a large memory board)
Also, you have a better chance of finding a disk in the "MicroVAX" systems,
too. The VAXStations (more common too, I think) were lots of times run
diskless. It's interesting, because they put "load boards" in them for
that. Basically these are resistor packs that load the PSU up so that it
won't panic due to the lack of disks. They're nice to have for -- for
instance -- running a system with no disk, or use with Wolfgang Moeller's
SCSI drivers for these systems. (Which I've not tried yet, but will
eventually, supposedly, you can put SCSI disks in them that way. It's
_very_ unsupported, of course :)

Honestly, any 2000 you find will probably be reasonably cheap (like in the
$20 range, max) At best, you'll find one in a scrap pile somewhere.
They're solid systems, so even if it's gotten left in a warehouse for ages,
I wouldn't expect much trouble with it.

I'm not sure what Doc is talking about with Cerium oxide.
It cleans up well and is a little off white in color ( sometimes
a little yellowish ). Rouge is really messy and will stain everything.
I've not worked wit chromium oxide so I can't say it is
better or worse that cerium oxide but I don't know how it
could be a powder and be any better.

Hi everyone!
I'm not sure if this list is even active anymore, but let's hope that
this message will get routed to its proper destination.
Essentially, I'm cleaning out part of my basement, and I have a ton
of stuff that I really don't want anymore. I am offering it free of
charge to anyone willing to come out to Kalamazoo, Michgan and pick
it up. Here's what I've got:
* IBM PS/2 Model 50Z, partially stripped.
* NCR System 3300, no HDD (scsi), floppy, or MCA cards.
* DEC VT420, some scratches on screen but works AFAIK.
* Apple Power Mac 7200/90 and 7200/120, stripped, although
if someone wants them, I'll put them more or less back together
sans RAM and HDD (scsi).
* IBM ThinkPad 750 laptop, for parts.
* Compaq Contura 420CX laptop, for parts.
* Toshiba T3100 (gas plasma screen) laptop, for parts.
* Roughly three large cardboard boxes full of boards, including
some of the following items.
1. 8088, 8086, 80286, 80386, and 80486 motherboards and CPUs
2. LOTS of ISA cards, including video, I/O, hard disk controllers
(even some hardcards), LocalTalk cards, networking, etc.
3. Some VLB cards, mostly video, although some I/O and hard
disk controllers are also around, I believe.
* Data General dual 5.25" floppy drive, rack mount. I don't know
if it works or not, but it seems to be in good condition.
* USRobotics TotalControl rackmount chassis with network management
card, around 15-20 modem cards, dual power suppies, and some other
stuff. I've got a bunch of cables for it, too. I'm currently using
it as a table, but if someone wants it, I'd be glad to get rid of
it. :)
* Token ring hardware -- lots of nice 3Com/Madge/Proteon cards and
some MAU/CAU units.
* Some other stuff, maybe -- PS/2 Model 5x and 70 systems, Commodore
64 equipment, etc.
In general, I've got a TON of stuff sitting around here that I'd really
like to get rid of. If there's no interest, most of it's going to go in
the trash in a couple of weeks here. If you might be interested in paying
me a visit (or having a proxy do so), please contact me and we can get
something worked out -- I hate throwing stuff away, but I really want the
space!
Thanks!
Sean
BTW -- I've also got a fully loaded, functional PDP-11/34a system in my
basement and a broken RX02 dual 8" floppy drive laying around. I'm not
really looking to get rid of it PER SE, but I do realize that I will
probably never do much with it. Therefore, if anyone might be interested
in making trades of interesting equipment (e.g. larger SGI systems, LISP
machines, strange Xerox computers, etc), please contact me as well, and
perhaps we can get something worked out!

Hi,
in my VAX 11/780 I have the PDP-11/03 alias KC780. And it has
the following memory board right now:
M7944 MSV11-B Q 4-Kword 16-bit MOS RAM (external refresh)
But, since I'm planning to upgrade to an 11/785 I need additional
RAM. When it showed up on ePay I buyed a
M8044-DA MSV11-DD Q 32-Kword 16-bit MOS RAM
but the boot program will not load with this. Why would that be?
From the error I got it appeared as if may be there is just some
jumpering to do, but I have no clue as to where and what.
Looking at the UNIBUS/Q bus field guide beginning from M7944
and then scanning forward to the next MSV11 I find:
M7955-AD MSV11-CD Q 16-Kword 16-bit MOS RAM with on-board refresh
and then the family of M8044s
M8044-AA MSV11-DA Q 4-Kword 16-bit MOS RAM
M8044-AA (Also M8044-AB, -AC, -AD)
M8044-AA Refs: EK-MSVI1-OP, MP-00566
M8044-BA MSV11-DB Q 8-Kword 16-bit MOS RAM
M8044-BA (Also M8044-BB, -BC, -BD)
M8044-BA Refs: EK-MSVI1-OP, MP-00566
M8044-CA MSV11-DC Q 16-Kword 16-bit MOS RAM

M8044-DA Refs: EK-MSVI1-OP, MP-00566
Does that mean that I should have the M7955-AD RAM instead?
This is confusing. And I'm not even asking for Q22 bus or PMI
memory stuff. What's the thing I'm missing?
thanks,

Hi Ken
I wrote one once in Forth for a 2901 project. It was relatively
trivial ( at least in Forth since the essense of Forth is
to change Forth into the application and not to write the
application in Forth ). It would be difficult to have a
good general purpose meta-assembler since the variety of
ways to wire up a bitslice are so great that a "one size
fits all" would be difficult.
In my case, I just coded up the bit fields of my controller
( some of the bits ran outside hardware ) with meaningful
names. It put things into a binary image file that I
first blew EPROMs with and later, after debug, faster ROMs.
I was years ago but these really are not that hard to write.

Hi
I think from what Dan says, it isn't a STDBus. I think
STDBus is 50 pin. This board has a 44 pin connector.
This is similar to what was used on the COSMAC stuff.
Maybe it is compatable with that??
( also used on the KIM/SIM stuff ). Of course, it
may just be some propietary bus.

The main reason I scan at 600 dpi and not save space
by dropping to 300 dpi is that the current crop of OCR
software seems (in my limited experience) to produce
better results with 600 dpi. (I cannot go higher than
600 anyway, but I probably would not bother with 1200dpi
because the OCR stuff I have won't even accept it).
I'd rather scan the manuals once and wait 10 years
for OCR to get to the stage that it can handle the docs
with maybe one error per 100/pages (rather than
the current standard of multiple errors per page ...).
I don't really want to be going back and doing it again!
The long term goal is definitely OCR. Although by the
time it's good enough we may well all have OC48 feeds
to the home and C3D recordable 125GB drives so there
may be no need :-)

Is that when a page is first displayed (i.e. for each
change of page) or just the first page? I assume that
you download and then view locally (I have issues
with both NS & IE when trying to use then to view
local PDFs via HTML ... I assume it would be
even worse with a download thrown in for
good measure!)
>BTW thanks for doing all the work!
No problem. I'm was backing up my manuals
just in case and then saw others making theirs
available and followed suite. I just forgot to
stop when I ran out of my own manuals ...

An interesting PDF. They get strange changes of font
on pages 2 & 3 - I wonder if the original has that or
whether it's just an artifact of the OCR. A mixture of
text and background image (which is also text).
I wonder if they might be interested in converting the
multiple hundreds of manuals that live on the current
crop of DEC document web sites ...

The stuff I've scanned (like m3100ma1.pdf
mentioned above) is usually US Letter size
and done at 600 dpi bi-tonal (1 bit per pixel).
The scanner happens to LZW encode the
TIFF file. There is no option to G4 encode.
That usually turns out to be 200-400KB/page
but it so happens that one page in that
manual did not look too good. So I redid
that one page as greyscale (8 bits
per pixel) and that just so happens to
be over 50% of the total file size (i.e.
wipe that one page and you are looking
at more like 400KB/page). It's only 14 pages
or so, hence one greyscale page makes
a big difference.
I've seen someone else quote figures of
50-70KB/page for G4 encoded 300 dpi scans
of TOPS manuals, which I assume are the
typical US Letter size. Obviously going to
600dpi might be expected to produce a
factor of 4 increase (i.e. 200-300KB).
Or it might not - who can say with compression!
I don't see a SC41MS.pdf on that page so
I have no idea of the scanning resolution
or the encoding.
>Can one re-convert PDP^HF files?
I've found that using Acrobat 5 in the office
I can covert PDF to individual G4 TIFFs
(although this is *slow* but it is unattended)
and I can then re-import these (in groups
of 50 max) which is reasonably quick.
But it sucks away time. So if anyone else
needs them cut down, be my guest :-)
For the few that I've had to process manually
(i.e. book format, with pages individually
scanned as all-odd-ones, all-even-ones)
the conversion to G4 TIFF is a part of
the process I use to stitch everything
back together in reasonable time. In that
case I'm seeing a reduction of maybe 25%
in size (although I've not tried to measure
it on a reasonable sample ... so don't
quote me).
If the scanner gets an upgrade that allows
it to do G4 TIFF, I'll certainly use it. If a
tool turns up that can do unattended conversion
of TIFF-in-PDF -> G4 TIFF (or better yet,
G4-TIFF-in-PDF) I'll certainly use it.
Antonio
Hi Dan
I'm not sure but it looks like it may be
a "Standard Bus" type board. I don't recall the
pin combinations but it looks like the same
form factor.
There are a lot of different Standard Bus manufactures
and you should be able to get cards and back planes
easily. Count the pins and look the spec up on the
web and see if it looks the same.

Forget what? That will prevent an auto-boot, but won't keep the
system from operating. It's not serious; just serious enough that
they wanted to wait for some console input before going ahead. Go
ahead and try booting it.

If you're getting the prompt, the counting in hex, and the
CPU ID (something like KAXXX-XX, I think), you're doing
fine in the cable department. I suppose if not, maybe the
VAX prints its errors to all the ports on bootup. In that
case, it won't take input from that port, and you'll need
to get the right cable to tell it to boot. You still don't
absolutely have to get the network connected, though.

The subject of my query isn't 10 years old yet, but
since it's DEC equipment and there are many DEC fans
here, I'd like to post it anyway.
About six months ago, a list member offered me one of
these Alpha ATX-factor motherboards for a very reasonable
price. As often happens with many of us, the deal has not
gone through.
If anyone else still subscribing has a cache of these
and is willing to part with one I'd appreciate it. I'd
prefer a trade for a Calcomp Digi-Board III digitizer
tablet with 16-button puck, but I could also trade a
Mac Quadra 700 or Quadra 650 (as I have a couple extra).
I also might have other trade-worthy items; just write
me and we can discuss it.

That's obviously several hundred more pages than
you might care to read, but if noone has a canned
config for you, this might be what you have to do.

It's a simple straight-through serial cable with pins 8 and 9
tied together on the machine end. Nothing fancy. You can make
one up in five minutes with parts from radio shark.

Rather than pdf, consider using DjVu; it's a LOT more compact (I recompressed some pages from the RT-11 Software support manual that I'd scanned a while ago with DjVu, and went from about 900 Kb/page to 30-40 Kb/page). Needless to say, I was very impressed.
The DjVu viewer plugin for various browsers if free, and a program which scans images to individual files is also free from http://www.djvu.com/. I first heard about DjVu on this list, and it is one of the neatest pieces of compression software that I've seen.

I'm at home now and I've been able to check
some manuals, without too much luck though.
The "LSI-11, PDP-11/03 user's manual" discusses
the KD11-F (M7264) and KD11-J (M7264-YA)
which seems to be the same module with
no RAM and packaged differently.
I don't know whether that's the module used in
the 11/780 console. I'm sure it's in one of those
manuals, but I bet you can find out quicker
by looking :-)
It also discusses usage (and jumpering) of
the MSV11-B (M7944) 4K memory board.
If your LSI CPU is the M7264(-YA) then you
probably want this manual anyway.
I also have a copy of the MSV11-P User
Guide but that discusses the M8067-LA,
-KA, -FA which are 256K, 128K
and 64K boards. Maybe useful as a
general reference but probably not applicable
to jumpering your stuff.
My random guess is either you have the
refresh wrong or the memory board
starting address is wrong. Sadly, even if
the guess is right, neither of these manuals
are likely to help you sort it out. Let me know
if you want them ftp'd somewhere anyway.

Define extra. :) You know they have 2M on board,
right? Do you have one without any add-in memory
option?
I've honestly never seen one like that. Again, I
have plenty of "spare" VAXStation 2000 stuff, but
I'd like to stay away from committing to ship
anything just now.
The only memory options I have are 2 and 4M boards,
which would give you a total of either 4 or 6M.
You do know that you can only fit one RAM board in a
system, right?

I scanned all those 11/780 docs and sent them along
to DFWCUG but the real praise should go to
Alain Nierveze who sent copies of the manuals
to me in the post for scanning.

These are certainly "old-style" DEC technical manuals.
They virtually describe the machine down to the
individual chips.
All we need now is a full set of prints
for the VAX-11/780 ... or a full set of
tech manuals for the VAX-11/750 (or
VAX-11/730) and someone can then do a
full implementation in an FPGA :-)
