Quoting from the manual:
* To copy high capacity, non-copy-protected disks (1.2 or 1.44 MB)
you must use the TCM program included on the Deluxe Option Board
software disk.
* The Deluxe Option Board is not capable of copying copy-protected,
high density disks. As these disks become more prevalent in the
market, we may include this capability.

I'm thinking what this means is that you can use TCM to copy 1.44MB
3.5" media, but there's no guarantee that it will reliably copy
media that are copy-protected.

Recently I picked up a Wang Professional Computer. Can't find a model
number on it anywhere. It 8086 based, 256KB RAM, 360KB FDD, 10MB HDD.
It runs MS-DOS 2.11, but it is not PC compatible.
A long time before I got this machine I found some software for it. A box
of original disks all marked "Wang Professional Computer". It includes 2
versions of the integrated word processor, MS Chart, DOS3.2 and Windows
1.03. Both versions of the word processor run, ms chart bombs saying I
have the wrong graphics card. Neither DOS 3.2 nor Windows 1.03 will
install. DOS 3.2 just hangs the machine, Windows 1.03 bombs with an
interrupt error. The disks seem to read okay.
Anyone know what I'm doing wrong or have working copies?
I vaugely remember seeing pictures of this machine in the Windows launch
issue of Byte. Though it would be cool to have windows running on something
other than a PC clone. I think I've even got a copy Balance of Power for
Win 1.x around here somewhere.

No need to reboot after starting File Sharing, and in fact, rebooting can
cause the file sharing to be turned back off. So first step, go back into
the Sharing Setup control panel, and make sure the Start button says
"Stop" (if it says "Start" then click it again, and wait for file sharing
to startup, the button will change to Stop when it is up and running)

In the remote computer's Chooser, under AppleShare.
If you don't see the server there, make sure both computers' AppleTalk
control panel is set to use the Printer Port, and that AppleTalk is
turned on (and make sure the serial TeleNet connectors are plugged into
the Printer port and not the Modem port).
Also, on the TeleNet connectors, make sure there is a terminator in the
unused phone jack on each. I don't remember if the ones I gave you have
termination switches on the side, if they do, just make sure it is set to
ON (if it is, then you don't need a terminator in the 2nd jack... I know
either they have they switches or I gave you terminators... I don't think
I would have been brain dead enough to give you them without a way to
terminate them)

Well... audio tapes don't work as a substitute for a D/CAS cassette. At
least not with my TEAC drive.
First attempt, drive takes the tape, but starts blinking the access light
as soon as the drive is locked, never tries to do anything with it,
software says "No Media".
After a quick 2nd look at the transport, I see a small finger sensor
looking for that notch. 30 seconds later with my pocket knife, my audio
tape has the notch.
2nd attempt, drive sees the tape, software reports "Busy" as the drive
spins the tape to the end, clacks to the end and tries to spin some more,
then gives up, rewinds a bit and stops. Software reports "Hardware Error".
My guess is, it is looking for some kind of end of tape marker. I tried
both clear leader and leaderless tape, neither worked. I also tried a
higher grade tape (Type II, 630 oersteds or whatever that word is). I
don't know if the end of tape is a specific magnetic marker like a
format, or what. Winding the tape to the end in a tape deck and putting
back in the drive causes it to rewind the whole tape until it clacks at
the end again. So it is definitly trying to rewind to the start of the
tape and is simply never seeing that it is at the end.
It is possible that the drive is broken, but since it is seen by
Retrospect on the Mac, and gives status updates as it goes, and the
transport does its thing... I tend to think the drive is fine and I just
can't use an audio tape.
So... does anyone know a supplier of these tapes? I haven't been able to
turn up anyone that actually sells them anymore. A few people on this
list offered to try to locate a spare tape for me for testing... but I'm
not going to ask anyone to go thru that effort if I can't get a regular
supply of tapes anyway.
The drive is a TEAC MT-2ST/N50. The following appear to be compatible
tapes: MaynStream 20; Teac CT500 D/CAS; Verbatim ST500; Teac CT-600H;
Verbatim ST600; Maxell CS-600HD; MaynStream 60; Teac CT-600N; Maxell
CS-600XD; Verbatim ST600XD; MaynStream 150.
All in all, it probably isn't worth much more effort. Its only a 150 MB
drive anyway. So for normal use, there isn't much I can do with it (at
least not when I deal with the cost ratio of Zip disks or CD-R's).

Beginning in a few days, and proceeding over the next few months as needed
a 'catalog' page will be created on the 'Computer Garage' site. For each
item there will be a description, a thumbnail picture when practical, an
estimated shipping weight, and a date.
I have the 3.1 or 3.2 system, scriptsit, dev system, mbasic, and filePro or
Profile16. How urgent are your needs? I only have them available on 5.25"
disks (follow the directions on Frank Durda's site to connect up a 5.25"

Subject: XENIX Distribution Disks
Well, I found someone with a Tandy 6000 keyboard to sell and it should be on
it's way to me tomorrow. Unfortunately, when it gets here, I will have
nothing to use it for, as I accidentally wiped XENIX completely off my
6000's internal hard disk while trying to format a secondary *external* hard
disk. I will never again assume that a program named 'hdinit' will actually
ask me *which* disk to erase, nor that it will ask for *ANY* kind of
confirmation before wiping the internal hard disk...
So I am now in the market for some Tandy XENIX distribution disks for
version 3.whatever. I don't know the exact version number of the OS that was
for the 6000 specifically. Also, should anyone have the Multiuser BASIC
disks, or Profile for XENIX disks, those were lost as well... I didn't have
any of the original disks for anything dealing with the 6000.
I'd also like to get my hands on something my system never had, whose
absence was very noticeable - the XENIX Development System, which contains
things like the C compiler, mail, and many other things I don't consider
optional in a UNIX-based system.
Any help is greatly appreciated...

Hi
We make a 64 bit/32 bit x86 machine.

Submitted for your amusement, something picked up today while out
scrounging (really looking for non-classic bits). It's a luggable.
Poking out the front:
5" CRT
two half-height 5.25" floppy drives
(inserted floppies have extra write protect notches cut
for use as flippies)
40/80 switch
modular jack (6-conductor)
brightness and horizontal hold knobs
Poking out the back:
GAME (DE9P)
RS-232C (DB25S)
PRINTER ("Centronics" connector)
VIDEO (RCA socket)
label, handwritten s/n 1193 and checkmarks for 110V 60Hz
The detached keyboard has a modular jack too. It's also bit-paired
(shift-2 is '"'), in fact it mostly follows the Apple ][ layout (and
has <- and -> keys), and it has what look like BASIC keywords on the
fronts of many of the keys, including HTAB, VTAB, GR, HGR, and TEXT.
No cable between keyboard and luggable.
I'm thinking it's an Apple ][ clone of some sort.
It doesn't quite power up: no video display on the internal monitor.
Pulling the top cover shows the guts. The top floppy drive is a Teac
FD55A. The motherboard has five slots that look like Apple ][ slots;
the silkscreen on the motherboard labels them S0 S3 S4 S5 S7. Date
codes on the visible ICs are 81xx and 84xx so I'm guessing 1984 at the
earliest.
Someone's been in here before. The 40/80 switch has a lead to a paper
clip that ties it (mechanically at least) to an insulated red lead
that goes from the motherboard to the display board; this red lead
would appear to be the +ve supply for the display. There's also a
loose metal cover over the display section; it looks like it may have
been held together or insulated by tape or sticky cardboard at some
time but this has been removed somewhat.
Powering up with the top off makes a red LED on the motherboard light
up solid, but the CRT filament doesn't glow.
Anyone ever seen one of these before?

Hi.
I got some more parts of that disassembled PDP-11/34A yesterday. I think
I have now all PSU parts:
- power inlet unit with mains cable, circuit breaker ... and a PCB that
looks like a small PSU.
- one big transformer
- one small transformer
- one H785 battery backup regulator module
- one H745 -15 PSU module
- two H7441 +5V PSU modules
- a PCB that is labled "BATTERY CHARGER"
- a bag full of screws
Some time ago I got the front half of the BA11-K, i.e. a card cage with
the system units, all UniBus cards, power distribution panel and front
panel.
Obviously missing:
- back of the BA11-K where the PSU bricks, transformers, ... are mounted
- fans
- bulkheads for the console serial line, the serial multiplexer, RK07,
...
- UniBus extender and terminator. [1]
I got the card cage, power distribution panel, system units and all
UniBus cards in one piece, but disassembled it to clean it. I know how
to remount that, but I have no clue how all the PSU parts fit togeter
and if there are some parts missing I didn't list above. It would be
nice if someone who knows this machine could give me some hints...
I was toled that one of the PSU bricks is broken. I found some manuals
on http://www.mainecoon.com/classiccmp/PDP-11-34A/ but I can't read
those TIFFs. I tried with xv, gimp, tiff2ps, Netscape 4.7x, Mozilla 1.2.
I took the CDR with the TIFFs with me to work and tried to view them on
a WinXP machine (puke). The machine nearly crashed when I tried to open
the files. My SGI Indogo2 is broken so I can not try some IRIX tools.
Where else can I get some schematics of the PSU bricks in a readable
form?
[1] There is an other, smaler BA11 with a custom UniBus interface from
Linotype for some photo typesetting machinery... I have the M9312
bootstrap terminator for the "beginning" of the bus where the CPU
resides.

I'm finding many aspects of this discussion very compelling. It got me to wonder some things.
How would you categorize and describe classic computer items? Is there an accepted descriptive benchmark in the collectors discipline?
Or better still, how would you *like* to see it done? What would be an appropriate descriptive level of a flip chip, a unibus terminator, a cable, a power cable, a backplane, a cabinet part? If you had a museum or archival collection of these DEC things, what would you want to know about them that would make them useful to you?

Argh!! I knew I disliked most museums for a good reason :-)... This is
simply rediculous. A PDP9 is a PDP9 no matter what cabinet it's installed
in, of even if it's jsut loose backplanes and PSUs...
Mind you, I once saw a list of valves (vacuum tubes) that one museum was
offering to another. The list had a column of 'condition'. No, it didn't
give the emission and gm figures. It didn't even say if the heater was
continous, and the getter silver (not white, which would indicate air had
leaked into the valve). No, it described how clean the glass was...

The obvious extension of this is that art galleries should throw out all
but 10 of their paintains on the ground that they 'already have 10 pieces
of canvas with paint on them' :-)... And that libraries only need to keep
10 books ('we already have 10 sets of bound pieces of paper with ink on
them').
Somebody is going to have to educate museum curators about the importance
and meaning of technical and computer artefacts...

Hi,
I recently picked up a model 4 ver 1 with a problem. The system originally
worked and booted, after moving the system it started to display random
characters
on power up and failed to boot.. I removed socketed ICs and cleaned
the connectors.
The system now displays a blank screen on power up ( although the drives
spin, and
it could be booting ). If I disconnect the FD controller from the main
board, the
system jumps into basic ( with video ) and seems to operate. Print
fre(0) returns
somthing over 48K with the fd disconnected. Any hints?

OK. I've got an ftp server lined up, can even put them on CD's and duplicate
a batch on scrap discs (don't ask, I was trying to calibrate a termal CD
printer). The big question:
What is the best tool to create the disk images? Rawread/rawwrite? dd? cpio?
something else? The easiest thing for me is either dd under linux or raw
read under MSDOS (like the linux boot discs). I have lots of 5.25" disc
drives laying around. All I have to do is hook one up.
I'd rather not create the 8" discs myself. The media on them seems to peel
off onto the head if you have cheap ones. Then I have to take the drive
apart, clean the head... since I've already copied most down to 5.25 (I
still have to do mbasic, multiplan, and Profile 16+), I will make images
>from the 5.25" discs as time permits and put them up on a public ftp server
for a while.

No, that's backwards. In the case of DEC RX01 or RX02 with a DEC
controller, the controller card (in the QBus or Unibus) is fairly dumb,
it's just an interface. The "smart" stuff is in the drive enclosure.
The controller passes a FORMAT command to the drive, the drive
chunters away and executs it, and reports back to the controller when
it's done.
In the case of third-party controllers with "industry standard" drives,
the controller is "smart" and the drive is dumb. The controller does
the formatting, and sends control signals and a data/clock bitstream to
the drive, so you can't do anything
> The same situation occurred with the DEC RX50 floppy media.
> The DEC RX50 drive could NOT perform an LLF.
It works differently than an RX01/RX02. In fact it works exactly like
the third-party RX01/RX02 case above, except that DEC saw fit not to
include formatting routines in the RQDX1/RQDX2 controller. The RX50
drive is an oddly-engineered variant of an industry-standard 5.25" dual
floppy, with almost exactly the same control/data signals.

Yes, the RQDX3 includes firmware that can do the formatting. However
the layout it creates is fixed, and not useful for an RX50 (which has
almost exactly the same hardware interface as an RX33).

Correct. The answer is "no", for exactly the reason Jochen describes,
and indeed John's webpage says so.

Hi Jim
There is a chance that the first crash also damaged
the system info on your boot disk. Have you tried using
another disk?
You could also try putting the disk controller in but
put tape over the select line( not sure what is involved
here without a schematic ) and tie this line ( lines? )
so that the drive doesn't access. The idea is to see
if something in the controller is loading the bus. If
this is the case, BASIC won't boot. You could then isolate
a pin at a time until you found the failure. Small pieces
of tape work well for isolating edge connectors.
That is about as far as I'm willing to make any guesses.

What does it mean when the light on a thinline floppy in a Tandy 6000
repeatedly blinks to the pattern:
<long blink>...<blink><blink><blink>
When I put a disk in, the drive makes healthy noises, but the light just
keeps blinking like stated above, and the system seems unable to detect that
there's a disk in the drive.

As far as I know, the only possible way Tony could have obtained
my e-mail address was through cctalk(a)classiccmp.org since I first
started to use it only a week ago. OR someone who is aware of
my PDP-11 addiction gave it to him? In either case, I don't have an
objection. But if there has been any hacking, then I would like
to know about that aspect!
In any case, if I am receiving spam via cctalk(a)classiccmp.org,
then others need to be warned! If not, then I want to reply.
Sincerely yours,

Hi
As was mentioned, not all controllers do single density. MFM double
density is no problem. There are a number of programs out there
that handle differing sector counts and sector sizes. You could
also write your own. You'd need to know how to setup the DMA and
the floppy registers. It isn't real hard but it is easiest if
you have some examples.

>Also I wonder if it will work with intel development system disks.
If your disk are single density and you have a controller that
handles single density then you are OK. Intel's double density
was M2FM and not MFM, for the 8 inch disk. About the only way
to read this was with an Intel M2FM controller. As far as
I know, these only existed on multibus boards.

I have listed some more stuff for auction over at
http://www.sellyouritem.com. I have found quite a few DEC flip-chip and
other boards that are being listed there in addition to other stuff of
interest to listserver members. The area of main interest for list
members is in the Classic Computer section at:
http://www.sellyouritem.com/ListAuctions.html?CategoryID=1497
The things I am listing there are for 3 day auctions, and that should
give everyone here a chance at them before they head over to (explatives
deleted) Ebay. If you think the pricing is wrong, let me know as this
was my best guess at reasonable pricing for list members. Again, the
main idea behind putting them on SYI is to allow listmembers an equal
chance at anything they might be interested in. I'm trying to list about
10 items/day there.
Stuff that I will also be listing include a PDP-3L, Microvax, some DEC
Disk Drive
cartridges R????, and some other DEC cards that I have not identified
yet. I *think* there are also several 11/34 cards that I have not listed
yet, hopefully later today.

Exactly what I did with my 8-year-old niece at Christmas. She's really
into "sums" and arithmetic at the moment, so when I wanted to play with
my 8/E, I taught her a little about binary, showed her how to read
octal off the switches and lights, and we added some numbers. She
loved it.

How do you do this? I am interested.
What floppy controller do you use? I am assuming it is for the ISA bus?
Anything for a PCI bus.
Anything for EISA, I am keeping one EISA bus system.

Thanks for the tip on the D Bit FDADAP. I will probably get one as I think it
meets my criteria. I am not particular interested in reading DEC RX01 & 02s.
Those I will pass onto the list as I find them.
My main interest is in CPM systems and disks of which I have several.
Also I wonder if it will work with intel development system disks.
Thanks again for the leads. I will look at the CPM FAQ too.

Hi, folks. I'm starting a vacation this Saturday with a few days in
Manhattan. Are there good classic computing or telecommunications
museums, or other interesting sites, there? I know IBM used to have a
museum in Manhattan, but I never got to see it -- I'd hate to miss
something else just before it closed.
Any help is appreciated, and I'll gladly take pictures and/or send
postcards for those who are interested :-)

I really could use a bit of help. I have been trying to reach Martijn Kruger
of Retro Computing Unlimited. I was corresponding with him and then haven't
heard from him. Not sure if I said something wrong but he was helping me find
some technical manuals. If anyone can reach him or knows how I should contact
him, please let me know.
Thanks

Dear All,
We have received a lot of old DecServer 700 but we are looking for the
WWENG2.SYS image ;-)
We have looked around the old digital ftp server, but there is only
the pr0801eng.sys (not really useful).
Where can we get the WWENG2.SYS image for the DecServer ? What is the
software licensing for this image ? Is it linked to hardware or was it
a separate product from Digital ?
Thanks a lot.

Hi,
I recently picked up a PDP11/34 for restoration from a surplus dealer and
spotted at the same time an Interdata Model 74 gathering dust. Needless to
say, I managed to get this as part of the deal..
I'd like to try to restore this back to working condition, but my various
searches for information on early Interdata models seems to have born little
fruit.
Does anyone have any information, documentation, engineering diagrams for
this machine?
Thanks,
Toby
I ran across your 11/4/02 post about leaking capacitors. We have two
(so far) PCs afflicted. What scares the crap out of me is that we have
a number of them at customers as voicemail servers. You said you
replaced with AV22 and AV18, and we'd like to find out if that'll work
for us. I also read at overclockers how to replace capacitors. I
believe both the PCs are 700 mhz Celeron running Windows XP.
I'd appreciate any advice you can give us.

Well, I found someone with a Tandy 6000 keyboard to sell and it should be on
it's way to me tomorrow. Unfortunately, when it gets here, I will have
nothing to use it for, as I accidentally wiped XENIX completely off my
6000's internal hard disk while trying to format a secondary *external* hard
disk. I will never again assume that a program named 'hdinit' will actually
ask me *which* disk to erase, nor that it will ask for *ANY* kind of
confirmation before wiping the internal hard disk...
So I am now in the market for some Tandy XENIX distribution disks for
version 3.whatever. I don't know the exact version number of the OS that was
for the 6000 specifically. Also, should anyone have the Multiuser BASIC
disks, or Profile for XENIX disks, those were lost as well... I didn't have
any of the original disks for anything dealing with the 6000.
I'd also like to get my hands on something my system never had, whose
absence was very noticeable - the XENIX Development System, which contains
things like the C compiler, mail, and many other things I don't consider
optional in a UNIX-based system.
Any help is greatly appreciated...

Ok you funny talking folks on the upside-down island, you have a job to
do:
Chips are down for computer museum

The Australian Computer Museum Society is about to lose its space and
needs 1,000 square meters to move its collection into. They have to find
something within 6 weeks because they say it'll take six months to move
their collection, and they must be out bu January 1, 2004.

When selling stuff on ebay, you have the option of setting your start
date/time to something other than right now. It costs more to do this,
but it is an option.
So like Jeffrey's post said, the auction starts at 6pm PDT Wednesday. So
I would assume the link will become valid as of that time (it would be
nice if ebay gave you a slightly better message than just Invalid Item so
you know you are looking at a not yet valid item as opposed to a totally
incorrect listing ID)

I've just listed some M series modules and a Quad Extender Board over at
Sellyouritem.com. The URL for the classic computer stuff is at:
http://www.sellyouritem.com/ListAuctions.html?CategoryID=1497
These are set for a three day auction to give listmembers a chance at
them. I plan on listing about a dozen+ items a day, so it might be
worthwhile to check over there occassionally.
We've had some discussion about First Come/First Serve, and that
basically means whoever lives at their computer has the best shot at
anything offered to the list. I think this might be a fairer way of
doing things without giving the whole world a chance at stuff. SYI has
*NO* listing fees, and FVFs are slightly less than on Ebay. My feeling
is that a three day auction gives everyone on the list a chance to look
at the stuff, and bid if they are interested.

As promised, the bulk of my collection will be up for bidding in less
than 24 hours.
For an interesting twist, I have decided to sell my collection in one
large lot instead of several medium-sized lots. This will hopefully
maximize both convenience and entertainment. Remember, I'm also
accepting items in lieu of cash.
The auction kicks off today (Wednesday) at 6PM PDT (1AM GMT). I wish all
contestants a safe, enjoyable bidding experience.

Any value to an IBM 8560? Or more correctly, is it something that someone
on the list might be interested in.
Its a full height tower 286 IBM ps/2 machine. There is at least one hard
drive in it, and I think I have a 2nd for it (not sure the sizes, 20 or
40 MB I think). Last I knew it booted and worked fine.
I've had it kicking around for some time, and its taking up space. I
think it weighs about 40 lbs, so figure on 50 lbs packed for an estimate,
shipped from 07450... anyone want it?

Hi there
I saw your post as a result of my search criteria in google, i am chasing
any and all documentation on DEC LA 120 and any other relevant PDP material.
I have just secured a position with a company that supports this type of
hardware, and am having difficulty wrapping my mind around the sheer
immensity of the equipment.
So any help would be very much appreciated, as i search and search for any
documentation.
:)
Best regards
