I would like to acknowledge the passing of Prof. Pat Hume. He was a
pioneering programmer in Canada working on TRANSCODE(before most
programming languages came along) and published/co-authored several
early books on programming for high school and university students. He
was also a popular host of the CBCs "The Nature of Things" a
pioneering TV science program.
Happy programming/computing.
Murray--
I am using Mac OS 9 to run the MPW IIGS environment to assemble some old
source code. I have problems when it comes to Pascal code. I see in other
source that it specifically requires TML Pascal. The version I think I need
is TML Pascal for MPW IIGS 1.0. This is not TML for the Mac or Apple IIGS.
Googling reveals others have searched for it which resulted in dead-ends.
This software may be extinct but I thought I'd ask if anyone has a copy?

This whole thing started when Tony asked why you REd whatever machine it
was, when he had already done so, and there is a lot of other equipment
that needs reverse engineering. That set you off on a rant about
mistakes Tony had made, how many machines you had REd etc etc. If you
had just counted to 10 before replying, and instead asked Tony what he
meant, the whole thing could have been kept to a civil level. Instead it
all degenerated into some kind of pissing contest. You did actually come
across as feeling threatened, not as being reasonable. You made yourself
the aggrieved party by your knee-jerk reaction.
Unless Tony writes one thing and means something completely different,
if you read his responses, it does rather look as if you have
misunderstood him and gone off the deep end. I'm sorry, but you started
this fight yourself.

I'm looking to equip my unibus pdp11/34a and qbus 11/83 with Ethernet cards. I have no experience with old DEC network hardware, and I need advice.
On the qbus side, what is the difference between a DELNA and DEQNA? Is one superior? Is there a better alternative?
As for unibus, any advice at all would be great. If it matters, my 11/34a has both cache and floating point, 128kw memory, but I don't know if there are any operating systems with tcp/ip that will run on it.
Thanks for any thoughts.
The original Apple II case could be easily open by students and was not
suitable for school use. (It may not have had the proper UL approval.) The
dark Bell & Howell Apple II case was locked down and somewhat student proof.
Bell & Howell also knew how to sell projectors and other audio visual
equipment to schools everywhere. This is how Apple fortuitously stumbled
into the education market.

Some of us have personalities which are special in one way or another,
which is to be expected in a hobby like this one. I think it is
important to allow other people the benefit of the doubt. If someone
says something that one at first takes personally, one can always ask
politely what they meant, as it is quite likely that one has
misunderstood what the other person meant.
Tony in particular, apart from his British humour, I believe is very
uncompromising about doing what he thinks is right, for which I think he
deserves respect, and even if one disagrees with his idea of what is
right, one has to accept that that is the way he is, just as we expect
to be accepted the way we are.

I'm planning on constructing a PDP-11 S-100 card and intend to use the F-11
chipset. However, I've yet to find any decent information on the F-11, or
the J-11 for that matter. Does anyone have the pinout information, or any
other good design info?
Having the MMU pinout might be helpful as well.
I know there has been interest in this before and would love to help create
a final product. A PDP-8 S-100 board using a 6100/6102 or 6120 would also
be nice. What to do with the extra nibble in RAM, though? Checksum?
Thanks,

Hello list,
the recent post of Lyle regarding Emulex tape couplers reminded me that I've been having an Emulex converter subsystem named "SMDI" for years now, but was never able to use it.
The reason: This subsystem is housed in an extra 19" enclosure and unfortunately, I obtained this box without any SMDI converter boards.
The idea of that box is neat: SMD-discs can be attached to DEC SDI-interfacessuch as KDB50 or HSC50/70.
I'm not aware of anybody having such a box. Is there anybody out there with such a thing, possibly in usage? What's your experience with it?
Anybody who would be willing to trad/offer one of those boards which fit into the SMDI-box? In that case, please contact me off-list.
Kind regards,
Pierre

Hi all,
I have a 9830A that I haven't powered up in a while.? Previously, it would take a few seconds to get to the lazy-T prompt, but now on powerup, the screen remains blank.? I got Tony Duell's phenomenal schematics, and was all set to start debugging, starting at the clock, but I checked the user manual first, and following the suggestion in the setup section, I hit "STOP", which brought me to the prompt, and from there, it appears to be functioning normally.?? However, the machine powers up this way every time--never to a prompt.??
Does anyone have an idea why the machine is behaving this way?? I'd love to have it power up to a prompt.
Also, does anybody happen to have schematics for the infotek bitslice processor?? I don't have one, but I'd be very interested in trying to acquire or recreate one.
Thanks,
Dave
I was recently helping a friend clear out one of his storage lockers and
found (3) Emulex TC12 controllers. They look to be NOS and are in
shipping boxes.
The manual is on bitsavers:
http://bitsavers.trailing-edge.com/pdf/emulex/TC1251002-E_TC12tech_Jun83.pdf
The board emulates a DEC TS11 Unibus controller. It functions in both
streaming and formatted mode, supports 800 and 1600 densities, and has
the industry standard Pertec interface for PDP-11 and VAX-11 computers.
It is compatible with all DEC software which supports DEC's TS11
controller.
If you are interested in one or more of these controllers, make a
reasonable offer - and I'll give you the owners PayPal address to
send the funds (or check if you're so inclined).
Regards,
Lyle

Hello,
I bought this complete Victor 9000 system from a local guy, mostly because he needed the money.
It powers-up and displays, but won't boot any of the floppy disks for reasons unknown.
I paid $100, so if anyone wants it, I will let it go for the same amount.
It includes the keyboard and monitor, all in the giant original box.It weighs 60 pounds, so local pick-up is preferred.
Thanks- Steve.

Actually, it wasn't that bad. The feel was horrible, but it was quite
reliable. I used mine as a freelance translator to translate several
fairly large books, as well as keeping my accounts on it and letting the
kids play games on it. I never had any problems with the keyboard.

That is a hard thing to determine. I'd say that shape and feel are both
important, as the shape of the keys can enhance speed and accuracy almost
as much as having a good mechanism.

Indeed. I kind of like the IR keyboard and it seems to work better than
what the press let on, but it does seem to eat batteries (at least the
chicklet one, not sure about the enhanced keyboard). I wouldn't want to
type a paper with it for sure. Still, I imagine this is probably a matter
of asking the right questions for a market survey. What, if any, detail was
the focus group privy to when the compromises to the keyboard were asked
about? Did they follow up afterwards? Seems like they probably didn't and
just ran with it.
The PCjr is kind of a neat machine in its own right, but I have to think
that it is caught between a rock and a hard place. On one hand, IBM wanted
to capture a chunk of the emerging home computer market, but on the other
hand not cannibalize sales from the more expensive (and more expandable)
IBM PC. It obviously had a couple of things going for it over the PC
(graphics and sound capability), but it was also more or less priced
basically smack-dab between the Commodore and Atari 8-bit offerings and the
IBM PC itself. In a practical sense the memory limitation made it about as
powerful as a C-64 or Atari 8-bit machine when accounting for tradeoffs in
custom chip capabilities vs a less powerful CPU in the case of the other
8-bit rivals. Most of the design compromises for it vs the PC seem
rational, with the exception of using BERG connectors for everything, which
is nonsensical to me. Well, that and the fact that IBM didn't offer
upgrades for a full 640kB RAM. I'm sure that the latter would have made it
a bit more palatable to people since the vast majority of PCs weren't sold
with 64kB ( or 128kB for that matter). From what I can tell, the DMA
restriction isn't too much of a problem in practical use, with the
exception of the serial port), so with just the additional memory it
probably would have enjoyed fairly good software compatibility with its big
brother.
Hi there!
Anyone on this list remember or ever used VisualAge Generator? I understand it was "replaced" with EGL, a completely unrelated system.
For the historically curious though, was a trial ever produced around the 4.5 version timeframe?
Thanks!

OK, Tony seems to push the buttons of a few people on here who don't get his
particular brand of humour/irony and are also not willing to consider his
circumstances and cut him any slack, but IMO this particular personal attack
is almost completely unjustified. I'm actually quite surprised since it
seems out of character for my left-coast fellow Canuck, for whom I've always
had a great deal of respect until this childish rant/personal attack; I hope
he's OK...

In the past I have participated in threads here about the DEC-modified
version of the ASR 33 Teletype, and the role of the Reader Run relay card
(part number 4915) for loading papertapes. I wanted to report that I have
been able to load BASIC from papertape using a stock ASR 33 on a PDP 11/05
without the presence of the reader run card installed. I did have to hit
START on the teletype to load the tape at the right time, but otherwise it
works just fine. I assume that the load does not require a lot of starts
and stops and therefore no need for the reader run. You don't know unless
you try, so now I know. I was also happy to find that BASIC remains in
core memory, ready to run from 000000 on my 8K system the next day, without
having to re-load the papertapes (abs loader and BASIC).
I have not yet saved and re-loaded a BASIC program but I hope that'll work
without the reader run. I would assume however that I'd need the reader
run for more complex operations like assembling programs. I have another
UCC-6 with the beginnings of a homebrew reader run that I need to complete.
If anyone has an actual 4915 for sale, I'd be interested.

They were certainly easy to clean underneath the keys if I recall
correctly (turn the machine upside down and shake gently and listen to
the pitter patter of falling keys :)
Of course since the original 520ST combined the mushy keyboard with a
relatively non rigid case and poorly socketed chips typing vigorously
could reset or hang the machine...
Can I put a vote in for whatever Windows mobile XDA disaster O2 were
selling a few years back... which did not support chorded keys? (You
want shift and a key? please press and release shift... *then* press
the key). Type a message fast enough and the initial character will

Ive decided to part with one of my OpenStep/NeXTstep Compatible Thinkpads
Its a 380ED with the following specs
166mhz Pentium MMX
48MB RAM, 3GB Hard Drive
Xircom IIps PCMCIA Ethernet Card
Running a fresh install of OpenStep 4.2 for Intel. Has a compatible
network card installed and video and sound is fully supported on the
380ED, So if you want a no frills OpenStep/NeXTstep box this is for
you. A copy of OpenStep 4.2 and NEXTSTEP 3.3 with boot disks will be
included with the laptop.
$125.00 shipped
I have an Apollo DN300 that's been sitting in the corner of my garage
which I would love to find a good home for. It powers up, and seems to
pass self test but does not respond to any keyboard strokes. I will
entertain any offers but if no one wants to buy it, I would be happy to
see it go to a good home for free (you pay shipping of course). These
were stand alone work stations and so it does not have a HD so you will
need another node to boot from. I might have a disk enclosure lying
around but you will have to procure your own ESDI disk. Unfortunately
this machine will NOT run on anything newer than SR 9.7.5. It will come
with a keyboard, but it is missing the space bar. I know, im making this
offer sound SO attractive! Here is a link to some pictures
https://plus.google.com/photos/112158735340501596756/albums/590547810466293…
Please respond to me off the list, if you're interested in more information.
Thanks,
Kurt
How about y'all stopping flogging this by now very dead horse?
If you don't want to fight via private email, then please don't do it in
public either. You are only showing the rest of the world how rude you
can be and how clever you think you are.
I am not addressing this to anyone in particular, because I do not want
to get involved, only to get you to stop making d**ks of yourselves in
public.
By all means say what is wrong or right in someone's schematic, but
please keep the personal attacks out of it.

Hi all. Remember this thread:
http://www.vintage-computer.com/vcforum/showthread.php?37642-NJ-USA-Large-l…
.....? Now it's time for we in MARCH to sell everything on the owner's
behalf.
Rules are what you'd expect: nothing's being tested; nothing's being
shipped; cash only; no parting out; no "dibs"; etc. .... you've got to
BE THERE or be square.
The following list is around 90% accurate. I might have mis-counted, for
example, where there are more than one of the same machine. Also, the
owner said there's a few other random items that will be available. And
last but not least, we in MARCH might grab one or two specific things
for the club collection; for example we might want one or two of the
Franklins.
Keep in mind, the Aug. 3-4 event is NOT the VCF East -- that's not until
next April -- this event is primarily a vintage computer repair weekend.
Entry is $10.

I have just pulled a heap of old Apple PowerBooks and Newtons out of storage, and have discovered that quite a few of the LCDs that were perfect last time I looked at them (some probably not for seven years ago now) have deteriorated to the point that they are no longer usable. Problems vary from big black splotches on mono screens, to colour screens with almost the entire display from the centre out showing only the backlight.
What are the causes for these kind of problems? Heat? Humidity?
They have been stored for the last six or seven years in a cool dry environment, but did spend one summer in a storage facility that could have reached 40 deg c at times.

Any of you old timers (or otherwise) know what these components were and
what they might have been used for? A keepsake from my wife's
grandfather's career with IBM. I'm guessing 1960s vintage, give or take.

There's an iMac (CRT-based) turned up for sale locally with a white / clear
pale-blue case; is it safe to assume that it's either:
A first-generation (or first-gen rev C/D),
An iMac SL,
An iMac DV/SE
... i.e. Apple didn't offer that case style/color on any of the later
systems, so it's got to be one of the earlier ones from around 1999/2000?
cheers
J.
I have scanned now one binder containing blueprints/schematics for the
HP 9810 and 9820. There may be more hidden somewhere in the archives. I'll
scan that, too, when I find them. I hope that I also have schematics
for the 9830.
For now, they are mostly single page TIFF images; multi-page parts are
packed into PDFs. As usual, they can be found on our FTP site:
ftp://computermuseum.informatik.uni-stuttgart.de/hp/98xx/
Enjoy ;-)

I'm writing an article on computer museums for www.destinationz.org/
They're everywhere -- once I started looking for them.
I knew about -- have toured -- Computer History Museum --
www.computerhistory.org/
And I recently saw a great presentation on The Living Computer Museum --
www.livingcomputermuseum.org/
But I hadn't known about American Computer & Robotics Museum --
www.compustory.com/
I wonder what other museums exist -- especially any with relevance to
mainframes -- so I'll appreciate tips/pointers and, especially, hearing
about experiences joining/supporting/visiting them. (Or contributing
artifacts to them. Maintaining private collections of mainframe
components as some people I know do is interesting but might not qualify
as operating a museum. My wife called one such residence decorated with
large mainframe components a "computer mausoleum" -- but I liked it.)
Too bad, I have no budget for world tour of museums -- so I'll have to
visit virtually.

Rather rough condition! No hard drives, the recyclers kind of tore them up
getting the hdd out of them.

Been away from the list for a while, but a recent discovery has
rekindled one of my classic computing projects I always wanted to do...
I have 3 tapes that I have re-discovered that came from my earliest
college days.
They have stuff from my days on a TOPS-10 system.
I have a DEC SCSI based tabletop tape drive to read these with.
What is the best way to image these, preserving their contents ?
Also, what software will put these in a format I can use with an
emulator ?
Does anyone know if any of the emulators can mount the tapes directly
>from the emulator through the SCSI bus ? Or is the only way to image
these in a format compatible with the emulators ?
Anyone know what the best emulator is for DECsystem10 ? How about
DECsystem 20 ?
Thank in advance,
-- Curt
A dealer just called me. He was one of the first 100 Apple dealers in the
US, and he has been sitting on original equipment since it was first being
sold. Collection includes Apple II, classic Macs, Atari, and original IBM
PC stuff. He would now like to sell off his collection.
Please email him your interests.

The recent talk about 7906 drives prompted me to post this. My wish
list includes a 7906H (preferably), or a 7906M (with 13037) would be
acceptable. Does anyone have one taking up space? East coast (US) would
be preferable.

The license comes from the VMS Hobbyist Program. It's good for any version of VMS, from 0.whateveryoucanfind to 8.4.
Even though early versions of VMS do not enforce licensing through the LMF, it's still required.
Media can be borrowed. HP doesn't care where you get it, but asks that it not be posted for public download.
I'm going to call this "classic by fiat", since Apple has decided
that it's "vintage" enough to have stripped most of the content
>from its website by now, though it's not clear that any of this
was ever easily available there to begin with.
I'm looking for any guides, sample code, etc. on developing OpenGL
drivers for Mac OS 9, since an evening with Google has proven
mostly fruitless. I've found plenty on developing OS 9 OpenGL
*applications*, but I'm looking for even just a reference for the
hooks that need to go into the driver. So far, I've come up
pretty empty.
I always have the option of reverse-engineering existing drivers,
since I have a copy of IDA Pro, but that's obviously a BIG time
commitment.
Anyone have such a thing in their possession or know to whom I
should speak? I'll be posting this on a few lists/forums.

Ken,
I noticed that you were looking for the manuals for these boards. Do you have an HK68/M140 and would you be interested in selling?
Thanks,
