Well, one of my old computers is the star in an upcoming short film called "Base Code." It's a 1980 Radio Shack TRS-80 Model III. I made a little documentary. You may not want to watch all 20 minutes, but definitely watch the last 2 minutes. Look for me in some places too! http://gallery.me.com/dgreelish/100077

I find myself in need of an oscilloscope to help me fix my PDP11 PSU (I am
being ably assisted by a member of the list, so don't worry). As this is for
occasional use only I can't justify spending a lot of money. From previous
postings on the list I think I need a minimum spec of dual trace and 20MHz
bandwidth.
Does anyone have any recommendations for what to buy? I suspect it would be
better to get a higher quality used one than a cheaper new one. Perhaps
someone in the UK on this list has one they want to sell?

The RetroComputing Society of Rhode Island is doing some
housecleaning, as we need to make room for a new machine (a Cray J). I
will probably offer up some goodies here and on Ebay over the next few
weeks. I might even throw some of the Joe Heck stuff in as well.
We have a couple of MDB Qbus chassis - no cards. Pretty basic 3rd
party DEC stuff. These are rack mount, and are roughly equivalent to a
PDP-11/23.
We would like to get anything over shipping for these. Additionally, I
could probably deliver to any of the NY area hamfests, or even at our
open houses in Providence, RI (generally 3rd Saturday of the month).
We will also have a massive triage of u-fixum VT100s soon. Those will
likely be pickup only.
All proceeds over shipping will go to RCS.

Has anyone ever seen either of these? They're introduced in the Tektronix
catalog for 1973, pg. 277. I cannot find pictures of either of these
peripherals in any catalog. The cassette drive appeared in only the
1973 catalog and the tape punch/reader appeared for only three years.
Prices:
4911 4912
1973 $2950 $1950
1974 $2950
1975 $3295
I've collated together all the graphics/terminal products from the
various Tektronix catalogs together into a single PDF file:
<http://www.xmission.com/~legalize/vintage/docs/tektronix/Tektronix_Terminal…>
This includes the storage scope displays and related equipment, but
omits all the oscilloscope, test equipment and microprocessor development
system stuff. It does include the workstations, however.

A friend has a well preserved IBM 3430 tape drive (off an IBM
System/38) and we speculated whether we could connect this to one of
our AS/400s, which we understand is possible via a suitable SPD card.
Before we try to usually difficult process of negotiating down the
high prices offered by various eBay sellers, does anyone have any
surplus bus/tag cables and terminators (for both) which they can offer
please?
Here are pictures of the IBM 3430 and most of the cables etc:

Hey is anybody running INN, especially under Solaris 10?
I am using leafnode under Linux and I'm mostly happy with it but I'm
thinking about moving this service off my desktop and running it on a
server, probably under Solaris 10. I figured while I am at it maybe I
should consider INN because of the option of using a different spool
format that is supposed to increase performance significantly. Recovering
or moving my news spool which is not that big at around 4G takes forever
(not that I do it a lot, but I have done it and it's a pain) and now the
startup each time a client connects takes a while. I think I'm outgrowing
leafnode.
I'm curious how much work it takes to administer INN for a small network to
know if it's worth it or just overkill. Specifically, I want to be able to
only host groups I want (about 500) including local-only groups rather
than doing a complete usenet grab, and I would like to be able to support
SSL connections directly. I use stunnel now on Linux but I've had some
problems with it on Solaris 10, so if INN supports it directly that would
be a plus.
If anybody has any comments or suggestions I would appreciate it. Thanks.

For those of you like me who run a decently sized home server network, I am
unhappily having to leave DSL Extreme (who have treated me pretty well)
because the new house, despite having AT&T, is apparently not in their service
area.
I'm trying to find a new DSL ISP that serves Southern California that offers
at least 5 static IPs at a decent rate (6/608, etc) and does not block ports
as I run a mail server off it. Nationwide ISPs are fine if they are good,
better still if I can prequal and compare rates online.
So far rejected Speakeasy after the Covad/Megapath debacle. Now looking at
Linkline, Pacific Internet and Keyway.
Please reply offlist since this is super off-topic. :)

Hi,
I have an HP 3000 Corporate Business System (3000/996) with 12 CPUs
and 1 to 2 GB of RAM, in 6' rack that I'd like to find a home for.
It runs! The A/C power plug requires the weird hi-amp 3-prong outlet, not standard household 110.
It's in Cupertino, CA, and is housed in a 6' rack (included).
(Sadly, it qualifies as a classic, probably from about 1997.)
If no home is found fairly quickly, it'll be scrapped, unfortunately.

There's some SGI servers out at NASA (Langley, VA) on gsaauctions.gov
if anyone feels like bidding on them. Opening bid is like $25-35, so
definately a bargain. one lot has 2 Onyx 2 cubes and another lot has
an Origin 2000 rack (could have graphics, hard to tell).
I'd bid on these, but trans-continental freight shipping is
prohibitive these days and the purple cubes are definately sensitive
to handling.
Hopefully someone out on the least coast will snatch 'em up.

I'm interested. That certainly ties together several fascinating
threads of 'classic' computing.
Does anyone have the pinout for the cable that goes from a DEC LK250
keyboard to an AT DIN or PS/2 keyboard plug?
I've got an LK250 that is missing the cable. There's a 6-pin modular
jack (standard not MMJ) on the keyboard and I presume the missing cable
has a mating modular plug on one end and a DIN or PS/2 plug on the other.
I can make one if I can find the pinout...

I was at a local scrapper talking about copper, and saw a a tek
565-RM. had 1/2 the slides, was stored indoors, and I didn't see it
last week when dropping off batteries, so it could be fresh from the U
of I. He wants $100 for it ( seems high to me) and it weights about
75#s. If anyone wants it, I can get it, and possibly box it. Shipping
would be expensive, unless you are close or someone in doing a road
trip. I can store it for a few months. . I also have a box up plug
in's for these, maybe 10-12. If anyone wants, I can did them out and
make up a list. I used to have a few 555's, but I do like the new
smaller units

Pretty much all Spheres were prototypes - NONE of them worked properly

They were crap, plain and simple.
Interestingly, just a couple of days ago, I was informed that the last

I picked up a two-port parallel card for my Lisa 2/10. Unfortunately, it
fails the POST diagnostics with error '92'. The system does correctly
identify which slot it's in, FWIW.
Does anyone know what the system firmware is poking around for? Is it
asserting a checksum test on the card's EPROM? Checking for an interrupt
response?
The label covering the parallel card EPROM erase window is long gone, so
I'm wondering if it was left in the sunlight and partially erased.
Does anyone have an image of the EPROM?

Greetings,
I have a friend that is looking for a DN4500 or DN5500.
Unfortunately he is in the hospital right now. He had a serious case
of spiral meningitis and has been unconscious for a week. The doctors
are pulling him through!!!
I'd like to keep in touch and maybe he will be interested in a month
when he is recovered.
He has a DN5500 that was fully intact, including a cartridge drive,
but the clock battery leaked acid on the motherboard and it will no
longer work. But the disk drive, RAM, cartridge tape, etc. all
work. So making a binary image of the tapes seems possible.
Both of us used to be Applications Engineers for Mentor Graphics :-)

I haven't come across a model 20e but I would have expected SHOW MEM to work.
Try T 50 - hopefully there should be a number giving the memory size in hex
just below the line starting with MEM.

Hello all,
How do I determine the installed memory in a microVAX 3100 Model 20e?
The unit has no disk in it presently. It starts healthily though and talks to my VT420, although it doesn't seem to run many diagnostic tests compared to what I'm used to seeing on my 3100 model 90. It also doesn't report the amount of installed memory and SHOW CONFIG / SHOW MEM / T 9E produce "ILL COMMAND".
Can anybody help?

For my final year engineering degree project, I co-wrote a Z80 simulator in
somewhat pre-FORTRAN-77 to run on an IBM 4381 running MUSIC (under VM). The
college planned to use this to teach students about microprocessors but I
don't know if this was ever done.
Not having much use for a Z80 simulator myself, I later rewrote it as a 6502
simulator and then converted the core of the simulator from FORTRAN to IBM 370
assembly and later still, VAX assembly. It can run the BASIC rom from the BBC
Micro but not the OS rom. Instead some mainly text based OS functions are
emulated/simulated directly. Software such as text based adventure games for
the BBC Micro can be run on the simulator but anything relying on graphics,
sound or trying to play directly with the hardware doesn't do so well.

Apple II Concert
Saturday, June 25th, 2011
6pm: Meeting of the Apple II owners/musicians
8pm: Concert
The old Apple II, first introduced in 1977, was a revolutionary computer in many ways. Sound capabilities were not one of them. The Apple II?s sound system, unlike contemporaries such as the Atari 800 or Commodore 64, did not use a discreet sound chip, but rather a simple timer circuit that could be coaxed into creating square-wave tones. Most chiptune musicians tend to use sound-chip based systems, but there is a certain charm to square-wave tones. Some may define this charm as ?annoyance.?
So, as a grand ?musical? experiment, noted loon Jason Torchinsky has written a crude 16-step sequencer for the Apple II, and is seeking to gather up as many Apple IIs as possible to construct an orchestra which will then perform a live, dynamic concert/musical event. Machine?s resident music guru, Chris Kallemyer, will be on hand to discuss the nature of music, why some of the Apple?s 256 tones are notes and some are not, and generally help make things somewhat listenable.
Who knows what the end result will sound like? A chorus of angels, poking at touch-tone phones? All the computers from the background of every sci-fi movie from the 1950s-80s going off at once? A serenade by a truckload of R2-D2s? Come on out and listen for yourselves.
We are currently seeking Apple II owners to contribute to making this happen! Please contact machine at machineproject.com if you would like to participate!

Minor British Institutions: Izal toilet paper
By Sean O'Grady
Saturday, 4 July 2009
It is a discomfiting thing to learn that Izal loo roll is still
available. Not as discomfiting as it used to be, in the days when this
slightly abrasive product was routinely found in school toilets and
public conveniences, the harsh price of spending a penny away from
home. Today it is not ? quite ? so harsh.
San Izal has been rebranded Izal, and the tissue seems less
unforgiving than before. Make no mistake, this is not the sort of roll
that the Andrex puppy would like to romp around with, but it is just a
little less austere than before. The scent of disinfectant seems also
to have disappeared, which is a bit of a shame for those who like
their khazi karma nice and traditional.
It is difficult to believe that, in a world of ultra-soft pastel-hued
lavatorial opulence, such a throwback to the age of austerity will
still be bought out of choice (it is not particularly cheap either).
Some websites market it as a "novelty product". Nostalgia, surely, has
its limits: there's no need to scrape the bottom of the barrel. "
It would wrinkle into sharp points and hurt ones delicate behind. I
could easily see a printer being able to use it.

I'm fascinated and a little horrified by this. Was there really a teletype
that could print on toilet paper without shredding it? Or is it that the
US Government in the 1950s made its employees use TP that was tough enough
to survive a run through a teletype?!?! Egad!
Hi guys,
A couple of hours ago, I found a copy of some old presentation slides I
put together for the "pre-release" DiscFerret which was part of my MEng
project presentation. They cover the basics of magnetic data recording
(on floppies only, this is before I added MFM HDD support), and how the
hardware works.
So how about this: a short series of DiscFerret presentations, done on
Ustream or Livestream, explaining what it is, what it does, how it
works, and how to make it do useful stuff. This would be both from the
point of view of a user (DF-LUA / Arthur toolkit) and a programmer
(LibDiscFerret API).
I was thinking something along the lines of a half-hour (or so,
depending on subject matter) presentation, followed by about 20 minutes
for Q&A.
Now for the Million Dollar Question: would anyone be interested in
something like this?
Thanks,

When I went to university in 1976, everybody got a calculator. There
were two models which sold the most: the TI-57 and the HP-25, virtually
no other makes were sold at all. They were essentially equivalent, the
TI being rather cheaper but faster. The odd HP-67, SR-52 or TI-59 sold
as well, although you had to have rich parents, plenty of savings or
mortgage parts of your body to the devil to afford one. HPs were
considered the BMWs of calculators, the TIs were the Fords :-) I got an
HP-25 which I never regretted, the extra money I spent probably gave me
a couple of extra years longer life thanks to less stress using it,
owing to RPN.

AFAIK compilers often/usually convert expression to postfix notation
(RPN or close) during parsing.
Also of course the Burroughs B5000 series and successors (up to B7800
IIRC) were stack machines, using postfix notation internally.
At university a calculator was a necessity, I had an HP-25 and I always
found that RPN made it a lot easier to keep track of where I was in
complex calculations, e.g. when working out the reactance of some
series-parallel-whatever network of R, L and C. The equations usually
barely fitted on one line of a sheet of notepaper, involved lots of
additions, subtractions, divisions and multiplications and conversions
between rectangular and polar coordinates, and I did not envy those who
used infix calculators.

Does anyone know who owns this list and how to get in touch with them? I
joined last month, made about three totally innocuous postings and found
myself banned at the next attempt to sign in. Google, in their infinite
wisdom, gives you no means to find out if it's a mistake, appeal to the
owner, or even get an explanation for why it's occurred!
I sent a message to the posting address with no response. I had been
given the name of "lowenddan at gmail.com" as list owner, but cannot get any
response from that address either.
Is there something I should know about becoming worthy of Lisa List
membership? Perhaps a secret handshake I've overlooked? I contacted a
couple of members privately, and both were utterly baffled as to what the
motivation may have been.
I'm still operating on the assumption that this is a software glitch or
mistake. If I've been thrown off as a deliberate action, then I think
it's common courtesy for the list owner to at least explain why this
occurred.

I recently acquired a MicroVAX II in a BA123 (World Box) enclosure. It has
cleaned up really well. The only niggle is that I am missing the little door
that goes over the front panel at the lower left of the enclosure. Does
anyone have one of these going spare?

Not sure how far you're going back but...
Mains filters from the 50's and 60's likely had
paper/wax capacitors in them. At least in the US,
there doesn't seem to have been a special rating
system for these but most cap failures were benign (not
purely luck... even though there was no special rating
they were generally made to be on the robust end.)
"Modern" ones (70's onwards) have specially rated X1,
X2, Y2 capacitors. In small filters these are likely to be
ceramics and in larger ones (especially snubber
networks) they are more likely to be boxed film capacitors.
They all have special fire protection and surge voltage
ratings. They do not necessarily lead "Easy" lives - if
some nearby inductive appliance is putting crap into the
power line, it's the small devices on the same circuit
or nearby branch that may end up eating it.

Picked up the intel 330 and 380 today, thanks Vince. However I think I
am not going to keep the rack. It is a 6 foot communication rack mount
case with a dark glass door and the Gandalf logo on the front top, on
wheels.
I could deliver it in the Portland Oregon area on Monday as it is in
my van at the moment. I want to keep the rails for the 330 and 380 but
can leave the power distributor if whomever takes it wants it.

Has anyone ever tried to color match spray paint to the DEC "taupe"
color (ie, the color of the front of a {clean} RL02)?
I've got a bunch of stuff now with scratches and rust which I'd like to

Is there any sort of standard color code for that DEC color?

This is a single channel oscilloscope and contains valves. The trace drifts

Interesting. If you look at the daughtercard on the PDQ-1000 (next to
the probably-a-pentium-ish-CPU-fan), it looks pretty much like a PC/104
connector (upside down, of course) and the back panel port config is
oh-so familiar. I'm betting a bog-standard embedded X86 system (new
enough to have PCI) with a QBus interface running an emulator.
As to the PDQ-2000 and -3200, I bet those are just Intel motherboards in
a rackmount case. Chris Elmquist pointed out the CCI1016 looks (to me
as well) to be a Comtrol RocketPort. The CEI-1000 is pretty clearly one
of the myriad of Intel desktop Ethernet adapters. Their DQP-1100, -1300

Hello there,
I live in England and own an old Commodore CBM Pet 8032 computer. Ten
years ago it was working fine and today I was clearing house and decided
to turn it on before trashing it.
It did come to life but has lots of unrecognized characters at bottom
half of screen, and when I type anything on keyboard it mostly replies
with "?SyntaxC13" or something of this nature.
Is there anywhere in the UK you know of where people will be interested
in this machine ? As it doesnt appear to be working correctly, I have
no real wish to "Ebay" the item.
It would be a shame to throw this out.
Thanks,
Paul.

Reino was an instructor at Cal Poly SLO when I was studying computer science

He was a nice old guy. I learned 360 BAL from his class. I think he passed

Bringing this back more on topic (but still not exactly about "classic" computing):
2011 Isaac Asimov Memorial Debate on The Theory of Everything
http://www.youtube.com/watch?v=lYeN66CSQhg
That is a fantastically interesting symposium to watch in its entirety, but these parts relate to reality as a computer simulation:
Dr. Jim Gates at:
0:09:20 Who he is
1:00:21 What he's found
1:34:15 More specifics about what he's found (binary error correction codes in string theory equations)
In the Science Channel show Through the Wormhole, another scientist found that certain characteristics of quantum mechanics can be explained by reality being a computer simulation. He noted that within the next fifty years, the computational power of the human brain will be available in a laptop that consumes the same amount of power or less and that this rate of growth in computational power far exceeds evolutionary increases in the human brain size/computational power being limited currently by the size of the birth canal. He extrapolates that process over billions of years to posit a higher intelligence programming a mega-computer to create our reality. Wild stuff to think about.
In another Science Channel show on the nature of reality, I believe it was stated that a room-sized quantum computer may have the power of a conventional computer the size of the universe. As a result of this and the limitations of growth in biological computational power through evolutionary means (although biological intelligence created in vitro may be a means around this once we actually understand the nature biological intelligence), the most likely form of an advanced technological civilization would be a computer with AI. So, any ET civilization older than ours that we'd contact would most likely be AI.
Dr. Gates stated in his introduction that Asimov's stories had inspired him to become a scientist. Here's one of them that follows the above conjectures, a story which blew my mind when I read it as a youngster:
The Last Question by Isaac Asimov

That's an importantly profound observation about the question at hand. Considering the idea of 'least hypothesis', the idea of a consciousness behind the nature of the Universe - i.e. God - seems to be far more straightforward than the mass of conflicting hypotheses to explain the origin of the Universe and the (known) life forms within it. Taken one by one, and within constraints, many of those hypotheses do make sense - for instance, the idea of natural selection. That makes sense as the dynamics of a working system. But the origin of the system it assumes as its basis is not well explained by that same hypothesis, nor are apparently 'disruptive' events within it, e.g. the rise of human-order intelligence (or even the existence of higher-order life).
Unfortunately, 'belief in God' is too often tied to 'belief' in a lot of other stuff, much of which seems to be contrived to ensure that those who work in the business of Organized Religion don't miss any meals. That tends to give it a bad name, especially among thinking people.
I will argue there's a difference between 'unsupported conclusions' and 'faith.' The latter is more similar to selection of a set of axioms. Axioms are exempt from proof (although showing one is invalid is good for nuking anything premised thereupon), but should be atomic in nature to be useful in logical discourse. Once you show a proof for an article of faith, it enters into the realm of 'known facts.' Unsupported conclusions seem disjoint from the realm of 'known facts' and even from that of 'faith,' assumed to be self-evident without a supporting framework of axioms, hypothesis and logical process. (See, social conservatives.)
Given the nature of this discussion, I'm going to the effort to make the following disclaimer: the above is my personal opinion and does not represent the official or casual opinion of my employer. -- Ian
Guys,
I used a Cambridge Z88 for Retrochallenge last year (see
http://www.retrochallenge.org for last competition) whilst on holiday.
The summer challenge runs in the month of July - entries will be welcome
anytime by email to me mark at wickensonline dot co dot uk.
This year I'd like to use a different, portable computing device to
document this year's summer challenge, and possibly include a little
programming.
My criteria are:
* no larger than a Cambridge Z88.
* daylight readable screen.
* operates on batteries.
* preferably with some kind of programming language/environment.
I'd welcome suggestions from members of the list as to what I could take
this year that would be fun to explore but also practical enough to use
day to day to write text for the website. I will take a laptop for
uploading text via wifi, so some sort of PC connectivity is a must
(although this could be as simple as an RS232 cable).
Many thanks, Mark
A couple of the items we "saved" this weekend from the garage in MN
included both an RX01 and an RX02 floppy system.
Unfortunately, the mice got to the RX02 before we did and really had
quite the palacial estate inside the cardboard box with foam packing
that held the unit. Needless to say, everything that comes out of a
mouse pretty much covered this drive system. Mouse effluent #1 turned
the whole thing to #2. It looks to be a total loss.
However, the RX01, in another box, was tightly wrapped in plastic
and appears to have survived. Also obtained were a spare set of RX02
"formatter" boards, which are the electronics that go in the chassis
and sit above the drives.
Does anyone know if a pair of RX01 drives and power supply can be
converted to an RX02 by just changing the formatter boards in the chassis?
Were the drives themselves different? or did they get to double density
by just changing the formatter?

On some occasions if running VMS, ANAL/ERROR can have useful tidbits. (Or ANAL/ERROR/ELV TRANSLATE on newer versions of VMS. Or DECEvent/Diagnose.)
But... it's just an AS1000. Flaky memory and/or flaky sockets and/or crappy power supplies will be the majority of failures.

So, me too. :-) I was first licensed back in 1972 and let it lapse about ten years later, but all this talk got me motivated, too. Unlike Dave, I missed the Extra exam (by only a point, they told me), but I did earn a General class ticket. I'm waiting for crystals to bring up my HT-220, a true "nostalgia toy" as I used to work on them back in the late '70s, and in the meantime I've been working some SSB on 40 and 20, and playing with a 2M handheld. I was going to restore a Drake B-line I picked up a few years ago - again, out of nostalgia for these outstanding radios - but in one of my few eBay transactions where I was snookered, I ended up with a radio that looks like it sat in someone's carport for a few years. After working on it for a bit, I decided it's "a bridge too far" for my available time and patience, and I picked up a Kenwood TS-430S through Craigslist.

I have had a fair amount of grief with my AS1000A machines but I wouldn't say
it was much more than my other DEC machines which all have their own share of
problems.
Do you ever get a real crash complete with crashdump? If so, analysis of the
dump may help pin down the problem. If not, there might still be something in
the error log.
It may be worth making sure the CPU board is seated correctly in its slot - I
have had issues with this and I assume the AS1000 and AS1000A are the same in
this respect. As far as I can tell the main difference between them is that the
AS1000A has more PCI slots instead of (E)ISA slots.
The B-Cache on the CPU board seems to be prone to failure, however it usually
shows up in the diagnostics. It can be disabled by moving a jumper and the
machine will run with reduced performance. (The memexer diagnostic will then
spectacularly fail as it appears to divide something by the cache size...)
I've also had memory failures but these also showed up in the diagnostics for
me (sometimes the diagnostics seem to report the wrong slot as being faulty).
However, I've also seen memory problems in other alphas cause random hangs
while nothing shows up in diagnostics. You could try running with a reduced
amount of memory.
As with any machine, it is worth checking the the power supply voltages
are correct and don't have excess ripple.
Right now, I've got one that used to randomly halt and now randomly switches
itself off. I suspect problems with the front panel switches or related logic
but I haven't worked up the enthusiasm to check this theory out.

Is there something like MAINDEC for Alpha?
I have an AS1000 that randomly goes catatonic and I'd like to try to narrow down what's going on.
It will do it shortly after boot, usually within 15 minutes, and won't run for longer than an hour at most.
Sometimes it hangs hard and must be power-cycled, sometimes it crashes with random messages.
The SRM diagnostics say nothing is wrong, even when run for very long loops.

Hi all,
I have a DECServer 90L+ that I am trying to use as a terminal server.
After some time, I managed to get it powered up and started to look
for MOP boot requests. However, the expected, give me a MOP boot image
broadcast on the network did not occur. The Ethernet frames that I see
give the impression that the DECServer is looking for a specific
machine on the network. I am also not getting any output on the first
serial port (MMJ to MMJ cable connected to a VT320)[1].
So, first question. Does anyone know how to do a factory reset on
these. The operating manual isn't much help. :(
Oh, I am considering it a success so far in that I got it powered up
and saw Ethernet traffic from it!
[1] I haven't checked my MMJ cable for continuity yet.
Many thanks.

Possibly a bit modern for folks on here... ;?)
I've just bought 1 cheaply on eBay (under ?15) and am considering a
2nd as a cheap way to get some additional storage for it. The device
has 3 proprietary card slots, 2 for RAM or Flash, 1 for an EPROM.
I was wondering if anyone had devised some device to let owners use
much cheaper modern Flash storage in 'em, such as CF or SD cards?
Given that they've been interfaced to Spectrums and so on these

Oh ye of little faith. Tymshare made LOTS of RS232 capable ASR-33's.
They had a mod kit that they used along with the OEM call control unit.
It came in several models. The early one (circa 1968) had a small transformer (to make the proper voltages) and a control board with a relay to turn on the motor when CD (pin 8) became true. It preserved the Local/Off/Line switch function (the rotary switch on the call control unit). A later version used push buttons on the cover plate that goes over the CCU section of the ASR/KSR-33. They replaced the Line/Off/Local rotary switch on the "front panel" that was subject to knob breakage (usually a panicked service call). The front escutcheon that had the hole for the Line/Off/Local switch was replaced with a nice Tymshare enhanced logo snap on plate that looked nice.
My (at the moment lost or trashed) ASR-33 I did my own RS-232 conversion. It consisted of taking taps off of the transformer of the CCU (to get the other voltage) and including a nice solid state relay to do the "Carrier Detect" function for motor control. It required only a couple of transistors for the receive (RS232 to 20ma CL) and resistor tree for the other direction. Having a RS-232 capable ASR33 was a real nice thing to have when most of the connectors were DB-25's.
On another note: I do have a couple of old DECWRITERS. An LA-30 (modified for lower case) and a larger wide carriage one that I don't remember the model number (upper and lower case as well).
Ah yes, fun from the past....
Is it possible to change a 6P into a 6MP by adding a Postscript SIMM?
If so do the RAM and PS from a 5MP work in a 6P? Just wondering
about 6P I picked up as a spare, as my current Laser is a 5MP (and I
like the PostScript capabilities), I figure it's good to know these
things ahead of time.

The Rhode Island Computer Museum has a Wang 6230 CPU in a VS5700
10-slot chassis along with four SCSI controllers and terminal
controllers. That probably makes it close to a VS6230. The model for
GENEDIT is a 6128.
https://sites.google.com/site/ricmwarehouse/Home/equipment/wang-vs6230
The system was donated without the internal SCSI drive. We have plenty
of SCSI disks that we can install, but we don't have the VS boot
floppy or disk initialization utility for this system.
Does anyone know where the diskettes for this system could be located?

I have used TECO on and off for 30 years (mostly
off for the past 15 years). The latest version that I
can find which was released for RT-11 is TECO
V36. This version was released with V04.00 of
RT-11 in 1980. The TECO command "EO="
confirms that the version is V36.
About a year ago, I found some source code for
TECO V36 which assembles to V36 when asked
via "EO=", but the TECO.SAV file is significantly
different from the version released with V04.00 of
RT-11 in 1980. The version based on the source
code that I found is 51 blocks long and it uses more
memory. The version from RT-11 V04.00 is just
50 blocks long and has a much smaller root section.
Probably most of the code is the same, just that
some of the code that is in the root of the version
for which I have the source has been moved to an
overlay.
Does anyone have or know where I might find the
actual source code for TECO V36 that was released
with V04.00 of RT-11 in 1980? If it is just almost
identical, that would be sufficient since it is usually
possible to easily make a few modifications to obtain
the identical TECO.SAV when the differences are
minor. Often, the differences seem major since they
can be the result of a single extra word (plus or minus)
which shifts the rest of the code and makes an exact
comparison impossible. But those changes are easy
to find and correct if the knowledge and experience
of what to do is available.
Since the TECO V36 released with V04.00 of RT-11
is now 31 years old and I have not heard of any bugs,
I have much more confidence in its reliability as opposed
to the version for which I have the source code.

During cleanup & preparation for reducing my collection, I came
across a small backplane with small flip-chips and marked 'DT-03'.
The backplane can be mounted horizontally in a rack.
The DT-07 is a single card with 3 berg connectors which apparently
go to the 2nd card which is named 'DT-07 connector/terminator'.
Anyone know what this is?

Hello
The museum has been donated a complete ATEX system with all of it's
supporting parts. I will be flying into Salt Lake City either late June
23rd or early June 24th to rent a truck move everything to a storage
unit there and we can move it to Houston yet (low funds). If anyone
living in the area can help it would be really great. Contact me off
list if you can help.
Thanks,

I'm trying to recondition a metal front panel which is white with black lettering.
?
Some of the controls have boxes drawn around them in black, and on one of
the boxes, the black line has faded away.
?
I'd like to repair this, and wondered if anyone has any suggestions. The line is
about 1mm, possibly 2mm?wide.
?
I've tried a quality marker pen, but the ink doesnt 'stick' to the panel, also its
not a clean enough edge on the line.
?
I'm thinking that something like lettreset might work - the line is only about 5cm
long (or 2" in old money).
?
I havent managed to find anyone selling 'lines' though, just letters.
?
Any ideas?
?
Thanks
?

HI,
A couple of months ago there was somebody looking for a replacement core
board. I apologise for sending to the list, but I have lost the email.
I have one - condition completely unknown, but at least the cores appear
intact - and still covered by the perspex shield.
It is available for shipping - I am in Australia.
It is identified as a 8K x 18 array.

It's easily many months off, but when I do bring up that machine, I'm

[cross-posted to the hercules-os360 and midatlanticretro lists due to
relevant references]
Due to all the stuff going on lately, there have been times over the
past few weeks when I've needed some therapeutic hack time. I dug up
the source code for the Berkeley SPICE 2 analog circuit simulator, plus
the assembler assists for IBM 360/370 mainframes. SPICE 2 is written in
FORTRAN IV, but it requires assembler assists for a few things, and they
must be provided for whatever architecture and operating system you're
porting it to. (well, C under UNIX, but assembler on most everything else)
The 360/370 assembler assists were written for the VM/370 operating
system; they use the DIAGNOSE interface to CP for TOD clock access.
While I do run VM/370 from time to time, most recently I've been pretty
deeply into MVS.
So, I rewrote the assembler assists for MVS, wrote the small pile of
JCL required to compile it all, and got it working today. I'm now
happily running SPICE simulations under MVS 3.8J on an emulated (via
Hercules) IBM 370. This required learning lots of new stuff, which of
course is the best part. Now I know a lot more about 360/370 assembler,
how to call assembler routines from FORTRAN and pass data back and
forth, and how to compile/assemble and link multiple modules into a
single executable via JCL.
I've not yet tried it under OS/360 MVT, but I will soon.
I hope to eventually be able to run this on my real System/370 at the
new building in PA.
