Hello all,
as I'm trying out some "new" old computers I got during the last few weeks, I'm of course encountering new problems. I have spent some time with search engines without major success, so I figured it would be okay to ask here.
Case one concerns the SGI O2 workstation. I pulled three of those out of a dumpster; they only had a piece of the blue case plastic left on top and the base trays were broken as well - even the CD bezels are missing. The chassis look pretty battered but the machines power up, play their happy notes and enter the resident menu. Each has one disk tray but the disks were probably ruined by being flung into the container. They also all have an A/V module with the O2cam connector in the back panel. The connector is broken in one of them and I'll probably remove it altogether since I don't have a cam anyway but... the S-Video and Composite I/O jacks in the side panel are covered with a square sheet of textured self-adhesive plastic. The PCB silkscreening states they are Moosehead A/V modules and it looks like no major components are missing from the boards so I hope the video I/O will work once I pull the stickers off?
TIA,

I'm chiming in very late and probably not very helpfully, but is
there any way a decoupling cap in the vicinity of the FPU/CPU could
either load them or generate heat itself by beginning to short to
ground? My only VAX (4000VLC) had a fault like that in the reset
circuit which would sometimes hold it in reset, as you may remember

Don't know where the 12K is going to - maybe address space reserved for

almost exciting reading!
This message is for Mike McFadden.
Mike,
I came across your message while looking for a replacement for my informer 207.
What info are you needing. I think that I have a photocopy of the
manual around here and a few other pages of info.
Your message said you had 2 of these terminals.
Would you be interested in selling one? If so, at what price.
The one I have just died and I need a replacement. I use it as a
serial terminal on an old SCO Xenix computer, that has been running since 1984.
Thanks
Stephen

I have heard of something similar called "Mocha SMB" which at least would have been shareware, but have hitherto been unable to find it anywhere. This would perhaps be my best bet.

The data is still backed up somewhere else and the OS 8 drive was a fresh install so there's not much to worry about (and yes, I have installed and moved SCSI hard drives in several sorts of machines and enclosures...) but I don't yet understand why I would need a commercial product since OS 8 rather clearly states that it is able to use DOS formatted media - but doesn't go out of its way to point out how (the help "wizard" gets hung in a loop where it repeatedly asks me to select the volume I want to format although it already is).

Two nice ideas for which I might actually even have the hardware (dunno if an iMac is going to take OS X and my HP NetServer LH6000 would be a bitch to set up because it's so huuuge), but both depending on additional commercial software.

The OS 8 install includes Netscape 3.something which just might work as an FTP client, and WarFTP is free, so this is probably what I'm going to try next.

This is what I was already trying with that hard disk, but couldn't find a format which both machines could use.
Resource Forks are of no concern since the stuff was all generated and used under Windows until now.

I was watching "How It's Made" on the Discovery Channel this morning,
and they were constructing speakers. As they went to magnetize the
ferrite ring, I noticed the operator working with an interesting
three-button control panel.
The button he pressed was a red "Fault" light/button. To their left
was a beautiful white "Ready" light/button, and one marked "Write
Protect". This strikes me as a very interesting magnetizing
apparatus.

my high school got one in 1971 and through the punch cards, you could get to binary &, |, and shift commands as well as program jumps. I have a complete one in a box with reader, manuals, unused punch cards, etc. It was an eBay nostalgia buy a few years ago. One of these days, I will be organized enough to have it on a table to play with it. It was always fun to see the flashing nixie tubes as it ran calculations.
As to the tech inside, I would expect that it was a multi-LSI "big" chip dedicated calculator design, so any memory was probably implemented as registers in the chips. JUst a gues anyway.

I pulled out NETBOT:: a 12mb uV2000 with a RD53 and booted it with the
case off to get the temp and the hotter of the two chips stabilized
at 58C +- a tiny bit while running VMS 5.4-3.
Like I said they do run hot.

My second question concerns data transfer between (Windoze) PCs and Macs. I got a Power Macintosh 7200 (with Mac OS 8.0) which I would like to move some data to (approx. 3 GB); filesharing over Ethernet doesn't work without additional software since the Mac doesn't understand SMB/CIFS and W98/2k (not Server)don't understand enough AFS. "Web Sharing" only supports the opposite direction (PC can read data from the Mac) unless I'm missing something.
So what I'm left with is pushing the stuff onto an idle 4GB SCSI disk that I can then hang off the Mac. Unfortunately I couldn't get an idea how to accomplish this: if I format the disk on the PC, the Mac will come up with "Uninitialized Volume". Initializing the volume as "DOS 4GB" doesn't work, the same dialog comes up again after I restart and going back to the PC I can even still read the contents! I tried one FAT32 partition (primary) as well as two FAT16 drives inside an extended partition.
Thanks in advance, yours sincerely

Hi Guys,
I've just acquired a VAXstation 2000 (thanks Mouse!) which exhibits what appears
to be an overheating issue.
Powered up ir runs for about 10 mins or so (just sitting at the console prompt
doing things like TEST 50 to display the configuration, pressing ENTER to get
another '>>>' etc.). After about 10 mins (give or take) it fails, sometimes
appears to reset, hangs etc.
Firt thing I noticed is that the two surface mount chips with the round heatsinks
affixed to them get *HOT* ... Hot enough that you wounldn't want to keep your finger
on either of them for very long.
I believe these are the CPU and FPU chip? - Is this normal for them to run this
hot? They don't heat up alarmingly quickly, but after a few minutes they are
hotter than I'd think normal.
Aside from the eventual failure, it seems to run correctly - the self tests
(including the FPU test) pass (except for those which don't have hardware installed,
loopback connectors etc.
When I got the system, it was jam packed with cards, including the main board,
color frame buffer, double-sided memory expansion and an ethernet interface.
During my testing, I've removed all of these except for the main board, and am
running the system as a MicroVAX. I do have the resistor/loading card installed
as is recommended when running the system lightly loaded.
Power rails all look good - There is a 9V supply which the technial manual
describes as "for loading" which has a separate supply and return. Relative
to ground I measure about +5.6v on the supply and about -3.3 on the return,
which I'm assuming is normal (?)
Anyone know where I can obtain anything resembling a schematic? Other technical
information (I have a PDF of the technical manual, however it's mostly "system
information" from an operational point of view). Any known issues etc.?
Regards,
Dave

The earliest devices were full height 10MB 8" SCSI drives that had optional slave

Front panels for modern day computers/microprocessors are somewhat
problematic.
The cache(s) maintained internally allow for local instruction execution
without
making references to the external memory buses, and the prefetch
mechanisms internal could
also indicate memory activity even if no instruction or data item were
actually
fetched! Status information is not as directly available, and if it were
it would probably not reflect
status in "real time" that is occurring at the same time of viewing on
the panel.
Nevertheless, memory bus activity could be monitored, and what limited
status information
is available could be produced. The point though is the information
displayed, say on minicomputer panels,
is not readily available now due to higher levels of integration on the
chip itself.
On the note of the CDC 6600 machines, et al., There was a peripheral
processor
which was used to boot the mainframe, and it had many rows of toggle
switches, in groups of 18 or 36
if I remember right, which either contained the boot code or controlled
the boot. The peripheral
processor was a computer in its own right by any standards.
Hope this helps.

Boy, tough crowd...
Repairing a PET is often as simple as reseating a memory chip; worst case is
probably a bad ROM in which case you just replace all the RAM/ROM chips
with one of the modern 64K RAM/ROM adapters and sell the working old ones.
Half the fun of buying something like this is gambling on it being a simple fix.
As Ethan says, if you buy a non-working old computer and don't know (or have
a friend who knows) anything about repairing them, well...
Looks like an up-front description of a non-working system to me; hope he/she
appreciates your advertising the listing here.

Yes, but many sites play music and video via flash controlled webpages
which don't always give you that flexibility.
I am well aware of the ability to download flash video's to my
harddrive. I have about 500 myself (of which about 1% would be
considered
on-topic).
With more and more webpages being filled with flash and javascript
content, it's getting harder to find sites that are actually viewable
on
Amiga's, C64's and other retro computers/games consoles (... trying to
drive it back on topic).

Hi All,
I picked up two interesting machines at the auction this week.
The first is a Monroe Electric Programmable Scientific Calculator model
#1785(circa 1971) alas, it is missing the optional punch card reader
although the machine itself seems to work fine. Also came with some
instructional books!
The second is a Zenith LF-171 portable, which is a re-badged Morrow
Pivot, complete with power supply and the black canvas carrying case. An
8088 (80C88) with an LCD screen!!
All in all, a good take!
Cheers!

You mentioned JPEGs. If you are archiving the scans in JPEG format,
try zooming in on bunches of traces or text on the board. JPEG creates
a lot of artifacts.
It may very well be case that a 600dpi scan using lossless compression
will be much cleaner and usable than a 3200dpi scan using heavy JPEG

Even with 6 mil traces, 600dpi gives you more than 3 pixels per trace.
I've tried a few of my boards using 1200dpi, 8-bit color, and GIF/TIFF,

Does anybody haev a CDC/MPI full height 5.25" floppy drive? No, I am not
looking to buy one, I need some information on how it goes together.
I have one in an HP9826, it's fucntionally the same as a TM100-2A, but
intenrally quite different. The area I am baving prolems understanding is
the head positioner.
The head carriage runs conventionally on a pair of metal rails fixed ot
the base casting. At the rear right of the drive is a stepper motor with
the spindle axis vertical. On that spindle is the metal drum of a taut
band mechanism, there's alos the conventional taut band. That fits over a
pin on the drum. The ends of the band have holes that fit over pins on
the head carriage, the rear p[in being fixed to the carriage, the front
one is spring-loaded to tension the band.
So far, so good.
Mouleded into the head carriage are 2 arms that extend to the right of
the drive, past the taut band assemly. They seem to carry some kind of
damper. And that's the real prolkem
In my drive, the damer had oozed grease all over the chassis. I've
stripped it all down and cleaned it up. What I can't work out is how it
should go back together.
The 'damper' consists of a weight made af a soft metal, probably lead.
And a metal shaft, about 1mm diameter, that runs through a hole in the
middle of this weight, the ends of which locate in the arms I mentioned.
And that's all I have. There's no obvious place to put grease inside the
weight (I've looked down the hole as best I an). If you put grease on the
shaft, it's just going to ooze out again.
Also, what keeps the weight in the right position on the shaft? It's
considerale shorter than the space between the arms. Surely it shouldn't
just flop backwards and forwards?
Another odditiy. When I removed the tauth band, I notixed what appeared
to be a plastic clip on one of the pins. More careful inspection showed
it was an O-ring that had split. OK, I can get replacements. But why put
an O-ring there in the first place? It's not going to keep the band on
the pin, or anything like that.
My thought is that this has been dismantled before, that the O-ring
actually came from the shaft that carries the weight, and that there may
be parts missing (Springs, washers, etc).
Does anyone ahve such a drive and could at least tell me what the damper
appears to consist of (No, I am not asking you to take it to bits, just
indicate if there's anything on that shaft other than the weight, if
there are any ruber seals. etc?

Hi Tony
Since my 7771 1501 dive had problems and I did not find
any Info. I did find a NIB dive. It has the same weight
that seems to be there to stablize the movement of the
head. The weight on the new drive (but old stock) has
no grease on the frame of the drive but was stuck on the
shaft. It does have the thick grease or ?? on the ends of
the weight where the shaft enters and exits. After warming
it a little it started to slide on the shaft. I can slide
it the whole distance. I looked at the old drive and it does
the same. It looks like it dampens some of the quick motions
of the head carriage?? But the grease keeps it from moving
very much.
I would guess it has real thick grease in it ??? So it can
only slide a little on the shaft. It may have some kind of
"o" ring to help seal one end, but I did not take it apart.
If needed, I could take apart the dead one.

Subject: Re: Friden Flexowriter
There seem to be more decwriters around and they can often be had for
cheaper. No paper tape punch/reader there though.
On another topic, I have a "Motorized Tape Punch - Model 2" made by
"Commercial Controls Corporation - Rochester 2, New York" which I
believe became Friden. I have no docs on it whatsoever. The real thing I
need to know is how to interface to it. It seems to be in adequate
physical shape, except for the chad tube. It was made of plastic and has
long since been broken off.
http://rikers.org/gallery/hardware-tapepunch
I'm very interested to hear of any known documentation for this beast.
There's a picture there with the case off, perhaps the Flexowriter punch
is similar inside?
--------------
Can't help you on the interface; almost looks homebrew, considering
it's built on perfboard. Has some previous owner perhaps already built
an interface?
Shouldn't be too hard to figure out though; looks like 8 lines to select
the byte, and there should be another to "clock" it in, i.e., engage
the clutch that drives the perforator. Looks like it could use a little
cleaning & some lube.
I have a unit that uses the same perforator mechanism; the motor runs
constantly and there's a solenoid that trips a clutch to drive the punch
shaft one revolution. There should be some cam switches inside that
cast housing for timing, and 9 interposer solenoids inside the perforator
that free or lock the perforator pins, and the selected ones are then driven
through the tape. (These solenoids actually look like little relays without
contacts).
I doubt that you'd need any parts (these were pretty heavy duty units)
but if you do, I've scrapped a few of these and still have some of the
mechanical parts (no chad tubes though, alas).
mike
Can any of you guys verify one way or the other what that device with the
tubes is that Dave is referring to in my group here?
Feel free to stop on by if you like. :-)

I just added some photos in the Photos section of some really old
computer hardware. These are photos I've taken from my personal
collection.
One is what I've been told is the peripheral I/O register for an
IBM 704 computer (Note the vacuum tubes!).
Another is a core storage (memory) plane from an IBM System/360,
most likely either a model 60 or 65. This particular core plane
was defective, and has been cut out, so it's missing the connection
fingers on the sides of the plane.
The remaining two are a really old computing device. ;-)

A quick question--can you hook a Friden Flexowriter to a modern

interface/converter, but I haven't really found any information about
that kind of thing... if anyone here has experience with one of these,
your input would be greatly appreciated.

Finally saw it in the paper. I notice they talk about how the VAX is
"so old that the University of Washington has an early model (of the
VAX) on display as a museum piece".
Hmm - they probably have an early IBM 5150 and Mac 128K on display as
well. What does that mean for the desktops that the school district has?

I didn't find a lot of information from IBM support on the 6094 - but
I did get some. I have uploaded a old copy of IBM's RS/6000 Graphics
Handbook which describes the IBM 6094 LPFK. The LPFK information is
found in section 4.5.
The good news - in can be attached to a serial port on an RS/6000 or
PC - which means that it shouldn't be difficult to find the protocol
for the critter.
Not a lot of info in the manual - but something is better than
nothing ;-)
You can download a PDF of the manual via anonymous FTP from my

"Black holes are where God is dividing by zero"
Does anyone know how comprehensive the pwer-on Floating
Point Unit test (9) is in the Vaxstation/uVAX 2000 ?
Does it actually verify that the FPU is functional, or
is it just looking to see if some basic indications are
the it is present?
The (9) FPU test is performed at power-on, and also by
>>> TEST 9
I'm trying to determine if the FPU in my VS2000 is actually
working.
Will the console ROM run (normally) without an FPU?
Unfortunately the (hopefully more comprehensive) system tests
don't appear to test the FPU (or perhaps they don't see mine
and therefore won't test it).
Can anyone with a VS/uVAX 2000 tell me if:
>>> TEST 80000106
>>> 9
Actually runs a test (mine just displays the testing header
and halts. Another thing to try which takes longer is to run
>>> TEST 102
And note which tests it runs.
Mine runs:
F (video) - Only if set to VS2000
C (Serial)
B (memory)
7 (Hdc)
6 (TPC)
Noteably missing are:
E (clock)
D (nvram)
A (mmu)
9 (FPU)
8 (Timer)
5 (Interrupt controller)
4 (color FB) - I've got it removed
1 (Ethernet interface) - I've got it removed as well.
All of these pass during power-up and TEST n tests (if
I have them installed).
Problem is, I don't know if the system tests are supposed
to test these or not - I don't have a known good Vax2000
to compare with.
BTW: To run TEST 102 and 80000106 you need to have the system
test "hardware key" installed - this is just a DB-25 connector
on the serial-port with pins 12 and 18 connected together.
Thanks,
Dave

Is there an implementation of Sun nd(4) (Network Disk) server other
than the one in NetBSD, by Matt Fredette?
Long story: Few days ago I fried SCSI controller on Indigo 2, and I'm
not gonna risk the same with my Sun 3/60. Few months ago I got SunOS
3.5 kernel to netboot using modified NetBSD ndbootd(8); it goes as far
as mounting rootfs. Then, just after printing the following line...
using 95 buffers containing 778240 bytes of main memory
... it just retries reading block number 16 over and over. I guess
the ND protocol implementation is wrong somehow. The whole transaction
goes like this; the only thing that changes is the "seq" field.

Curt,
I happened to stumble over a posting that you made on the web about a
year
ago talking about installing some "Metaphor" computers. I am a
former Metaphor
engineer. I have a slide show on my web site that they developed to
celebrate
the death of the company. The software is still around, now called
"Meta5".
I don't want to invest too much in a note that I don't know will ever
be delivered,
but if it does make it to you, let me know, and I can fill you in.

I could be wrong, but there's something fishy going on over at eBay.
First an IMSAI and an Altair 680 being bid up to astronomical prices
and now a less than stellar SOL-20 goes for $7100.00 to someone who's
last couple of purchases were cell phones. This all this activity is
in fact some type of a scam, it is going to seriously hurt legitimate
buyers and sellers.

To Whom It May Concern
I'd like to know the E-Mail-Adress from Bob Maxwell. He wrote an article
in your forum about HP64000-floppys in the year 2004. I need more
Information about these floppys. I have the same problem. I want to get
the information out of 5.1/4"-hp64000-floppys. I'd like to store the files
at a windows95 or windowsXP-computer(or maybe dos). Can you please help
me?
With best regards S?nke Backhaus
(from Germany)
I remember the discussion about bringing classic computers across the
border from Canada to the USA, but, has anyone got any experiences going
the other way? Any issues since many of these systems are USA country of
origin? Especially with big iron, where you'd have a trailer or big truck...

Just fyi, it's not my auction, but there's a pdp-11/34 in two racks, a tape
drive and large hard drives on ebay. Two days left, I figure somebody with
a big truck wants to save it.
I normally wouldn't post about an ebay auction, but this one doesn't
mention pdp-11 in the auction title and seems to have been overlooked.

I stopped selling on ebay before the January 29th announcment and am totally
disgusted with what passes for management. (major rant deleted) Search youtube
for ebay boycott or ebay strike and there are a number of "editorials" there as
well.
I suggested to Sellam that NOW would be a good time to get the Vintage Computer
Marketplace back online, but it hasn't happened yet. Since I haven't kept track,
are there other classic computer related places to buy and sell? A "yes" answer
should be followed by the sites URL :).

Ian,
Do you have the disk controller board for the B80? I developed it back in
1973. If you do could you email me a jpg of it? It has a certain nostalgia
value.
It is also the first ASIC disk controller in the industry, and I'd like to
at least get the photo into the Computer Museum in Sunnyvale.
If there is any thing I can help you with on the machine, just let me know.
I also ran the team that developed the floppy disk drive on the unit.

Q-bus (BA 23, BA123 & (with mods to the mounting hardware) BA213) SCSI
controllers.
What works (in particular with disks + MSCP + VMS), how well and what's
still about ?
What I know is:
CMD CDQ-220/TM supports disks and tapes, and works with RZ2x disks /
MSCP / VMS
DEC KZQSA-AA (aka M5976-AA) is the BA23 Q-bus SCSI controller
CMD CDQ-223/TM is a 220 with EMC shielding for a BA213 box
What I'm curious to know is:
- What boards were made and which are commonly available
e.g. DEC KZQSA, CMD CDQ-220, Dilog SQ706 ?, Emulex UC02 ?, Andromeda
SCDC-11 ?, ...
- The relative (to SCSI 1) performance of each of the boards
- Which boards are "dogs" : gotchas, tape only, unreliability /
electronics failures
And, some specific queries are:
- What is the difference between a CDQ-220/xxx and a CDQ-220A/xxx ?
- What is the functionality of a CDQ-243 (quad board, BA213 cab kit, 2
SCSI connectors) wrt a CDQ-220 / 223 ?

Subject: a bad day for vaxen
well I've had a real bad day.
My vax systems have been in storage for about a year, good storage, not
too much heat or cold or humidity but, I can't get any of them to
function the way I think they should.
4 vaxen (vaxstation 3100 m76, of which 2 are spx), an alpha (dec 3000
model 310), and a vxt2000. I must be doing something wrong.I'm having a
very bad day.
and my vs 3100 model 30 seems to have vanished :(
i tried with a null modem cable and with straight through, with 3
different dec connect cables, and 3 different
(1 9pin, 1 25pin female, 1 25pin male) connectors, and can't get
anything on console.
with switch S3 up or down made no difference. and i'm not sure I'm
reading the LED status lights correctly.
i'm tired. :)
I'm digging out a monitor so I can connect the video directly, with a
keyboard and mouse, but that's always fun.
anyone in or around toronto with a working setup I could pop by one day
and hook up and see what's going on?
I'll double-check that after I try the video.
none of the docs I've found specify if it's supposed to be null-modem or
straight through.
and I think I got it right by using the port with the little printer
symbol on it as console.
the alpha I have has 25 pin female, and the vxt has 25 pin male, and the
vaxstations have what seems to be RJ12, can't they make these things
standard?

In my humble opinion, what's really needed is a quick and reliable
non-contact method of recovering floppy data. Perhaps one of the
more modern head technologies, such as GMR might be suitable for a
head that doesn't contact the media. Or maybe we need to revive the
"magnasee and laser" method.
Increasingly, I'm seeing 5.25" diskettes with media flaking. There's
no way that I'm going to stick one of those into a standard floppy
drive, even after baking.
It might be that we're starting to approach the "use by" date with
some brands and need to resort to other approaches.

Yes, it's useful to have a KZQSA if you want to boot from a SCSI CD-ROM
and install VMS.
I believe a KA655 (3800 / 3900) won't boot from a KZQSA, but a KA660
(4000/200) will.
Well yes, its for the CD ROM holding the VMS distribution. However it
does at least recognize a DEC RZ series disk. I worked for DEC for a
long time and 'unsupported' means field service did not have funding for
what could be non-Dec (SCSI) devices on the controller because DSSI was
DEC's own SCSI variant.
It does not mean 'this does not work' In fact DEC engineers routinely
evaluated third party SCSI drives on it.

Huh?
The KZQSA was the controller that generally was used to attach a SCSI
CDROM to a later model QBUS MicroVAX or VAX 4000. I seem to remember
posts on here indicating that you could also use it for a single SCSI
disk, and it mostly worked, as long as it didn't have >1 device on it.
Other than that, IIRC, it's VMS-only.

well I've had a real bad day.
My vax systems have been in storage for about a year, good storage, not too much heat or cold or humidity
but, I can't get any of them to function the way I think they should.
4 vaxen (vaxstation 3100 m76, of which 2 are spx), an alpha (dec 3000 model 310), and a vxt2000. I must be doing something wrong.I'm having a very bad day.
and my vs 3100 model 30 seems to have vanished :(
i tried with a null modem cable and with straight through, with 3 different dec connect cables, and 3 different
(1 9pin, 1 25pin female, 1 25pin male) connectors, and can't get anything on console.
with switch S3 up or down made no difference. and i'm not sure I'm reading the LED status lights correctly.
i'm tired. :)
I'm digging out a monitor so I can connect the video directly, with a keyboard and mouse, but that's always fun.
anyone in or around toronto with a working setup I could pop by one day and hook up and see what's going on?
I'll double-check that after I try the video.
none of the docs I've found specify if it's supposed to be null-modem or straight through.
and I think I got it right by using the port with the little printer symbol on it as console.
the alpha I have has 25 pin female, and the vxt has 25 pin male, and the vaxstations have what seems to be RJ12, can't they make these things standard?
_________________________________________________________________
In my humble opinion, what's really needed is a quick and reliable
non-contact method of recovering floppy data. Perhaps one of the
more modern head technologies, such as GMR might be suitable for a
head that doesn't contact the media. Or maybe we need to revive the
"magnasee and laser" method.
Increasingly, I'm seeing 5.25" diskettes with media flaking. There's
no way that I'm going to stick one of those into a standard floppy
drive, even after baking.
It might be that we're starting to approach the "use by" date with
some brands and need to resort to other approaches.

Hi
I have nearly all I need to do a Vax cluster. Namely a VAX 4000
model 200 , a 300 and a 500.
I'm a few bits short for the 300.:
1. The Console Bulkhead Assembly. (70-27400-01) Its like
a door to the Processor / Memory mounting area.
2. The top part of the two part front door on the BA440
3 One or more RF series drives and the Bezel Assembly
(70-27049-02)
4. Filler strips to go over empty Qbus slots.
5. A KZQSA SCSI controller.
I can get this stuff from theUS but the price is a rip-off and the
shipping horrendous.
If anybody has or knows where to get any of these items in the UK or
Europe I would be pleased to hear from them.

We've had this thread before, but don't forget about stuff like
Stabilant 22. I had endless problems with sockets in AIM65s
(similar to the cheap sockets in a PET) installed in a plant full
of oil and other contaminants in the air; finally pulled them all
out, cleaned and treated the sockets & chips with Stab 22,
and no more problems.
Also did my PETs at that time and never had a problem with
IC sockets in them either; still running fine today.

It was possible to do this. Univac metal tape reels actually had a spool of
mylar tape to isolate the metal tape from the heads, for example.
There would be a lot of loss in the transducer, though, which you may be
able to compensate for by using a magnetorestrictive instead of inductive head.
I haven't pulled apart an Iomega bernolli drive to see if you could fly a
5" floppy over the plate and use the head in it for recovery.
> So I'm wondering if temperature has any affect on media readability.
yes.
You walk a very dangerous line with condensation reading cold media, though.
It has been my experience that mag tapes shed more if they are warm, so after
baking, I let them return to room temperature in the tape reading room, which
is dehumidified to as low as the dehumidifier will go (< 35%)

It's entirely possible that it would work correctly.
Covention has always been that PMI memory immediately precedes
the CPU, and NON-PMI memory immediately follows the CPU.
I've always just assumed that there was a reason for it,
and never really questioned it, since I had no need to.
I'm surprised anyone would bother with an RLV11 in a BA23,
since the RLV12 was readily available at the time, and supports 22-bit.
Much less space, power, and heat.
Although sometimes you just have to work with what is at-hand. ;-)

Periodically I thow this request out to see if there are new cctalkers
watching. I have a long term goal of rebuilding both my 5363 and 5364
systems. But I've never managed to source a copy of the OS media. I've
long had a copy of the media for 5360/5362, but that's not binary
compatible and is distributed on 8" media anyway. So one more time... does
anyone have System 36 SSP on 5.25" media I can beg, borrow, or buy? Can
anyone help?

If your're tight on open slots, the 3rd slot is a good spot for a quad
board,
since the CD slot is otherwise unuseable in your current configuration.

I was going through some old code and discovered that I wrote a DOS
driver to handle Honeywell-Bull DPS9000 GCOS floppies. I don't
recall the exact circumstances, only that we equipped the customer
with a Compaticard and a modified dual drive (5.25" and 3.5") box,
although one isn't required for operation.
Does anyone collect these old systems? Would you be interested in a

After seeing the discussion on placement of RLV12 in Q-bus, I got the impression
that some people think that any quad card can be placed in both Q/Q and Q/CD
slots without worry.
That's incorrect. Some quad cards can be placed in either, but there are jumpers
that needs to be set accordingly for the system to work.
Just thought I'd point it out. It's not as easy as ABC.
Oh, and Unibus is really simple as well, despite what people say. :-)

Perhaps someone could clarify, the manuals are less than explicit on
this. What kind of slot can the RLV12 be placed in? Does it need a
Q22/Q22, Q22/CD, does it not matter, or are there jumpers to
accommodate either?
Before I fry something I'd like to make sure I've got this right.

Way back, wasn't there talk of some kind of "rescue map" showing which
classiccmpers lived where (roughly) and thus providing a clue as to who might
be able to help* with rescues?
* I'm thinking pickups, extra people-power, or just "get stuff a little nearer
to me"...
Maybe it's one of those Google Maps type applications, along with some contact
info and the type of hauling ability (micro/mini/mainframe) potentially available?
(I'm trying to work out the best way of getting a mini-sized system from the
middle of CO to the middle of MN at the moment - or at least get it a little

Two additional points - based on questions I received regarding the
MINDSET systems:
1. If you are not local, Weirdstuff will ship. If you win the lot,
just tell the person who calls you that you want the lot shipped.
2. I said "Two brand new MINDSET systems" - I should have said
they "look brand new". I have no idea if they are really brand new
or are just in excellent condition...

As you've probably read in a previous reply, it doesn't really matter
what type of slot it goes into, as long as you're not interrupting
the path of a 2-board set. i.e., don't try to put it in between
the boards of an RLV11.
Now that I think about it, I guess it's a little moot, since
you're in an 9278-A backplane, which only has 3 CD slots.
The only way you could even use a 2-board CD-interconnect
(such as the RLV11) is with a single-board CPU with on-board
memory, such as an 11/53 or 11/93. Otherwise, your first
two CD slots would already be full. ;-)
One thing that has always made me a little paranoid
about the RLV12 is the heatsink for the TO-5 transistor.
It's very tall, and it sits VERY close to the boards above it.
Be careful if you install the RLV12 underneath any dual boards.
A little bit of warpage, and. . .

Hi,
What can I say...
Thank you so much for sending the BIN files for the EPROM's, that was most kind of you.
If you no longer have the 1631, then I take it that you do not need the grabbers. If you still require them, just send your address and I will post them off to you.
I was given the HP1631D by a kind gentleman on the vintage radio forum. He had played around with it and re-written some of the EPROM's (bad move).
I will program them up tonight and see what happens....
Thank you so much once again, if I can help you in any way in the future just let me know...
Daniel.
Hi All,
There is a big lot of Motorola 88000 boards for sale at eBay 300198415832.
Unfortunatelly it is an USA only sale.
Normally these go dirt cheap to resellers for spares with huge price tags (easily starting higher than 1k$).
Is there anybody interested to share this deal and ship my part to Europe/Finland.
I will pay pmy art and the shipping of course.
I'm really interested in 4 processor modules, which seem quite rare (and I have none).

Don't forget that, after an auction closes, there is a small window of
time
where the auction isn't searchable.
I've had this happen many times; I went to find an auction;
realized it must have closed, and then tried to search it in
completed items, but could not locate it.
Going back to internet-exploiter "history", I was able to go
directly to the auction that I was looking for. . .

Yes and no. yes you can use ram (or flash) as "disk" but the bubble
system was addressed and generally run like a FDC with a command-status
register and a data register. To have ram look like that you's need
some controller and/or hardware. IT would also impact software that
was designed to talk to it.
Bubble was not RAM is was block accessable storage.
>In the same vein, how about MRAM as a core memory substitute?
Yes, it's been done. I had an 8E with a ram card, It stayed with
the machine when I passed to to someone else. Also PDP-11s (early)
could ahve ram or core and I ahve a 16k core stack for a Qbus LSI-11.

Second to my Personal Iris 4D/20, the Apricot Xen has to be one of the
most memorable systems I ever saw when I grew up.
I can still vividly remember when my dad had them in his office and
whenever I was there I would either bolt for the 4D/20 (They cared so
much for the system that they let a five year-old play with it but on
the other hand they did give it to me two years ago for nothing. :D) or
the Xen that was right next to it.
If memory recalls it had the trackball mouse as well as the 3 1/4"
floppy drive and a hard drive and best of all it had that keyboard with
the LCD panel and the programmable buttons.
Sad to say they vanished all one day and since then (a little over ten
years) I have been trying to find another Xen for myself. It seems it is
not an easy task. Not only were Apricot systems not really liked here in
North America but whenever I do manage to find a Xen it is ALWAYS
missing either the keyboard or the mouse...or both and don't get me
started with the monitor or the power supply. I can never seen to find one.
Now that I own a logitech G15 keyboard and have it on my high-spec
system I am now even more determined to find a Xen so I can mess around
with its LCD panel.
Does anyone have one with at least the keyboard and trackball mouse?
Since words really can't describe this system, here's info on the system.
