Now, hold on there, slim . . .
The GDM1950 that I had for a couple of years required negative-going sync.
The PC may not be generating negative-going sync, but you can bet it will
generate negative-going composite blanking! What's more, the GDM1950 I had
was complete with a switch which enable sync-on-green decoding, and it's
likely this one has it too. That provides an alternative to figuring out
how to switch the polarity of the sync the card puts out. I've never been
particularly good at that sort of thing, hence once built a little adapter
with XOR buffers, each of which could serve either as a buffer or as an
inverter, depending on how its "other" input was jumpered.
I'm also not convinced that the notion of "seeing something" as opposed to a
total lack of sync give much encouragement. If the polarity is wrong, for
example, it's likely even a monitor being driven at the right frequencies
will fail to sync. If only one of the sync signals is at the wrong
polarity, it might seem to sync, or not, and if only the vertical is right,
or only the horizontal is right, who knows what will be seen. The first
step, IMHO, is to examine and measure the signals. Since they're available
separately, It should be easy to count them.

The Flex02 was originally sold by AED, I think Chrislin bought out that

The book says "The FLEX is constructed to interface a 50-pin flat cable
with pinouts of the Shugart 800 Structure. Any drive with similar structure
may be interfaced." This means that all the smarts are on the board itself.
While I have the FLEX book in front of me right now, it refers to "Logic
Diagrams" that I don't have in front of me for jumper settings. I'll try
to dig these up for you. But if you just cable the Flex up to two
SA-800 style drives and put the controller in a Q-bus backplane, you ought
to see the heads load and seek to track 0, and then unload.

Anyone have a list of CD-ROM's that will work with VMS? ie, that are
physically settable to 512 or
accept the appropriate mode command? I have seen a few mentioned here and
there, but I suspect
there is a list somewhere.

>> The GDM1950 that I had for a couple of years required negative-going sync.
I'm sure it was one of these that I had hooked up to a PC at one point -
I also had a 16" workstation monitor which was sync-on-green and for
which I built an external module to combine the sync outputs from the
PC. There used to be quite a few websites out there explaining how to do
all this - I believe there may even be a Linux HOWTO document on the
subject somewhere (I don't think I have any documentation on the subject
these days though).
I assume if you're using a PC running some form of windows you can
rework the graphics drivers somehow to drive the monitor properly?? It
was easy under Linux, and these sorts of monitors were best for building
X terminals based around old PC hardware running Linux (not something
I've done for a while though...)

The RQDX series only need a breakout board because they cram the signals
for hard drives and floppies together. This Flex02 most likely goes
straight to standard drives -- a quick check is to see if all the
odd-numbered pins (ie, everything on one row of the connector) is grounded.
If so, chances are it's a Shugart interface.
Don't be put off by the lack of a floppy controller chip. No ordinary FDC
can handle the mixture of FM and MFM usd by an RX02.

Hello Everyone,
I just got (from Chrislin no less!) a Chrislin Q-bus based floppy
controller called a "Flex02". This was from a clean up they did and they
have _no_ documents. Apparently there was a large fire that destroyed most
of their archives.
My contact at Chrislin said it "emulates and RX02 and the indicated jumper
specifies 'boot rom' enabled or not enabled." Which is fine except what he
didn't know is whether or not the 50 pin connector expected to go straight
to a pair of 8" floppies or to a breakout board ala the RQDXn series. So...
if anyone has docs on this board and could tell me what I need to hook it
up I'd be grateful. This is what is on the board:
Dual wide Q-bus, w/Z80A on board and some ROMs for the Z80. ROM labels are:
390028 01 P
390029 01 R
890012 01 M
890013 01 K
Edge of the board says (c) 1980 "Flex 02" Rev 5
Back (solder side) says ICIM94V1
It has a 50pin edge plug and ahead of that plug is an NEC 8255 (this is a
parallel port so it suggests to me at least that there might be some "off
board" intelligence required. No sign of a floppy controller chip.

I have slowed down my collecting a bit because of space (warehouse and 4
storage units full plus what's in the house), so I'm looking for manuals and
specific machines to round out certain brands/models. Today I got 30+ books
for 10 cent each and one was a CP/M-86 operating system System Guide by
digital research dated April 15, 1983 Rev. 00 in very good shape. I also
got a ton of old software include on 5 1/4 diskettes for free. A lot of
drivers and setup disk for older machines. Saturday I did pickup a Laser
Computer XT that looks just like a Laser 128 must use the same cases. I
also got two external floppies with it. Keep computing.
I use really cheap video cards and they won't do this job! The older ones
which allowed you to specify whether they interlaced or not with, say, a
switch, would do it, however.
It takes a really fast DAC to shovel out the bits fast enough to allow the
production of 1280 dots at 64KHz! Most VGA makers have settled on a maximal
rate of 65 MHz, which means they have to interlace the 1280-long lines. If
you shop for older boards, you may find some capable of doing this task, but
they may fall short of your wishes for wild and crazy game graphics, as they
haven't the features newer cards offer.
IF you find a suitable card, let me know, plz.

Dick, could you elaborate on this a bit. I realize it is a bit OT but I
have
a SuperMac rebadged 19" GDM1950 that I picked up from the curb. It has 5 BNC
connectors and displayed a dark screen when I powered it up bare, but I was
encouraged because there was static on the screen. When I connected it with
the
5 BNC connectors to the adaptor I use on my NEC multi-sync 4Ds and turned it
on
without a computer powered up, for one glorius moment it displayed an azure
screen which then turned "IBM-blue" and then either to jaggies or dark(can't
recall which). Since then it only displays jaggies. I hesitate getting a
fixed-freq card for it since they are quite expensive and I'm not sure it
works. As well, I use the NEC as an all purpose display with DOS, Mac, and
PS2s
on a ABCD switchblock so it would only be a secondary unit.
The big screen is enticing however and if I could use it without having to
lay
out too much, since there's no guarantee that it is actually functioning, it
might be impossible to resist. I'm semi-retired, so money is an issue.
What is the "application connector composite blanking signal" and where
would
I find it. Would the V-sync and H-sync BNCs be ignored ?
Also do you have the name of this company that has these cards ?
I've also seen unverified info that some ATI cards work with this monitor.
Obviously you would need an adaptor but have you heard of this ? I have an
MCA ATI Mach-32 card in one of my PS2 beasts but have been reluctant to try
it
with the GMD1950 because of fear of the "magic smoke" escaping . Both my
Power
Mac 7100/66AV and PS2 80 have on-board video and secondary monitor abilities
I
believe.

OK. Found and installed a 74LS32 at U30.
There are all kinds of jumper pins (with
wire wrap wires connecting various pins)
and DIP switches on this thing.
I started to try to describe all the pins
and switches on this board... gave up when
I got to 200 lines. There are 11 blocks of
jumpers and two sets of DIP switches. Could
some kind soul email me the config info (at
least for the serial port) on this thing?
Thanks,
Bill Sudbrink
have you emailed Todd Fisher of www.imsai.net fame? I asked him for
connector pinouts for the PIO4 and PIO6 boards and he did, after some time
searching for and preparing the documents, post them on his web site. I've
already checked and the MIO is not supported yet. Perhaps a little jarring
>from you would motivate him.
He's probably busy, though, as he was planning to release his new computer
in the old box, or whatever he was planning . . . by mid-summer (that's
now!)

its worth 2.98 without the a/c adaptor which is what i paid for one.
I meant to post this Tuesday, but things got busy.
My IMSAI is up with the front panel, CPU and
memory card. I can now reliably do all front
panel operations and can toggle in and run short
programs on either the 8K SRAM or 64K DRAM card
(only one in the box at a time). For those keeping
score:
Replaced all chips on the front panel. All are
now socketed.
Replaced two switches on the front panel.
Routed several traces around burned or otherwise
damaged spots on the front panel.
And... (this is the kicker)
Re-patched the MWRITE circuit. The original (and
incorrect) patch brought the SOUT signal to U25
pin 5. What was actually required at U25 pin 5
was NOT-SOUT.
So next, I suppose, is to get the MIO working
(at least the serial port) so I can get a terminal
on this baby. If anybody has MIO REV.2 schematics,
it might make my life easier. To begin with, all the
chips on this card are socketed. It is a very neatly
and carefully done soldering job. The following chips
are missing: U8, U11, U30 and U34. I can see the
silkscreens for U30 (74LS32) and U34 (8T20), but the
sockets hide the silkscreens for U8 and U11. Does the
absence of these chips simply indicate that one of the
functions of this board is disabled?
Thanks,
Bill Sudbrink

Of course? I don't understand the "of course". I see no fundamental reason why
a larger format will give you a greater resolution _per mm_. In fact, I would
think that the wider viewing angle for the same focal length would mean that you
might get less resolution.
The big advantage as I see it of larger formats is that for the same resolution
per mm you get much more detail in the frame!
I use medium format - I got a Yashica TLR (Rollei clone) for 6 pounds at a
charity auction a few years ago, and it got me hooked on it. Recently I damaged
my Yashica, so I've just bought a Hasselblad (a good set of accessories is
looking rather pricey, though). I'd love to find an 16384*16384 or similar
digital back at an affordable price! Heck, if I saw a 4096 * 4096 digital back
for my 'Blad below 500 pounds I'd probably buy it, even though that's only 36
lines per mm!

I think there are two independent viewpoints here. If you are taking pictures
for display on people's computer monitors (e.g. on web sites) you don't need
more than a few lines per mm, since the monitor itself will probably only
display 3 or 4 pixels per mm (say 2 lines). A 640 * 480 pixel picture is the
largest that will display on many people's screens. For this purpose a digital
camera of say 1280 * 1024 is probably perfectly adequate.
If you're taking pictures to blow up to a foot or two across and print on high
quality paper, then most digital cameras are quite inadequate, and a large or
medium format or really good 35mm film camera is required.

Tony, when you talk about 640 pixels across a 4 inch print being only 6 pixels /
3 lines per mm, you've just stopped looking at film resolution and started
looking at print resolution. Don't forget that the standard 35mm negative is
generally considered blowable up to as much as 12*8 inches, so 100 lines per mm
at the film becomes 12 lines per mm at the print; 3 lines per mm at the print
corresponds to 25 per mm at the film. So it is poor resolution, but not the
"nonexistent" resolution you were talking about.
On the subject of lines per mm, what is the resolution of a typical ccd per mm
_at the surface of the chip_?
Philip.
PS why do people so often talk about blowing 35mm up to 10*8 or 12*10 as the
limit? Is it simply standard paper sizes? It's certainly not the aspect ratio
of the negative.
A repost for those who didn't see it the first time. I'm only posting it

I have a few bits and pieces here which I want rid of ASAP, I did have someone
interested in them some 8 months ago (noone on this list I hasten to add) but
since he let me down I'm posting them here.
List follows:
Wang keyboard.
Olivetti wide carriage daisywheel printer (from S100 based WP system)
Star NB-15 wide carriage 24-pin printer
Princeton Graphics EGA monitor (x2)
Nixdorf VDU
Televideo 950 VDU (x2)
Zenith Z89 VDU
The latter items would really only be good for spares, e.g. the Star Printer
needs a new printhead, the Z89 is missing the "video" board, the TV-950s won't
communicate with their keyboards, but it's all available for the
cost of coming to get it.
I'd rather not dump this stuff in a skip but that's where it's all headed and
soon if someone doesn't take it away. I'm located in Birmingham, email me
directly if interested.

Having recently gotten rid of my Sun 3 series workstations I'm left with the
monitor, it's a 20" RGB unit (made by Sony I think) and was previously attached
to my 3/60.
Anyone in the UK interested in this? I'd be interested in swapping it for
something I can use, like a colour VGA monitor (PLEASE!!!) or something
obsolete.... :-)
I'm located in Birmingham and due to the size of the thing I'm NOT shipping it,
so it's come and collect only.

I have little experience with Polaroid since the '60's when I occasonally
used a Polaroid back for my 4x5 (9x12 cm) Linhof. Since then I've only used
Polaroid for 'scope pictures.
However, what I do recall is that while they're OK for use as full-scale
snapshots, the film is too grainy for enlargement. I learned about this
when I used the negative film from Polaroid. I've concluded that the
quality of the photos from this technology is not as high as what's wanted
by users of digital photography in general, i.e. I doubt it's up to the
quality of the 640x480 resolution of the Sony cameras.
My interest in digital photography has been stimulated by the need to
integrate photographs into technical documents and correspondence. There's
plenty of software for rendering the color photos as what they are, up to
"glossy-paper-magazine" e.g. Time or Spiegel but once you start to enlarge
the image, the lack of resolution becomes a major factor. I've considered
other image processing approaches, e.g. scan-rate conversion software which
reduces a raster image to Fourier series in both directions, thereby
allowing you to "fit" the image to whatever resolution you like, though it
requires post-processing to straighten and sharpen edges, etc.
What really puzzles me is whether it can process and render a photo as black
and white line-art. Anyone have
experience with this?

Is there a good reference around that explains the details of setting up
SMD devices, specifically Fujitsu Eagles? I know nothing about them.
And this Sun3/280 here has two Eagles. One of them has a bunch of
connectors on the back (a db25+db50? for command in, the same for command
out, and then a seperate db25 'data'). The other drive (that I thought
was identical) lacks all those connectors, but has a rainbow-colored
ribbon cable coming out from underneith the back plate that splits into
two parts, one that larger db50? connector and another db25 (with a box
that is plainly labelled rs232 gender changer). This has all vastly
confused me.
I was able to boot SunOS 4.2 off the Eagle with the connectors partially.
However, the second eagle is listed in the fstab and it tries to check
them, failing miserably, and dumping me to a prompt. However, aparently
there's something else going extremely wrong as well since I can't type
anything at that # prompt (using a type 4 keyboard with a homemade adapter
to the Sun3 connector, the prom (v2.6 i think) detects it just fine as a
type 4 keyboard -- does SunOS 4.2 not support type 4 keyboards?) I know
its still running however because its still puts out an 'ie0: carrier
lost' message every few moments. Btw, I'm using a 501-1116(?) video card
in slot three, and it seems to work just fine -- I don't have a monitor
capable of using the onboard mono video.
Lets see, what else can I complain about. Oh, how much power do those
Eagles use? I've been plugging them directly into the wall (bypassing the
/280 rack's distribution panel, which uses a big (30amp?) plug that I
defintly don't have anything to plug into). Do any special considerations
need to be taken here?
mid
PS: Anyone know where to get boot images for an NCD 17in xterm? Or know
how to troubleshoot an HP Apollo 425t that won't come up to a boot monitor
(even serial)? Maybe a reference to what all those status lights mean
would help.

Well, I'm in Denver. This thing was given to me back in the CP/M days, as I
was using a CDC Lark drive on one of my CP/M systems.
It was in the possession of an employee of one of my clients about four or
five years after he'd collected it in place of a couple of days' wages when
they went under. I got quite a bit of office furniture and some almost
useful computer boards. They still owed me for a couple of thousand memory
IC's I'd previously obtained on a similar basis from yet another client who
hired competent help a bit too late.

Since SMD's have popped up again, I'm reminded of a rather large item taking up space and doing little else of use hereabouts. This thing is an SMD tester, obviously packagaged for the travelling service person, i.e. in a fairly typical sized suitcase, larger than my TEK TM535 suitcase, and really quite typical of the size of a man's suitcase. It weighs about what a typical man's 5-day case weighs, so how you get it is up to you. It's here, and it's yours if you're the first one to collect it. I saw it in the shed the other day, and haven't looked at it since, however, so I can't vouch for its functionalitiy.

I have been shifting *heavy* things for the last two weekends...
now stuff's Gotta Go.
FREE!! FREE!!! FREEE!!!
Anyone want a nice CDC 9766 Storage Module Drive with four full
and one half packs, and spares? It weighs >650 pounds and takes
220V, but it's free, and it's going to get delivered to you, a
freight company, or the Champs de Junque the next time I have to
move it. Right now its in covered outdoor storage (in my carport). I
can deliver it in SoCal if you can get it off my truck at your
place.
LAST CALL!!! on the Wang VS7110 system, including four Fuji 8"
drives and two Printronix band printers.. was taken out of service
and stored, I saved it from the Dumpster/Skip/Tip/Basura... but it's
looking more and more like I'm going to have to dismantle it and
heave the better part of it. I have made enquiries on the few
Wang-specific sites I have been pointed toward, but nothing so far.
It is probably 1500 pounds in three large cabinets. Delivery will be
a Factor to be considered. I have most of the docs, and more than
likely >25 terminals for it, but they are in deep storage in the
Company warehouse.. if you want the Wang, I'll dig out the
terminals.
IBM 3714 terminal control unit.. free free free.. come and get it,
it's light enough to fit in a big car or small truck. Have set-up
diskettes but no doc. Soon to be Trash....
Somebody stop me before I SCRAP again........

Well, as long as I'm replying to classiccmp e-mail, I may as well
get my two cents in on this thread.
It sounds to me like Tony has higher expectations than most of us.
Although I'd love to find a web site with _all_ the technical
details for a favorite system, it doesn't even happen in my daydreams.
To few people are in a position to put in the amount of effort,
time, and money to create that kind of thing. That may be changing
as disk space gets cheaper, higher resolution cameras and scanners
get cheaper, and our minutes of spare time add up to become whole
hours.
In the meantime, I still get some nostalgic jollies from seeing
low-res snaps of old machinery. That is not totally useless, even
if it is not yet enough to help me repair one. Heck, it could even
be useful in a technical way, as an aid to the identification of
those machines for people who have never seen one.
Then too, I've seen web sites in which all text was encoded as
images, with no "alt" tags. So there are certainly useless images
out there, by nearly anyone's standards.

Is this a TZK50 tape drive, or a TZ30 tape drive, or something else?
In any event, assuming a TKZ50 or a TZ30, this is often caused
by the leader coming unhooked from the plastic take-up strip. Sometimes
what you've gotta do is manually unload the tape. Let us know which
tape drive is connected and we'll give you some help.

Hi,
I've got a Burroughs Class 5 adding machine here, which I am almost

I picked up a Sun 3/260 and a 3/280 yesterday. After pulling all the VME
boards from the /280, I found one I didn't recognize....
Board marked:
Clearpoint Research
SNX2RAM/8 Rev A
Serial Num 639
Copyright 1988
Major chips: (lines seperated by /)
N8X401I/ABW7840
CSI 5134/NCR0380477/F830215 F8816
CSI 5133/NCR0380475/F828347 N8749
Anyone have a clue what this is? The guy I got it from said he was told
it was an FPU. That doesn't make a whole lot of sense to me. It's also
got what appears to be 1mb of SRAM on it. The low serial number makes me
think its something a bit specialized, but I don't really have any idea
how many Sun3s were sold to compare that with.
thanks

Bill Sudbrink
Sorry, it turned out to be this evening instead of
this morning... Anyway, here are the important
bits to get the 600 (Superboard II) going:
J2 (to the left rear as you are looking down on the
board with the keyboard toward you):
Pin 7: casette out (to tape player mic in)
Pin 8: casette ground for both casette in and out
Pin 9: casette out (to tape player AUX in) (same as pin 7
except pin 7 has an additional 10K resistor in series)
Pin 10: casette in (to tape player headphone out)
Pin 11: video ground
Pin 12: video signal
(Other J2 pins are either no connect or are used for
serial port implementations. These are not populated
at the factory and don't look like they are populated
on your 600)
J3 (to the right of J2) gives TTL level access straight to the
USART and is not normally used.
J4 (to the left of the keyboard) gives you access to the square
wave generator circuit (not factory populated) and to part of the
keyboard logic (I guess to attach a non-analog joystick or
a numeric keypad).
J1 (the 40 pin DIP socket just above the keyboard to the right)
provides access to all address and data lines and some 6502
signals)
The board wants +5 volts usually attached at the back right
side to one of the pads labeled with a +.
The ROM code wants all caps as input, so make sure your
SHIFT LOCK key is down. If everything is working, when you
power up, you will get a screen of garbage. Don't panic.
Press the BREAK key. The screen should clear and you should
get a prompt like:
D/C/W/M?
Press C (again, case matters). Just press return if it asks for
screen width or memory size. You should then be in the BASIC
in ROM.
That should get you started,
Bill

Wow! I worked with John Goltz around 1984-1986. We both worked at that
company I've mentioned here several times, Software Results Corp, the one
that made the COMBOARD and the one that sponsored "CPU Wars" (with the back-
cover ad). By the mid-eighties, he had moved from Ohio to Arizona, where
he still is. It's been a few years since I've talked to him.
I heard a great story about his days at CI$... He was looking over the
terminal driver and spotted ONE line of assembler with no comment. He
just _had_ to figure out why it was bare. It was, IIRC, a 36-bit immediate
compare against a constant that happened to be a packed ASCII string of all
"$" characters, with a branch. He determined that *that* compare and *that*
branch allowed a person to type ANY CompuServe user id code and use a
password of all dollar signs and log in as them! Talk about a wide-open-
back door. It was patched a short time later. I use the story as an example
of how powerful a single assembler instruction can be on a decent processor.
> By 1978 we had two computer centers - the one in Arlington full of KI's,

In 1988, I worked next door to the Dublin data center, parking my car about
20 yards from the monster dish they had on the west side of the building.
With all that, I am still 10-less. :-(

P.S. - In this CI$ thread, someone mentioned how expensive the service used
to be. I got my first modem in 1982 - a VIC-modem for the C-64. CompuServe
was $6.00 per hour *off peak* at 300 baud. I don't remember what it was at
1200 baud, I couldn't afford the modem, let alone the online charges. I
seem to recall that on-peak 300 baud was $22, but that might be bit rot.
P.P.S - in 1986 when I got my TTY with built-in data-set and touch-tone
pad (the one that is no longer installed in the unit), I wanted to test
the modem. I plugged it into the phone line and dialed up CompuServe.
It worked at 110 baud! I didn't stay on long at less than half the normal
bandwidth. but I did get on.

wasn't worth trying to fix the 'second half' of it. From what I remember,
the camera had standard RCA connections, so it would be good for a
video-capture camera.
Talking about video capture.... and video standards... On my video card,
there's three plugs: VGA, composite, and S-Video. What is S-video? my
video card didn't have a manual with it, so....

I'm not convinced that it is a Datamaster. The screen is too small, and the
screen bezel the wrong shape; the trim is the wrong colour (ok, maybe it's a BW
photo, but the trim on a System/23 isn't usually that dark that I know of).
And, as I said, System/23 is 5322, not 5051 or any of the other model numbers
we've been seeing here :-)

Well, the model number at the first URL (Thanks Reuben) is 5120 - so which is
correct?
I agree that the "5051" looks very like a "5120" - far more than it looks like a
Datamaster.
So perhaps it is a 5110 derivative...
