So I was digging around looking for one of these (an 8000-line
CRT-based film recorder, basically it's used to print digital photos
to photographic film), and I managed to find one being liquidated.
Unfortunately they will not ship, and I'm in Philadelphia, which is
rather far from Richmond. So if anyone wants to pick this up, feel
free - $20 or so is quite a deal, as this model can fetch $350 or so
on eBay.
http://www.govdeals.com/index.cfm?fa=Main.Item&itemid=18024&acctid=226
It hasn't sold the first time they listed it (at $35) so I don't
expect it to go for much. I'm willing to pay the cost, and for
shipping and the trouble, but if you're doing photographic stuff, by
all means use it. I just don't want to see it get dumped or recycled,
like most unsold surplus items end up.
Thanks!

Subject: Wanted: Original Kaypro 16 floppies
I've been looking for an original floppy disk set for my Kaypro 16 (not 16/2

with? Or, worst case, anyone have a set they could copy/image for me?
Thanks!

Thanks Jay,
Using this, I was able to get the power supply going. All voltages
check out OK, so after some careful examination I've plugged in the
CPU board. The expected output on the console port is the "O" from
"OK"; the K isn't printed because there's no memory.
Powered it on, and after some twiddling with the console cable pinout
(weird one) yes, there's the "O".
Installed the memory board, powered it on again, and alas, still "O"
rather than "OK". The Field Engineer's Reference says that that means
a memory failure.
Of course, the memory board could be faulty, but it could also be a
matter of incorrect jumper settings on the memory board. I haven't
been able to find a description of these yet.
The board says "DGC BBU MEMORY", and contains 8 x 16 AM9016DPC ic's
(4116 equivalent). That makes it 128 16-bit kilowords of memory (no
parity or ECC, although there are 5 empty spots per row).
There are 6 jumper positions labeled 16,17,18,19,0 and 1; each can
have a jumper in the 0 or in the 1 position. My board has a jumper in
the "0" position for jumpers 16, 17 and 18. No jumpers in the other
three positions:
o o o o o o
1
o o o o o o
0 | | |
o o o o o o
16 17 18 19 0 1
Is anyone familiar with these?

I have an old project laying around that I just spent another two hours
on ..
It is an 1993 external parallel port attached CD-ROM. A company called
"Storage Devices Inc" made it, and IBM resold it. The model number is
SCD-683. There are some traces of it if you search the web, but not
much interesting. I have the drivers so that is not a problem.
The CD-ROM is a 1x SCSI unit that uses a caddy. There is a parallel to
SCSI bridge board in the enclosure based on the NCR 53C80 chipset, which
was well known back then. The CD-ROM does show up and talk when used on
an XT running PC DOS 3.3; it responds to commands like eject and it lets
me see its error counts using a utility program.
The problem is that it refuses to read any media that I give it. The
drive is very clean - I removed the top and had a look inside the
mechanism to be certain. It is a caddy loading model so I can't tell for
sure that the head has clear access but everything seems to be operating
freely. I'm using old pressed aluminum discs (OS/2 Warp) which should be
fine in any CD-ROM device. I have tried cleaning the heads with a
special CD that has the magic fibers on it, but nothing is helping. (I
even reached in gently with a Q-tip and isopropyl alcohol, but that did
not change anything.)
I'd like to see this thing run - it has a carry handle on the side!
Unless I come up with another idea to try the only way that is going to
happen is if I swap the drive out. The original drive is an IBM
CDRM00101 and the driver is looking for the ID string. So a drive swap
with a different SCSI drive will probably require patching the device
driver.
So, any ideas on what I can do to clean the head further? (It might just
be hopelessly out of alignment - I don't know the history of the drive.)

Announcing the Retrochallenge 2012 Summer Challenge
As usual the competition is open to all, so come and join us for a legitimized month of playing, hacking and blogging with/about your retrogear.
For those of you new to retrochallenge the philosophy is:
About RetroChallenge
In a nutshell, the RetroChallenge is a loosely disorganised gathering of RetroComputing enthusiasts who collectively do stuff with old computers for a month.
The event is very much open to interpretation... individuals set there own challenges, which can range from programming to multimedia work; hardware restoration to exploring legacy networking... or just plain dicking around. It really doesn't matter what you do, just so long as you do it.
While the RetroChallenge has its competitive side, it's not really a contest... it's more like global thermonuclear war ? everyone can play, but nobody really wins.
Come on... give it a go!
The summer retrochallenge runs for the month of July.

I still have many many many large tomes and other printed material, including vintage docs, that needs to be committed to digital format. I'm always building something, and I gathered a hodge podge of materials in an attempt to fenagle my own document feeder (first thought I'd use a scanner or pair, later said screw that I'll just use a digital camera). Non destructive scanning isn't necessarily a whole lot more difficult in my estimation (using whatever curdled gray matter I have left), but who needs any more complexity then is necessary, so I opted for destructive scanning (where you rip the spine of the book apart and jam it in the mechanism). Then strolling through Target, I noticed the Epson Workforce 645 which allegedly can take a stack of 30 sheets and scan both sides. I'd prefer 30,000 sheets, but beggars can't always be choosers. So I bought it, but have yet to open it (my ethic states I shouldn't crack an item unless I'm somewhat positive I'll
keep it. I _rarely_ return something I open. It bothers me to). So I would just like to ask if any of you all have delved into this. A piddly 30 sheet document feeder still requires you to "be there", although I suppose I could catch up on twiddling my thumbs at least while I reduce oh 300 books to bits and bytes.
No the unit I already returned (unopened) wasnt designed for big batches or even longevity necessarily, but document feeding, the crux of the matter, is no feat. People have and I seem to recall there even being one commercial product that turned a copier into a document scanner. Accurate and reliable document feeders are often left on the side of the road.
an awful lot of it seems to get done despite youre experience in the industry (10 years ago? 20?). We had something maybe a Canon, at a job 8 years ago, often reliably taking print and even that skinny fanfold garbage simultaneously. Did it draw 2 pages in periodically, short of spending ~a grand, Im sure anything will. I would think an 80-90% percent success rate for a relatively short job (i.e not long term professional activity) would be tolerable. You can always manually redo those wayfaring missed pages. This forum has nearly nothing to do with anything professional. But anything, including hobbies warrants some patience. And dumping significant cash or having people tell you it cant be done otherwise doesnt make sense.

Here's an update from the KryoFlux team and it's for sure the hottest
thing that I have been given the pleasure to reveal over the last
twelve months. The post is long, but we have been very productive. :)
You might have noticed it's gotten a bit quiet after adding write
support to KryoFlux last summer. The reason is that behind the scenes
the next big thing has been prepared. We always felt that the C64
community was lacking a format that would give them the opportunity to
feed raw data more or less reliably into emulation. It turned out that
G64 was in fact capable of working for an estimated 95% of all
scenarios out there, but implementation in many emulators is so bad
that things the format has to offer simply don't work in emulation.
It's been a while since we said we'd not touch G64 as G64 was "bad",
"not working" and "giving people a false impression about preserving
things". While we stand firm that G64 is not the grail of a
preservation format, we must apologise for being stubborn in regard to
supporting it. Gladly many of you were stubborn, too, requesting G64
being supported, which finally led to the decision to do it right and
correct things as needed.
We turned to?Pete Rittwage?and his?C64 Preservation Project. We in
fact?had been in touch for years and we were happy Pete shared the
vision we?had and decided to not let us have the fun on our own:?"I am
more than?happy to?help push technology forward. ?I knew the
limitations of what I was doing?with the old 1541 hardware and was
excited to hear that work was being?done on the 64 with Kryoflux. ?I
was glad to fill a gap until more?high-resolution disk imaging was
available."? While this is flattering, it?would be an understatement
to call Pete's work a gap filler - his NibTools?are very much
appreciated among the C64 community. Another helping hand came from
Robert McIntyre?who already had helped modifying 5.25" drives to allow
for one-pass dumping of flippy disks.?The following months were spent
on research and getting things done, which finally led to a few
conclusions:
a. C64 preservation is still possible today, but results largely
depend on media quality and storage.
b. About 90% of games can be imaged with a 1541, 95% can be imaged
with KryoFlux and the last 5% can be imaged with KryoFlux as well, but
representation will need a more sophisticated format like our own IPF.
c. Nearly all emulators are "broken" in regard to G64 image support.
While some will go beyond the limit of 7928 bytes per track (which
seems to be the maximum track size chosen by many programmers), some
even don't support half tracks. This protection technique utilises the
fact that the 1541 has a head designed for a 40 track drive, but
features a stepping mechanism that can address 80 tracks. VICE, the
most popular, has several flaws in the floppy support code which makes
it impossible to use such images unaltered.
If you take the time to read Pete's pages
(http://www.c64preservation.com/) you will find many details on how to
modify or alter images to make them work in emulation. While some
changes are needed because the 1541 alters data before handing it over
to the host computer (which means this also happens with other devices
that work directly with it) the other half of changes are needed to
work around flaws present in certain emulators.
We decided it would not make much sense to release KryoFlux with
capabilities that would go beyond those of the emulators around which
is why we decided to also update VICE and give it extended G64 support
to load many images properly without any user interaction.?While
Softpres' Istv?n F?bi?n worked on creating an intelligent conversion
algorithm for DTC that would transform stream data into meaningful G64
representations, Robert focussed on exorcising VICE and fix/add the
features needed to make the 1541 in VICE behave like the real device.
To give the emulation the precision needed to also run the most
advanced protection methods, the trio even delved into the schematics
and created a logic model that was verified shortly after by Pete by
writing special test files back to disk with modified versions of
Nibtools and then comparing results. The data was seen as predicted.
So, after many months of research and hard work, about 1,000 C64 games
dumped, and many many emails later, we are proud to present:
1. DTC with enhanced G64 export.?Rated in percent, the success should
be good for 85%. Please make sure to not toss your stream files (which
are mandatory for generating G64 files) - you might need them to fix
images that won't work when we release the next version. If you get an
error telling you there was a problem converting to G64 - be sure
there was and the image is bad. DTC will refuse to convert to G64
directly from a floppy disk. You must create STREAM files first, to
avoid unnecessary stress applied to the ageing medium. Please read the
manual (especially page 19 and 20) about how this new exciting feature
works.
2. PREVIEW version of VICE with enhanced G64 support.?This is our
special gift to the community, and we're sure many users will
appreciate it. You won't need a KryoFlux to benefit from it, many
images that are floating around and needed to be fixed will now work
right away. We'll hopefully be working with the VICE team to get our
updates included in the official sources, but until that happens?we'll
continue to provide a second fork (W32 build as of today, source code)
on our site which will have extended G64 support.?The new circuitry
simulation code allows VICE to read data recorded at a?certain bitcell
density to be read back at a different bitcell density.?e.g. data
recorded at 3.5us to be read back at 3.5us correctly as well?as get
the expected results when reading at say 3.25us timing setting. E.g.
all RapidLok protected titles rely on this to be working ?Please note
that this preview does not yet enable half-track support, which will
come in an update within the next month. Please see the README file
included with the builds for further limitations, this still is a
PREVIEW version.
Here is a picture of a game that for sure won't run on an unmodified
version of VICE: "Defender Of The Crown" by Cinemaware.
http://kryoflux.com/pics/dotc_raiding.jpg
It features?V-MAX! v2 protection and performs a precise density check
on the disk as?soon as the player goes raiding. This image will not
run in the current?official build of VICE. To give you a chance to try
this new feature,?the G64 for "Defender Of The Crown", courtesy of CW
Holdings, Inc., is?included with the VICE build on our website. The
new build of VICE will?also run many other G64 files now that did fail
before. If you ever?tried some of?the early Rainbow Arts or Magic
Bytes titles (so called?BetaSkip protection by MWS), like Giana
Sisters, Turrican or Blue Angel?69... all of these should work
flawlessly now.
All of the above is available as of today. Just head over to
http://www.kryoflux.com?and grab the download of your choice.
We'd love to hear your thoughts on this. Please visit our forums (

Retrocomputing with a VAMP stack: VAX, Apache, MySQL & PHP
What to do with a VAX workstation, based on an architecture first
released by Digital Equipment Corporation in 1977 and finally closed
out by Compaq at the end of the last millennium?
The obvious option would be to dig out an ancient copy of VMS, or
maybe an early UNIX tape, but what then? Could it run the latest
Apache or screen, and how will I be able to connect it to a native
IPv6 network (when we finally get there :) ?
As an alternative, lets see if a current OS and software can run on a
machine with an architecture older than some of the *parents* of
modern developers...

Is there a reference somewhere that tells me exactly the spec of various DEC
cables?
For example I think I need a BC13B (connects VCB02 to monitor, keyboard and
mouse), but I have a BC19S which *seems* identical. All I can find are
resellers that list part numbers, one or two name the cables, but don't give
the technical information that gives me any idea if these two are
interchangeable or not.

Whatsoever a man soweth, that shall he also reap...The truth is always simple.
I have looked through bitsavers and some other old vax manual repositories online and I haven't found a manual for the DEC VT1300. I did an installation and service manual for the VR320 monitors I have, but they only cover the display. I have worked out alot of details about the vt1300 system, and have gotten one working 100%, but haven't figured out what terminal emulation the terminal personality of the unit uses. It works 95% with the vax 3900 I have it attached to, but from time to time I see what I assume as vt100 control codes in the output stream. I assumed that that unit used vt100 emulation out of the box, and that the vax console would go this way as well, but perhaps I'm wrong. It could be that the vax is vt52 some other terminal type by default, or that the 1300 does vt102, or vt220...

I'm working on it for RaspberryPi, the procedure, minus the part about
preparing the OS SDHC card, is likely to be similar.

Sounds like an unteresting project, it could really prove viable with
something like a 4-thread i3 or i5 and 4GB of RAM to share out between
the VMs. I'd probably run a SSD or high speed disk for the partitions
to maximise I/O speed.

And someone mentioned another driver chip that can tri-state the drivers.
I once worked in an environment that kinda used that feature
to allow many RS232 devices to share one line.
It was a broadcast-mostly hub-network where clients could
send requests, but they were normally transmit-disabled.
It was collision NON-detect: lack of an ack implied a transmit collision.
Mfgrs such as Black Box also made MSU: Modem Sharing Unit.
The dumb ones just "or-ed" together the inputs.
The "smart" ones used a protocol for
multiplexing many serial ports to one.
I guess EIA-422 or 485 would be better suited for that,
but I suspect the network evolved

You (Chuck) and Dave are speaking specifically of so called 100% clones. That I fully expect to be a given. That there exists the mechanism to default to a batch of code in a rom address is news to me though, even in a hundred percenter. But since there is so much compatibility amongst BASICS, as was mentioned recently, and given an empty socket (curious to know which mobos had them, probably few if any) or a board that would extend an existing socket, is it likely an IBM chip would work, even if you had to manually transfer execution.
Does any one have a pinout of the DB37 SCSI connector?
Might be what my old scanner has on it. Especially if all the ground pins
and shields line up.
Thanks!
I?ve completed a list of boards in the P800 haul:
CPU BOX 1 ? labeled P859
? CP7RA : 5111 199 62019 (P857R/A CPU for P858,P859)

? BIGD : 5111 199 73289 (Big disk (40/80MB CDC) controller)
? BIGD2A : 5111 199 57852 (Big disk)
The weirdness of Box 2 is ? obviously ? a second CPU in the same box. This
can?t be right.
CPU BOX 3 ? labeled P859
? CP7R : 5111 199 67589 (P857R CPU for P858,P859)

Box 3 has three cards with part numbers in different series from the normal
5111 199 xxxxx
CPU BOX 4 ? unlabeled, P856 type M4M box
? 2 x CDD : 5111 199 78176

? MMU : 5111 199 75183 (Memory Management Unit)
? GPC : 5111 199 79382 (Custom card)
Box 4 just looks wrong. I don?t know what the CDD cards are, but there
doesn?t appear to be a CPU or memory in there. However, there are P856 CPU?s
in the spare cards box, and I found references to the P856 being able to use
MOS memory as well as core, so all might not be lost here.
EXPANSION BOX ? E2 type (6 slots)

Looks like I should be able to get a few systems going with these parts.
There?s also a second box with spare cards, having different formats. Some
of these are double eurocard format, like those used in the P85xE systems.
There?s also a spare power supply for a P859 box, as well as a spare power
supply for a P856 box.
I?m interested in finding out more about the cards I couldn?t identify,
these are:

I?m hoping CDD means Cartridge Disc Drive, and that these are the
controllers for the X1215 disk drives.
The 2 8? floppy disk drives are CDC BR8A8A type, looks like they are 800KB
double sided, double density drives. They?re very dusty.

just noticed my 3 rl02's i have ones a rl02a witch has a metal front panel
instead of plastic what els is different not seeing anything on a quick
google
Just acquired a PC 7300 and as I am cursed with always incomplete
keyboards would be interested if anyone has spare keycaps for it
please.
I am missing the letter C keycap and the Reset/Break keycap.
Example picture: http://upload.wikimedia.org/wikipedia/commons/e/e6/Att-3b1.JPG
I can offer VT100-style keycaps as a trade or paypal.

I hope you tweet about mine, I will be blogging it as I go and posting
video hopefully so plenty of interest! :) Follow @DECtecInfo :)
Hopefully mine will have more nodes and will be rack-mountable with
ports to the outside world... maybe ;)

Marklar was, of course, the Intel version of OS X which existed in Apple's
skunkworks after the apparent demise of Star Trek (classic OS on x86). I say
apparent, because this post, allegedly written by the wife of the chief
engineer, implies that Marklar rose from the ashes of Star Trek due to this

Down in Macon, GA my dad has a DEC that we would like to send to a good
home. He purchased this several years ago from a man in north
Georgia who said it spend the 1990s answering the phone at a utility
company. My dad kept it in his classroom while he was a high school
technology teacher, but now that he's no longer teaching it's gathering
dust on his carport.
There's a VAXstation 3, DECvoice unit, two hard drives, and a tape drive
in an enclosure on wheels. There's also a VT420 terminal. You'd need a
truck, ramp, and at least two strong people to load and unload this.
You can see some pictures of the equipment at

The example I know, is the MK11 memory box.
ECC there is done at the single-error correction, double-error detection level on 32-bit words.
This takes 7 check bits.
I find the most satisfying illustration to be the MK11B print set, there's a very nice 11x17
page in large type, illustrating how all this is done with XOR gates. I find this much more digestible
than the usual mathematical equation stuff found in textbooks. That's a brilliant page.
It shows how to, by eye, to read the XOR gate outputs to identify the error syndrome uniquely,
with just a few words. Many fewer words than I used in this paragraph!!!!
If you didn't want double-error detection it would take 6 check bits per 32 bit word. Maybe
the implication that there is 3 check bits per 16 bit words, assumes single-bit correction
and the actual ECC logic is working on 32 bit words. If the ECC was working on 16 bit words,
it would take 5 check bits.

Ill wager they must have been very illegal clones Diane. Do you remember anymore specifics? And with her statement I dare anyone to tell me the real early even vanilla clones arent collectible.
assuming an empty socket (IBM mobos typically have empty sockets), chances are if you dropped IBM roms into a clone mobo, while it may not boot into BASIC in the absence of a floppy or hard drive, would it work if you jumped to so and so?

I am wondering jsut what a '300 baud interface' is if not a serial port.
It sounds like it might be a current loop interface. I thought the Model
43 had both that and RS232 as standrd, but it does depened on the PCB at
the very back, behind the PSU.
I _think_ that standard Model 43s can do 110 or 300 baud.

I don't know what happened but I suspect it might have been something
to do with the Oracle takeover. This has caused problems with Java use
on Linux, for example. Oracle won't permit others to host the JVM in a
repository any more, for instance.

ZFS in OSX died due to SUNW->ORCL licensing changes, IIRC.
Oh no! Not another baud .vs.BPS.vs.data rate gentleman's argument!
But, What is a 300 Baud interface? Current loop maybe?

I was at a storage unit this evening, picking up yet another couple of
free DEC machines. The guy unloading the machines also had a couple of
teletypes. One was a pretty standard Model 43 (all plastic case).
It had a 300 baud interface, not serial port. He said he knows it works
because he ran it to a computer at 300 baud that then converted the

300 baud interface makes it more of a pain, but more cool at the same

all metal, built into a small table, had an Army Corps label, a tape
read/writer?, a box of blank "new" paper tapes on spools about 5/8 inch

12 inches wide. The secondary teletype had keys too, but I am thinking
the primary with the paper tape was used for input and the secondary
was used for output. The guy said it was used with the MARS system.
There was an interface box too, probably to connect to a ham radio,
but the radio was not present. The guy said he got it from a retired
Air Force General who had kept it as a souvenir. He said he has all the
original manuals that go with it at home. He said it is complete and

However considering the year, 1938, it was in remarkably good shape.
The dry Colorado air is pretty easy on most equipment, and this was
yet another example of that.
He said cannot ship it because it is too heavy, but I know that places
like "The UPS Store" can pickup, package, and ship items like this.
There is a UPS Store nearby that might be able to do the job. (I had
a 100+ lb IBM machine shipped this way a few years ago for about $200).
Anyway, the guy is Matt. I am not going to post his email address, but
if you want to contact him, email me and I will forward your email to

took some pictures with his smartphone for me, and once he emails those,
