The best way to write QD media is to use a TEACFD55GFV or
FD55F as both work. Then the actual media is the BROWN or
360k stuff that has been bulk erased. The resulting disks will
be reliable aswsuming the drive hasn't been munged or the
formating incorrect. A PC FDC can drive these drives and
will/can format them.
You will need a utility program that does disk reading and
formatting with CP/M formats.
FYI: the TEAC drives are my favorite for any 80track format
either single or double sided. I use them as substition
for RX50s as well.

The SB-180s used them. A lot of the later CPM and early MS-DOS (but not
necessarily IBM compatible) machines used them. For example, they were
popular additons to the Sanyo 55xs. I just found a pair of Teac 80 track
drives inside of an old Multibus system (The same one that had the GAPP
cards in it).

Yes, MS-DOS can handle them. There's a DOS device driver that I can't
think of the name of but it will let you specify the number of sides,
tracks and sectors. It will handle them nicely.

225s and 251s are handy to keep around since they'll replace a number of
OLD hard drives. I've used 225s to replace the dries inside of some of the
HP HP-IB disk drives.

... back again with my periodic thread on System/36 IBM mini-computers...
When I last left you... we were all bitching about SPAM. This week... we're
bitching about SPAM?!
The 5362 is in good health, and I've started to fool around with actually
using it. As soon as I can find the LAN interface for it I'll integrate
into the rest of my motteley managerie on line (the better to play with
over VPN while travelling). To get to this point I hacked the security
file, deliberately corrupted the VTOC and re-installed the SSP. I found
scanning the disk sector by sector for appropriate files an... experience.
Worked though.
The 5360 was successfully moved from a printers workshop into it's
temporary storage unit. My back is recovering. The U-Haul van started
mysteriously burning oil. Co-incidence? You be the judge. Can't say as I've
powered her up -- or even done a proper inventory of part numbers. I'm sure
that's all something to look forward to, or at least it will be next time I
can spare the day to drive down to Hartford.
The 5363 arrived while I was away on client site. I get power and error
messages on it right now. Still investigating....
Steve Robertson gets gold stars for his assist along the way. I've acquired
his set of System/36 documentation. Slowly it makes it's way across my
scanner. The prospect of buying a page feeder gets more appealing every
page.
Which leads me to the subject line of this e-mail: I have the SSP set on 8"
disk, but that's not only a different format but a different version than
what's supposed to be used on the late System/36 like a 5363. The 5363
continued to add version numbers to the SSP in a 5.25" version. The 8"
stopped around V5. I'd like to bring the 5363 around, but I could use some
additional tools to do it. Anyone out there holding onto a 5.25" SSP set?
Warmest, SPAM-free regards,

Speaking as someone who did this many years ago (duplicated MV DIAG TK50)
it is not a simple dd job. You have to copy the entire structure of
the tape, which is something like
<tape header> [<file header> <file contents> <file trailer>] <tape trailer>
Repeat section between [ ] as many times as there are files on the tape.
Each header and trailer block is (I think) 80 bytes, and there are
FileMarks at the end of each and every header, trailer, and contents.

Anyone know what a Dilog DQ-634 does? I haven't found any information on
the Net except for a couple of places that have them for sale.
It obviously interfaces two MFM drives, due to the connectors

DQ-614, which emulates RL01/RL02s?
Thanks,

Re Where does the 600v come from?
The SMPSU in question is probably of the 'Flyback' or of the 'Forward Converter' type. In either case the converter O/P Tx primary winding is connected between the +300vdc rail and the collector of the switching transistor. The emitter of the switching transistor is connected by a small resistor to the 0v (-tve) rail.
During the conducting period of the switching transistor (lets call it TR4 - it often is) the potential across TR4 is very low, a few volts. Hence virtually all of the 300vdc appears across the primary winding of the O/P converter Tx (lets call it Tx1). The collector of TR4 is therefore at -300vdc.
When TR4 is driven into its 'off' period Lenz's Law causes the primary inductance of Tx1 to try to maintain the primary current. The resultant induced emf (due to collapse of primary flux) now produces a +tve potential at the Tr4 collector and a -tve potential at the +dc rail end of Tx1 primary. Hence the Tr4 collector is now 300vdc positive to the +300vdc rail.
Therefore the collector of Tr4 is now 600v +tve to the 0v (-tve) rail ofv the PSU. Don't touch its Heatsink while the PSU is switched on. Also allow 4 or 5 mins for the voltages to bleed down after switching the PSU off before touching internal components. (It should give this warning on its nameplate)
Hope this is clear and useful - it is 3.30am in the morning here in UK.

I don't think they are GCR but someone more knowledgeable than I will have to
answer that. My understanding is that they are the same as a 360 drive with a
head that is half the width so they can deal with 80 tracks instead of 40.

The answer to this is yes. For many years I kept an IBM PC (8088) clone with
DSDD, DSQD drives and my EPROM programmer. IIRC I used the 3 1/2 inch 720K
disk driver for the DSQD and it worked for my purposes of making disks for
various systems. I used Media Master (sorry Fred) and PCDOS 3.3.
Many systems of the MPM era used DSQDs, some single user computers like the
Kaypro 4, too.
The Intel 310s used DSQDs also. This is where most of mine came from. I still
have a few 310s and DSQDs.

Bleh. MDR's mailserver is down, and I can't get in to fix it till
Monday.
Well, the Altos 580 ended up costing me $5 and "a future favor".
Tyler couldn't find any of the floppy disks for it.
It looks fine inside, except that the case fan was unplugged from the
PSU. After finding the power header & plugging it in, I understand
that.
It does speak VT100, on RS232 port "JC" (Thanks, Andreas!) and boots to
"Boot Monitor v7.03". Passes system tests, and attempts to boot from
the hard drive. The activity light on the floppy drive comes on and
stays on.
I don't think the hard drive, a CMI CM-5619, is powering up at all.
If it is it's incredibly quiet....
Anyway, I don't have any way to test the system. I did find an
archive of MP/M II for it, but the zip file isn't in any image format.
Does anyone have the install disks, and the Diagnostics/utilities
disk, or disk images? And a way to create the disks on a Linux box?
They are DD/DS floppies, right?
Does this thing care what MFM disk it has?
More junkyard fun....

DSQD generally means 80 track two sided drives such as
TEAC FD55F or G and double density encoding. Typically
they store around 800k.
FYI that can mean hard or softsectored as that is controller
not drive dependent.

My work on the emulator for the HP2100 and 21MX computer systems (and all applicable peripherals and interface cards) is reaching a point soon where I would like to solicit someone to help me with compilation testing on various unix platforms. I am doing the development and testing on FreeBSD, so of course I know it will work there. I am hoping that some list members can provide me with remote access to different unix platforms so I can make sure that it will compile correctly. I would like to make sure it will work on Sun, Linux, and HP-UX as well. I have access to quite a few HP-UX machines, but not Linux or Sun. Being a staunch FreeBSD bigot, I have no desire to install Linux myself. The emulator depends heavily on the implementation of fork(), execl(), and SYSV IPC mechanisms such as message queues. I have heard that there are some differences in the implementation of fork() on Linux for example.
At the outset I wanted very badly to allow it to work on DOS/Windows platforms, but later in the design phase it became apparent for a variety of reasons that this simply isn't feasible, unless someone knows of a way to use SYSV IPC stuff there.
If anyone can allow me remote access to these type of machines, please contact me offlist.

The problem with the mail servers has been found and fixed. Turns out it wasn't due to the changes I had made. One of the open relay databases that we use for checking smtp servers that we will converse with is currently out of service it seems (mail-abuse.org). As a result, all the "dns"-style lookups our mail server would do to them to check for open relays would timeout. I removed the check for that service temporarily until it's disposition is known. Fear not - we have other services we check for open relay as well and they are still in effect.

What timing *sigh*
I just noticed this morning that there is a rather severe problem with both our primary and secondary mail servers for the classiccmp.org domain. I must admit with much chagrin that it appears to be one of a set of changes that I made a week or two ago, but only manifested itself this morning. I am not sure of exactly which change caused the problem, but I have been working on it all day and will continue to do so till the problem is fixed.
Symptoms - inbound connections from remote mail servers experience a long delay after the connection is made before sendmail acknowledges the connection. Most of the time the mail goes through, but the long pause bothers me. Other times the remote mail server times out, and retries later, but gets through. As a result, it appears that mail is going through but is significantly delayed. The error message is the typical "timeout waiting for..... during client greeting". No, the problem is definitely not reverse DNS (ident) or low level network related - the typical causes for that problem.
I will post to the list once the problem is resolved, unless I choose to finally get some sleep.

I have used ExpressPCB and the free layout software on two projects. The
layout software is for Windows and does double sided boards only. This
software emails the design to ExpressPCB so it is not general purpose.
If a two layer board will meet your needs I recommend ExpressPCB. Their
service is fast and the software is easy to use.
http://www.expresspcb.com
Two 10 by 10 boards with no solder mask are +ACQ-230 (+ACQ-70 setup, +ACQ-80 per board)
with a 3 day delivery.
Two 10 by 10 boards with silk screen and solder mask are +ACQ-370 (+ACQ-310 setup,
+ACQ-27 per board) with a 10 day delivery
Boards up to 5.25 by 4 with silk screen and solder mask are +ACQ-229 for 5
boards.
The company also offers a full featured PCB board production service. Your
boards are actually manufactured here.
http://www.pcbexpress.com/
I have access to commercial grade design software (PADS PowerPCB) but it is
very difficult to get up to speed on the full featured software if you are
doing one design a year. If you mess up on producing your output files your
boards are junk. It is difficult to make operator errors in the ExpressPCB
software. (You can still route the trace to the wrong pin.)

Here's a picture from 1966 of an IBM computer at the IBM computing center on
Manhattan (New York City, New York USA). The text for the photo says that
the computer is being used to make a payroll calculation.
Visible are 4 big-fridge-sized reel-reel tape devices, the console with
operator seated at it, and some other things in the background.
What's the computer model? Does anybody know who this guy (operator)
is/was?
Just a neat photo.

I've used ExpressPCB...just last week, as a matter of fact. Their
boards are quite decent, and their service is fast and predictable.

The trouble ALWAYS starts when someone posts an
opinion to the list. An opinion is not a question,
or an answer. It's not news or information. It's not
a recollection and it's not history. It's not on topic.
Opinions are unavoidable, but self control (and
counting to 50,000) can really cut down on the
noise.

This is doable. Though most of the LK201s had 8051 chips and you
could program a 8751 and put that in if you like.

Hi,
I have a PDP-11/34 programmer's console but no PDP-11/34, what
should I do with it? My options are:
1) get a PDP-11/34
2) trade it with something I need more, like a PDP-8/A power
regulator(G8018) and limited function panel so that I can
build my third PDP-8/A :-)
PDP-11s were never really my plan to collect, but I wouldn't
mind having one specimen of 2.9 BSD running. So, may be I
should get an 11/34?
cheers,

Help - What am I doing wrong?
I sent the following response (SEE AFTER DOUBLE LINES of ======)
to a previous e-mail in respect of auction:
http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=2006598832
This time he did not even reply. Am I being overly cautious is making
sure that the correct customs documents are used?
Previously, we have agreed on the Shipping, Handling and insurance
to be $ 24.45 and that he would ship to Canada, but for some reason
which I can't understand, he seems to think that using the GREEN CN-22
or a COMMERCIAL INVOICE is not a reasonable requirement.
While the shipping seems a bit high, I did not quibble and agreed to
pay what was asked.
His Positive feedback seems satisfactory, so what could the problem be?
His name and address are:
Bobert1959(a)aol.com
Bob Bruns
6334 Alta Oaks Dr
Garland, TX 75043
However, this information seems to not be traceable.
Is there anyone at eBay whom I can contact?
Any other suggestions?
Sincerely yours,
Jerome Fine
MY RESPONSE TO HIS E-MAIL FOLLOWS:
Bob Burns does not reply.

Jerome Fine replies:
If everything in this e-mail is satisfactory, please respond with
"Confirmed" as the first word in the body of your reply.
Also, please add if you wish me to prepare the COMMERCIAL
INVOICE for you.
Your reply seems to suggest that by requesting that you comply with
shipping requirements at port of entry into Canada (and probably
any country - although I am not familiar with regulations elsewhere),
I am changing the terms of the auction. I hope that this reply will
help you to understand that the terms of the auction are not
part of the requirements for shipping the drive and that I have
nothing to do with these requirements.
In addition, if you read my last e-mail carefully, all that you have
been asked to do is to correctly provide the value of the item
to the customs officials in Canada. When a package is sent via
USPS, then I understand that a GREEN CN-22 form is used.
However, since I am not aware of exactly how USPS handles
air shipments, I may be incorrect. In that case, customs officials
in Canada may require a "Commercial Invoice" which is filled
out (based on my limited understanding) as a simple paper with:
===================================
COMMERCIAL INVOICE
Your Name, Address and phone contact number
My Name, Address and phone contact number
Value of the Drive: $ US 11.50
===================================
It is that simple. I don't set the requirements.
Here is my part if you need to send a Commercial Invoice:
Fine Services & Co. Ltd.
PST Exempt - 1531 2240
2 Inglis Gate
Willowdale, Ontario, Canada M2R 3G3
Attention: Jerome Fine (416) 667-8233
Please note that ALL FIVE lines are essential
for the complete address and contact phone number.
In addition, ALL FIVE lines are essential on the
outside of the box and on any shipping document.
I will include this information on a sheet of paper
which I will include with the money order and the
auction Item Number 2006598832. All you
will need to do if a Commercial Invoice is required
is to add your contact phone number to your
name and address plus the actual value of the
eBay auction.
Again, I don't set the shipping arrangements - they
are imposed by Canadian Customs at the port of
entry. I you wish, I can prepare the COMMERCIAL
INVOICE for you - all you will need to do is add your
contact phone number to the paper.
I anticipate that you don't wish to violate the requirements
that Customs Canada imposes. I certainly don't think
that a COMMERCIAL INVOICE is a difficult requirement
since it takes less than a minute to fill out. All of our e-mails
have certainly taken much longer. Certainly I have never
encountered anyone who has ever refused to provide
a COMMERCIAL INVOICE to Canadian Customs
since all of the information is normally available in any
case, just not consolidated onto the form which they
insist on - although I agree it is a pain in the posterior
if you ask my opinion.
Sincerely yours,
Jerome Fine

I, too, appreciate the work Jay has done on the list. I use this list as an
example of a large well managed community. Even though there has been a
slight increase of Spam recently it is way, way, way below any other list. We
generate more Spam about the Spam than the originators.
I am not in favor of closing the list just like I am not in favor of closing
the community. Some times moderation is necessary but in IMHO less is best. I
believe in self moderation, something we seem to be falling down on lately.
If we do not reply to or about the Spam it will be hardly noticeable. And
here I am adding to it.
I would rather learn about how to attack Spam at it's source. I am learning
how to decipher the mail headers. I need to figure out how to automate
complaint letters. From what I have seen the direct complaint to the service
provider works best.
Links to any tutorials would be appreciated, as would recommendations on SW.

I feel the need to chime in with some support for Jay. This is a
high-traffic list with a lot of recipients, which surely takes a
nontrivial amount of bandwidth and system resources to host...people
shouldn't lose sight of that fact. I run a couple of fairly large
mailing lists myself; something like this isn't a "set it and forget
it" thing...Spam is the least of the problems, most of the time.
People with crappy network connections whose mail gets backed up and
queued, Windows programs that screw up everything in sight when moving
mail around, twenty-line messages turning into 50Kbytes due to rampant
Microsoft HTMLization bogging down the mail server, etc etc etc. It's
a pain in the ass, and it takes a certain amount of babysitting to
keep things running smoothly.
Jay does a fine job. He may not have started this list, but he runs
it now...and that counts for a lot.
I hate spam as much as anyone. Actually, I hate spam a lot MORE than
most for various reasons. But guess what...My mailer has a "delete"
function, and I actually know how to use it! Wow, what a concept.
I know, I know..."but spam slows down my net connection!" If your net
connection sucks so badly that a little (or a lot) of spam bogs it
down, then get something faster. There's no real excuse in this day
and age. Spam blows dog, there's no question about it...but it's a
fact of life on the internet today. Everyone should fight it whenever
and wherever they can, but you WILL get spam if you have an email
address. The sooner people learn to deal with that, the happier
everyone will be.
Further...there are lots of off-topic conversations on this mailing
list. I take part in many of them, so I'm as guilty as anyone. But
you know what? Humans are social animals, and this list is a social
thing. Many of you are my friends. If there's an off-topic
discussion here that you don't want to take part in, well, use that
magical "delete" key...Every mailer has one.
In other words...if anyone here has a life that's so utterly perfect
that spam and off-topic discussions can offset the friendship,
comeradery, education, and other classiccmp benefits, I'll swap lives
with you any day of the week.
Sheesh.

I say OT because some of this applies to newer machines, but I
thought it might me worth sharing.
I was in a tinkering mood yesterday. I had recently pulled the 256 mb
(three dinky DIMMS) from a Pentium II and put in two 256 mb sticks.
My motherboard docs state a max of 512 mb, but now I got a spare memory
socket and could not resist. I stuck another 32 mb in and fired it up.
The BIOS self test ran OK, and it booted to DOS find. But when I brought
Microslop Windoze 95, I learned the true meaning of Windoze. You could
click on the start button, take a drink of coffee, light up a smoke, and
maybe, just maybe, the start menu would appear by the time you did that.
A whole new meaning to the word slow.
Needless to say, I pulled the 32 mb. Windoze returned to its 'normal'
speed.
Not content to stop there, I decided to up the size of the ramdisk from
16 mb to 32 mb. Since I boot to the DOS prompt, it was easy to catch the
error stating invalid ramdisk parameter. So I took it back to 16 mb and
starting incrementing it. I got all the way to 30 mb with no problems,
or so I thought. I had only booted to DOS, and not brought up Win95
during the time. With a 30 mb ramdisk I brought it up. My display settings
were changed and the display adapter was complaining. I returned the
ramdisk to 16 mb and all returned to normal.
I found nothing on a specific limit on a ramdisk in any docs I looked
at. I have used a ramdisk since my XT days. Now it is almost like they
don't want us to know about it.
Any thoughts?
----------------------------------------
I also have been trying to add some memory to an old Gateway 486/33 machine
I use for utility things. It already has 16 mb. I've tried several
combinations of SIMMS all meeting GW requirements (36 bit parity 70 ns).
It comes down to no matter what combination I put in, nor how I set the
memory dip switches, it won't recognize anything beyond 16 mb. I have
the manual of this beast, and it clearly states it is expandable to 64 mb.
----------------------------------------
And finally, I was confused by the recent posting on the DEC 3000/300.
The reason was that someone handed me a bag of DEC SIMMS some time back
and I thought they were for a 3000 but the descriptions in the recent
posting dod not jive with what I had. The ones I have are 100 pin,
10 chip, 70ns and are a 4 mb module with room for another 4 mb on the
back. It would seem that mine are for the 3000/400 and maybe higher.

I have just been given a Display Writer system complete with CPU,
Keyboard, Monitor, Dual 8" floppy drive and some floppy disks. I have been
told it works but I haven't tested it myself yet. It is surplus to my
requirements so if anybody wants it they can have it. I can test it if
there is interest.

I'm in total agreement with this. Believe it or not, each and

Yes, that sounds exactly like it. Usually they have stuff standing there for a
few months, but this one was gone pretty quick. They normally have lots of
weird computer systems (not at the moment; I checked last Friday and it was
almost empty), but I tend to stick to the smaller systems; mostly what you see
are industrial controllers in 2m tall 19" racks....

John F. Auwaerter,76,
Pioneer who helped create computer language
by Krystyna Slivinski
Special to the Tribune
John F. Auwaerter, 76, of Park Ridge, was a pioneer in the
telecommunications industry who was instrumental in the development of
the American Standard Code for Information Interchange, or the ASCII
computer language.
The code was the first 8-bit standard code that allowed characters, such
as those found on a keyboard, to be represented by the same codes on
many different kinds of computers.
"That was a major change in standardization for the telecommunications
industry," said Sylvan Silberg, a fellow former research engineer at
Teletype Corp. The code was developed in the 1960s through Mr.
Auwaerter's involvement an Institute of Electrical Engineers committee,
Silberg said.
"He traveled all over the world defining what this code would represent.
This is the code that is still used in PCs today," Silberg said.
Mr. Auwaerter died of cancer Saturday, Feb. 23, in Fountain Hill, Ariz.
Born in Chicago, Mr. Auwaerter served two years in the Navy as an ensign
stationed in the Pacific in World War II. He was a graduate of
Northwestern University in Evanston, where he received a bachelor's
degree in electrical engineering in the late 1950s. After working as an
engineer at General Electric in Baltimore, Mr. Auwaerter joined Teletype
Corp. in Chicago.
At the same time, he attended DePaul University and got a law degree in
the late 1950s. Despite the law degree, Mr. Auwaerter's career remained
focused on telecommunications.
During the late 1950s, he was responsible for developing a nationwide
network that provided up-to-date weather reports every 15 minutes, which
teletypes supplied to the Federal Aviation Administration.
"He knew how to get the most out of people and make them love it,"
Silberg said.
His other achievements included the creation of a secure high-speed
communication network for the federal government in the 1960s. He
retired from Teletype in the early 1980s as vice president of sales.
"He was quite dynamic and brilliant," said his daughter, Mary Loftus.
"He was in charge in whatever he got involved in."
Other survivors include two grandchildren.
A memorial service will begin at 11a.m. Friday in St. Paul if the Cross
Catholic Church, 320 S. Washington Ave., Park Ridge.

Seems to me that nearly all ribbon cables use even-numbered pins for
signal and odd-numbered pins for ground. So signal and ground lines
alternate in the cable.

Okay. I'm probably the last person still using Microsoft Mail. It works
okay, but I can't find any information about security holes (or lack of
them) in this program, and it does not include the headers in messages
which I forward, so it's no good for reporting spam.
Sellam, I tried Pegasus v4 and the windows kept popping up in really odd
locations and sizes. It also has *way* more bells and whistles than I
need.
Doc, I tried Pine, but the Win9x version requires that I be on-line to read
email. I want to send/receive, logoff, and then read and compose new mail.
Other than that, it looks okay.
Can some one suggest a simple offline email handler that isn't giving that
"come hither" look to every Trojan on earth? And that's free?

Ancestry.com does this very effectively.
They have a message archive, but then you nring up a message,
you don't see the RFC822 e-mail address, just the name of the
poster.
Like with E-Bay, if you want the actual address, you click a
link that takes you to a different page. Here is where the
difference begins, and why Ancesrty's way is much cooler
than E-Bay's (but then _cooler than E-Bay_ isn't hard to do).
Anyway, you get a page where the host system looks up the
actual e-mail address, then constructs a graphic image
ON THE FLY that is a "picture" of the poster's e-mail
address.
Gonna take a hell of a bot to break through that...

Okay, check out:
http://home.freiepresse.de/befis/zx96_e.htm
Then tell me what you *can't* do with a ZX81 ;>)
We can:
scan documents
control overhead projectors
control CNC tools and other robotics
run BBSs
play audio CDs
load programs from CDs
burn EPROMs
In addition to the above, we also use:
AT- and PS/2-style keyboards
5.25" fdds
3.5" fdds
IDE hdds
LCD screens
I've heard that a TCP/IP protocol handler will be unveiled at this year's
meeting.
Sure, some of these operations are slow, but the point is that we're doing
a *lot* with "obsolete" hardware. If we can get this kind of functionality
out of a Z80-based system, what could *really* be done with a 486-100,
P233, or P4-2.2 GHz system, given the time and brainpower?
Sellam once said that the ZX-TEAMers were "fanatical hackers." How else is
science advanced, other than fanatical hacking (and dumb luck)?
My personal project is WIN-ZX, which will perform many of the tasks Windows
3.1 handled for the PC. Presently it requires a 64KB system with a
MEFISDOS-based IDE hard drive, but I hope to trim it down to 16KB and
cassette tape.
Hope you join us for the chat --

There are literally DOZENS of these on eBay... as long as you don't mind
3rd party ones (if you want a true apple one, you might actually have to
look a few times over the course of 2 weeks before one shows up... even
those aren't exactly rare).
But, you are right, almost all of them end up in the $20 range after
shipping (and many before shipping). Again, it isn't because of demand,
but rather because 90% of them are 3rd party, all sold by the same
person, and all with starting bids of $9.99 + $10 shipping and handling.
Almost all go unbid, but because of that, the few that get listed by
someone else for lower prices, get driven up by people trying to get a
better deal (or from the one guy slamming the bids to make his the
cheapest for all I know).

Well.. there are two different video "adaptors" that were being refered
to in that thread.
One is the HDI-45 to RGB adaptor, that came with all the "AV" powermacs
that had the AV video port. I think that was limited to the 6100, 7100,
8100 series (but may have included others). This was needed to connect a
standard RGB monitor to the HDI-45 AV video connector. Or, Apple prefered
you bought an AV monitor that plugged directly into the port and provided
video, audio, ADB, and for some reason I think color calibration (but I
might be wrong on the last one).
The other "adaptor" or dongle that was being refered to, is the Video
Loopback connector for the DOS cards. The two DOS card styles I have (the
"Houdini" from the Q610, and the later PC Compatability cards for the PCI
Powermacs), required a video cable that plugged from the DB-26 port on
the DOS card, looped into the RGB port on the Mac, and had an output for
RGB. It enabled you to use one monitor for both DOS and Mac, or if you
don't connect the loop to the Mac's RGB, you could use two monitors, one
for each world. Also, the Q610 version provided a Joystick/Game/Midi
port. That port was not on the cable for the PCI version, as the
Game/Midi port was right on the DOS card.
The question that seems to have come up is, does the 6100 DOS card have
that loopback connector at all? The PCI DOS cards can either use the the
external loop connector... OR an internal connector for Macs that support
it (you need the GIMO slot, which many of the PCI Powermacs had). There
is a possibility the 6100 card does something similar.
But, if the 6100 DOS card needs the cable, is most definitly should have
come with it. The Q610 came with it, and the PCI cards came with both the
internal AND external cables as far as I am aware (I have never bought a
PCI one new... two of mine came installed in a 4400 from Apple, and
included the external, but not internal cable, and my 3rd came installed
in a used 7200 with an internal, but not external... but the eBay ads I
have seen for boxed ones, always say they have both internal and external
cables, and since you need one or the other cable, and Apple had no way
of knowing which PCI Powermac you planned to use it with, it would have
made sense to include both styles)

There is a cable with three or four connectors attached to it; I
assume this is what you're referring to. The package is complete,
the packing list is still there, I can bring it in tomorrow and

I use dz80, which you can find at http://www.inkland.org/dz80/index.htm
I see the current version is 2.0 (March 2002), but I use 1.31 (June 1999).
Actually, I made a few small changes to make the unix version work more
like other unix software (mostly to do with option letters and arguments,
which were strange and DOS-like in the original, and to allow use of hex
and octal in addresses and output, plus a couple of bugfixes for long
jumps).

Old Atari games play on Sony Ericsson phones
Mobile phone maker Sony Ericsson on Thursday announced partnerships
with two companies making games for mobile phones in its drive to
challenge handset market leader Nokia through mobile entertainment.
The newly formed handset maker, Sony Ericsson, said partnerships with
iFone and Synergenix would enable consumers to download some games for
free from the Sony Ericsson Web site, or access others for a fee from
an operator's Web site. IFone will be providing games from its Atari
catalogue, including classics such as Asteroids and Pong. --Reuters

P.S. Happy PI day!!!
Well,
The subject says it all... I have a ROM (a 2764
I think, it came to 8K bytes) I need to render
into the most readable source code possible.
It is Z-80 executable, and contains ASCII strings
that have their high-order bits set (yes, PR1ME).
I have a few disassembler stored on some archive
somewhere. But on the chance that a lister might
know of a more modern Z-80 disassembler than what
I'm likely to have, I thought I'd post a query.
This need comes after having acquired and replaced
every single board in my Prime, only to still have
it be non-operational.
Thanks in advance,

If you can get three KA820s (or KA825s)

The Owner's Manual is available at:

as is the Installation Guide.
I *thought* I'd also scanned and sent an
install guide for one of the VAXBI ethernet
options, but I guess not.
When I had one in the lab, my VAX 8350
just mostly worked so I don't have too much
experience of playing with the ethernet.
The DSB32 and DMB32, and the CPU(s)
and memory were all pretty straightforward.
The only funny I remember with ethernet is
that you need to cable up a little bit extra
for the power required by the AUI in
the bulkhead. But that may well have been
the VAX 6000 ...

I have lots of trouble with older 68k Macs that were used
by clueless lusers... in particular, here at my current
orkplace, our #1 Mac advocate didn't realize you have to
power off the system and SCSI devices when attaching them/
removing hem from the chain. I'm not sure what goes bad after
five years of connecting/dosconnecting with the power on
(the terminator resistors shouldn't be affected, should they)?
But I run into this a lot; I have little luck with CDs
on Macs, and more trouble with outboard drives in general
than I'd care to say...

I've never heard these called "video dongles", and while they don't
come in the package with the 6100 DOS board, the manual says it's
needed, shows its picture, and says it comes with the computer in
which you're trying to install the board.
Complete package, appears not to have ever been installed, the red
Apple seal is still intact on the diskette pack (but was easily pried
open by yours truly while checking).
I think I even have a 6100 for it to go in, but dunno what I'll

Hi ho,
now I hauled it home, the modules of this very impressive MTI
StorageWare assembly. It's a marvellous piece of super redundant
24/7 operational gear for any VAX cluster. The fun starts with
a box that probably emulates an HSC90 or so, that one has two
power supplys, and there are two of those boxes each having the
4 redundant CI connectors. Each box has 3 SCSI (?) connectors
that run to another 4-box assembly and there is another layer
of redundancy. Then all this drives 4 arrays of 4GB SCSI disks
each having 8 such disks. I conclude that this must be a RAID
array, because I don't know how else one could address 8 disks
on a SCSI bus (isn't 7 devices appart from the controller the
maximum?) Initially it seemed straight-forward to use as a
simple CI/HSC to SCSI adapter, but now it looks like this stuff
is best kept as one big impressive unit. I'm going to try find
the manuals for this too. Does anyone have experience with
this kind of gear?
regards,
-Gunther

DELQAs are fairly easy to come by. If you want one and can't find
one immediately, email me.

I might have one of these, I will check. Email me if you don't hear
back about this by the end of the weekend.

Nah...that's just a *start*.

IIRC, if you hold the power button ON (slide the switch down like you are
turning it on, but hold it down), and then press the reset button inside
the battery compartment... that will wipe the system memory. That will
reset the password as well as wipe out EVERYTHING you might have had
loaded.... basically it defaults it back to factory settings. (Although,
I think any system upgrades you installed are preserved).
There is probably a tech note about this on Apple's web site, as it was a
fairly common issue back in the Newton days.

Since I have the hood open on my 8200, I thought I'd diagnose the
troubles I've been having with getting a DEBNT working in there.
The 8200 I have came with a KDB50, 4MB RAM and one CPU. Nothing
else (and was $13,000 when my former employer bought it - I just
re-found the receipt). The only serial ports are the four console
ports. No DMB32 or anything like that (not that I would mind locating
one of _those_ either).
Since it first arrived, I put in more RAM, COMBOARDs (that we made)
and a DWBUA (which I'm diagnosing for its own problems). I am now
attempting to use a DEBNT I received some time back. Here's what
it looks like inside...
T1001 KA820 - 8200 CPU
T1010 DWBUA - Unibus adapter
T1001 KA820 - 8200 CPU (not installed at present)
T1002 KDB50 - KDB50 SDI adapter
T1003 KDB50 - KDB50 Processor board
T1019 MS820-BA - 4MB RAM for VAXBI processor
T1019 MS820-BA - 4MB RAM for VAXBI processor
T1019 MS820-BA - 4MB RAM for VAXBI processor
T1008 MS820-AA - 2MB RAM for VAXBI processor
T1008 MS820-AA - 2MB RAM for VAXBI processor
1294 CBSBI - COMBOARD-BI (sync comms front end processor)
T1032 DEBNT - Ethernet and TK50 controller
(I used http://www.stmarks.pp.catholic.edu.au/vax/VAXBI.html for reference)
As you can see, it's a full boat - 16MB of RAM in 5 cards. I'd love to
run across an inexpensive MS820-CA or two. I wouldn't mind pulling the
MS820-AAs out, but 16MB is an OK amount of memory for a single user. I'm
also on a long-term quest for free or nearly free KA825 boards - I'd be
nice to bring this up to an 8350.
The disks are 3rd-party ESDI (1.2Gb each) drives on a 3rd-party ESDI-
to-SDI controller. Very nice. Beats an RA81 hands down. At the moment,
I'm running VMS 5.4 and plan to continue for some time (due to
compatibility needs for the COMBOARD stuff I used to write). I do have
a pair of RA70s I was thinking of putting on it as well.
So... the DEBNT itself fails self-test if there is nothing attached
to the AUI connector. If I attach a DEC loopback connector to the
AUI plug, ISTR I get the yellow LED telling me it passed. If I put
a 10BaseT transceiver on there, the TX light stays lit with no networking
drivers/software loaded.
First and foremost, I'm attempting to verify I put the cables on the
right places. I have 30-pin connector off one end of the AUI cable.
I have a 30-pin connector with one wire attached that seems to be a
jumper block of some kind. At the moment, they are attached to the
BI backplane at block "E", I think because that's what seemed to be
right from looking at where the Lance chip is on the DEBNT. If anyone
has installation instructions, particularly cabling instructions,
those would be very helpful.
Once I get the hardware happy, I'll need to move to software. Since
I want to stay at VMS 5.4, what are my TCP/IP options as a hobbyist?
The only other VAX I have set up with Ethernet is also running 5.4 -
a uVAX-II with a DEQNA. I do have VMS 6.1, but I'm not using it
at the moment.
Thanks for any DEBNT and VAXBI tips and hints. I have some docs, but not
everything. Mostly, I'm drawing on general VAX experience combined with
observation and experimentation. I know my way around the VAXBI bus, but
not around some of the peripherals.

I was up to my elbows in the 8200 last night. I think I've identified
the target pin on the DD11DK that is the destination of the damaged pin
in the first place - BB2 which is defined as a ground. This is odd because
on the paddle card, the signal is individually routed over pin 30 of JP2 and
is not tied to anything else on either end.
Having inspected the cable carefully, multiple times, I'm still scratching
my head as to how the damage could have happened in the first place. I
had notes written right on the Unibus cables where they stick onto the
back of the VAXBI - the notations match the docs (I have the DWBUA technical
manual with installation instructions). I can't even see how putting the
paddle card in backwards would have caused a massive problem. I'm afraid
to hook everything up and power it on again before I identify what was
wrong.
OTOH, I did drop the T1010 card in the VAX and look for its presence on
the bus. With the cables disconnected, the card fails self-test (Duh!)
but when I go to read the ident register of the DWBUA (E 20000000), I
get back FFFFFFFF, not the expected value (as documented in the manual).
Having written VMS VAXBI drivers in the past, I can say that this is not
good. The card "shows up" - the POST shows a "-0", so the VAXBIIC of
the DWBUA is detected, but it's exceedingly unhappy. I am suspecting
that the card is more fried than one chip. I'll keep working on it to
see if the card needs a rudimentary amount of attachment to the UNIBUS
to get far enough into its self-test to initialize the ident register,
but I'm not hopeful about it - I think it should show the world what
it is, even if it's unhappy.
Fortunately, I have docs for all of this. At this time, I suspect the
M9313 UET, the DD11DK, the cables and the T1010 card. I just have to narrow
down the list of suspects. I suppose I could drop the card in with the
chip at risk removed and a lead hanging out so I can monitor what's
happening on that pin. The pin itself happens to go to the outer-most
pad on the VAXBI bus, looking at the board, it's the farthest pad
>from the VAXBIIC on the solder side. It goes diagonally in more-or-less
a straight line to a pin of a DEC DC021C, 4 or 5, IIRC (it's not in front
of me here). Either that pin sources a whopping amount of current
>from the DC021 and it was shorted to ground by a bad cable or a problem
in the BA11, or somehow a very wrong voltage came from the BA11 into
that pin. It's the only way I can see how a trace can get cooked and
the chip melted at that pin.
Back to the basement...

Nothing comes up for the part number 40G1041. At least, I think it's the
part number-- it looks like all the other part numbers. Pretty sure it's on
topic too, at least the 82365s on the back are dated '92. Anyone know what
the settings are? It's got a 4-position DIP switch for `SLOT ADDR, `IRQ',
and `ROM ADDR', and also a slide-switch marked `BLK1 BLK0'. I wonder what
that does.
I hope I can put this thing to use--it's really pretty nice, at least to
look at. It's got little solenoids to physically lock the cards in the
slot. Only trouble (aside from not knowing what it's set for) is that it's
just a hair too wide to fit into the two computers I've tried it in so far.
Hope I can find something to put it in!

Sounds like it fits the IBM PS/2 E, machine type 9533.

Anyone interested in seeing where the money should be sent? Should be able
to have a bit of fun. I though there had been enough publicity on this one that
everyone would remember the Nigeria scam by now.
Also, do any of the police in Nigeria care? Can police in any other
country trace this sort of thing? Or do the police just say to toss
it and forget it?
Better have a well protected site - they may just be sending back a virus!
