Just stumbled onto a message posted on Nov 7, 2002, in which you mentioned
having some UYK-20 machines.
Should you have any left, or locate any more of the -20's or -44's, please
add me to the list. Being a true diehard collecter, I
might also consider coming and picking up something bigger: UYK-7, Univac
1218, CP-642, etc. Just depends on the price and the timing.
Thanks,

We were buying it from Staples and Office Depot up until recently. As of
when we stopped buying it, they were still carrying it (we just upgraded
our system and moved to printing to a laser printer... MUCH cheaper).
I am pretty sure Staples still sells it. Its kind of pricey. IIRC, it was
about $50 or $60 for a box.

Well I have my 9134A connected to an HP-87 and when the system boots
it recognizes the hard disk automatically, so that you can just type
a CAT commend and see the directory listing.
One question, I assume that you have set the two address switches
on the back to *different* addresses (e.g. HP-IB addr 0 for the hard
disk and addr 1 for the floppy). So if you try to do a CAT on the
floppy address, do you still get a timeout?

Hi,
I've got a IUP201a programmer with a Fast27K module which works fine. I'm
seeking docs on them.
I can upload hex files from a PC via serial port but I know that it is
possible to download from programmer to PC via serial port. Widely it is
possible to command programmer from host but I need command language.

Dear Mr. Arnold:
I found your name through a Google search for TIL-308 numeric displays. You
were in some kind of web discussion concerning replacing the TIL-307/307
displays with TIL-308 displays. You mentioned that you had a small quantity
of TIL-308s. We are looking for a few of these displays. Are they still
available and, if so, what is the price?

Hello,
I am having trouble interfacing an HP 9134 HDD to my HP 85. I have connected
other drives without difficulty such as the 9121D so I believe the computer
is set up properly.
I recently picked up a 9134A HD. It apparently emulates a 9895A 8" flexible
drive and 3 slaves each with 1.15MB capacity.
I set the HP-IB address to zero on the HD and typed MASS STORAGE is ":D700".
I then typed CAT and Initialize and keep getting a "Timeout". Also if I turn
the 85 on with the HD connected and running and type CAT the HD does not
respond as my 9121 would without typing a mass storage is command.
Can I assume the drive is bad or am I using the wrong syntax. The drive
spins up nicely, and the light comes on but I get that error message and the
disk access light does not come on.
I hate to toss this drive into the dumpster if it is functional.
Thank you for your thoughts.
Bob H
Hi folks,
I have an HP 9133 HDD that I'm going to have to re-format (for an HP based
measuring system).
The drive already has quite a lot of software on it that it seems a shame to
destroy.
I've stuck a bus analyser on the drive and had a quick look at the data
passing back and forth between a controller and it. I think that I can
control the drive OK (using cs80 protocol) from a PC with HPIB controller
card - i.e. I can identify the drive, check block sizes and pull data off or
write data to the drive.
It strikes me that an application that enables the information on a cs/80
drive to be pulled onto a PC, backed-up on another format (e.g. CD ROM) and
then written back to the cs80 drive would be useful - does such an
application already exist?
With the data clocks off the drive, I'm having a few problems working out
the actual format that HP use to record files on the disk.
It looks as though the first block on the disk (block 0) contains
information about the volume label, number of blocks available, number of
blocks allocated etc. (and I assume the length of the catalog).
The next few blocks seem to contain the catalog information itself - file
names, start locations lengths, file types etc.
Does anyone have access to details of the format that HP use to store files
on cs80 protocol disks/tapes?
(I already have a document 'cs/80 instruction set' dated March 1983 that has
proved invaluable in understanding the messages between the controller and
disk drive.)
Any help much appreciated.
Cheers
Peter Brown

Hi
The only problem here is something I saw done ( and
admitted to ) in shareware. The product was release to
shareware with a known bug. In order to get it fixed,
simply pay for the support/upgrade. I chose to delete
the original and not use either.
I had a couple of shareware programs that I released.
They were used by many hundreds of people. I only had
4 people send me the $5. I'm not complaining. Actually
I'm happy that so many found them useful. I'll have to
admit that most were college students so they have a good
excuse.
I've also used several shareware programs without sending
any money in so I can't complain about others. There were
a couple that I did send money in for and used quite a bit.
My only complaint is with abandonware. When the code is
no longer relevant, why hang onto it as though it were
of some value. I can see that one could make a point that
there might be something in the source that was of value
but the application is different.

Your continued attempt to justify your actions (posting private messages to a

If Sellam should "attack" and/or "harass" someone other than yourself, is that

I am not at all sure what you are suggesting here, but I *am* sure that I don't
like the sound of it. Since you do not have the power to banish Sellam or
anyone else from this list, and since such a banishment would still not prevent
Sellam or anyone else from sending private email messages, the above-quoted

If this is so, then why have you not asked for help in clear and simple

Hi
I just thought I'd share with you a few of my finds this week (maybe
someone will be able to shed a little light on one or two items?)
Sinclair Spectrum+ (nice condition in its original box) complete with
data cassette, joystick, games and thermal printer. I've already had
this up and running.
Dick Smith VZ-200 (again good condition) complete with 16kb memory
expansion (taking it to a heady 24kb), twin joystick adaptor. No power
supply with this but I've found out it takes 10V 800mA so that
shouldn't be too hard to rig up. Apparently these were sold in
Australia between 1983 and 1989, the VZ-200 being the first of the
model range. It uses the Z80 processor. (For those that don't know Dick
Smith is a Radio Shack style electronics outlet - he used to use the
catchy but rather self depreciating slogan "The Electronic Dick" )
IBM 122-key keyboard - this is the clicky type board with 24 function
buttons across the top and a group of preset functions to the left of
the main qwerty board. It has an 8 pin RJ45 style plug (rather than the
4 pin versions I've seen on Digital and Wyse keyboards). I don't know
where this comes from or what it was originally hooked up to.
Commodore PC10-III (this is the small case version) very clean
condition, came with the keyboard but no monitor. It powers up without
a problem.
Canon A-200 (that is the model stated on the back) This powers up fine
but the inbuilt graphics card does not like my mono monitor (in fact my
monitor doesn't like most cards, I must get around to changing it). It
has twin 5.25" floppies with a rather neat eject system that requires
you to push the button to lock the disk in and also to eject it (well,
I thought it was neat anyway). There is no hard disk but it came with a
boot floppy of a really cut down version of DOS 2.11 and a word
processing programme. I don't have a keyboard or anything else for that
matter with this. I can't find any information on the web about this
computer, it appears to have an 8086 or 8088 chip - I haven't
dismantled it all yet. Anyone know about this one?
Advanced Electronic Applications PAKRATT model PK-64 radio modem.
This is for the Commodore 64, SX64 and C128 (in C64 emulation mode). It
came with the manual, power adaptor and cables. In the blurb it states
that you can send and receive Morse, Baudot, ASCII, Amtor and AX.25
V2.0 (or below - but to receive morse you need the HFM-64 module). I
haven't tested this and don't have a C64 or Ham radio... it was just
one of those strange add-ons that would have bugged me if I'd let it
pass.
A couple of 2400 and 9600 modems and a box full of cards that I haven't
gone through yet.
Not a bad week in all.

The 9134A will work just fine with a HP85. It's the same as a 9135A
without the
5.25" floppy drive that the 9135A has. I've used a 9135A with both the HP85/87
family machines and with a HP9835B.

I believe those commands are for a 9826 or something else. On the HP85,
the 9134A/9135A drives emulate four 9895 8" floppy drives (approximately
1.2 Mbytes
each). If the unit address switches are set for 0, the individual logical
drive
units are ":D700", ":D701", "D702", and "D703" on the HP85.

I had much the same trouble with the hard drive in my 9135A when I got it.
It appears that the drive mechanism got "sticky" during a long period of
storage.
Much of the other stuff I got from the same lot as the 9135A was
rusty. Anyhow,
with some encouragement from list member Vassilis, I opened up the case,
unscrewed the hard drive (I think it's an ST-506) from the mounting
hardware and
set it on it's side, still hooked up, and was able to eventually get the disk
to initialize. It took a number of tries before I could get all four
partitions to
initialize, but once I got them all going, it worked fine.
I would try MASS STORAGE IS ":D700" and then INITIALIZE. If that doesn't work,
then try the same thing with ":D701", then ":D702", then ":D703". I wouldn't
give up unless you've tried it multiple times, alternating between partitions.
If you do decide to open up the case, you can see an arm on the side of the
drive that is supposed to move - it moves about 90 degrees going from the :D700
partition to the :D701 partition.
Once I got it working on the HP85 I tried it using my 9835B with Mass Storage
ROM, but I had to re-initialize the partitions I wanted to use with the
9835B because
they weren't compatible with the HP85 (too bad, I'd hoped to be able to
transfer data that way). Right now I have two partitions in HP85 format
and two in
9835 format.
At least Bob got the hard drive in his 9134A. I bought a second one that was
listed on eBay that ended later the same day as his, and when it arrived I
found that
the unit had been stripped and there was no hard drive inside :-(
Anybody have a spare ST-506???
Hope this helps,
Alex

Subject: Old Computer Books - what to do?
I'm about to do a Major Purge of my library. Part of that library is a
collection of old microcomputer books (catalog not yet available -
I'll post a pointer when it becomes available), which I kept around
for historical purposes. We're talking, Apple II; the original TRS-80,
and a big basket of random Bytes and Amiga magazines. Possibly even a
Creative Computing or two.
Since I'm never going to start a proper historical computer library,
I'd like to offer these books to interested parties. Not looking for
money or even recognition* here, just space on my bookshelves and Less
Stuff to Manage.
It was suggested elsewhere that I try here. Also, ebay and half.com have
already been mentiioned as possibilities, but I'm after the shelf space
not the money.
Any ideas? And, yes, interested individuals may apply.

Ok, what OS does it run? It says Intel Inside, but has an ADB Mac Mouse

but that still wouldn't use an ADB mouse).
Humm... NeXTStep maybe, using a Mac mouse as a replacement... they used
ADB on some model NeXT boxes, didn't they? Color is right for a NeXT Cube.

I have been invited to write a paper about the work being done

the individual collectors and the valuable work they are doing.
If you are in europe and collect/preserve computer
hardware/software/documentation I would appreciate a short
description of what you do, how big your collection is and anything
else you might like to mention.
I will probably highlight the contributions for just a few of you
but mention all of you. Please let me know if you would be willing
to be be an in depth subject which will entail an email interview.
Mention also if you would prefer to remain anonymous.
Finally, if you know of any other individuals working in the field
who are not subscribed to this list I would be interested in hearing

All contributors will receive a copy of the paper when it is

Take a look at the 12992-90001_loaderRomsApr86.pdf doc on Al's site. It has
details of the operation of the various HP 1000 loader ROMs, including
source code listings.
There is a separate ROM, p/n 12992-80007 12992E, which is specifically for
booting from the 9885 flexible disk. I'm not sure what interface is used to
the 9885 for that loader ROM.
ROM p/n 12992-80002 12992B is for MAC 7905/7920 drives, 13175A/B interface.
ROM p/n 12992-80004 12992H is for HP-IB 7920H/7925H/9895 drives, 12821A
interface.
If you remove the memory cards from the front card cage of the 1000E CPU you
should be able to see the loader ROMs and if you can read the p/n labels you
should be able to reference those back to the loader ROM doc to see exactly
what you have.

Hi Patrick
Reread my post. That is just about all it does. It does
have to initialize the port and that takes more than about
half the code. The loop that loads the memory is quite short.
The com port on the H89 is a 8250 and so needs a bunch of stuff
setup. To load a value into the port I/O takes 3 to 4 bytes,
regardless of how it is done. I suspect I can strip a little
but I doubt I can take out more than about 10%.
One thing I haven't tried is to use the Z80 I/O instructions
and have a table of things to output in sequence. This might be
shorter.
Anyway, I've made it so that I can optimize it more after
I get the rest of the functionality of the main code.
There is a small amount of extra because I've not used a fixed
load address or fixed size. I could shorten it a little and
keep it flexable by only writing the load address. One would
write the bytes backwards from there. At some point, the
JMP instructions address would be over written by my new load code.
The address of the high byte would be the same, just the
low byte part of the address would change, directing the
code to the newly loaded code. This would simplify the load
loop since no count needs to be maintained ( a trick I learned
form my Nicolet 1080's bootstrap ).
I'll make another pass at the code and publish what I have.
Others can then look at it for optimizations.

Is anyone here familar with these drives? I was checking some HP 1000s today and making particular note of what boot roms they contained. One of them had a label that said that it had a boot rom for the "7905/20 disk". I checked my references and found that these drives are supposed to use the Amigo/MAC protocall. I know that a lot of the older HP floppy drives (9885, 82901/902, 9121, etc) also use the Amigo prototcall. I'm wondering if that means that this 1000 can boot from one of those floppy drives. How compatible is the 7905/7920 Amigo protocall and the Amigo protocall that's used for the floppy drives?

I'm looking for two items to complete my omnibot 2000. I need the remote
control and the tray. Also the cardboard base would be nice to have. If
anyone has these items to sell or trade let me know off line. Thanks
Hi
I've started looking at how to make a H89 disk
transfer program that would allow one to make images
of the hard sectored disk into a DOS file. I've
had my H89 powered up and thought I'd pass on one
of the first problems I came across ( other than
one of the tantalums popping ). The belts on the
floppy drives have all stretched. Only about half
of my floppies would read. Since I don't have the
original full height drive, the drives I do have
had no adjustment for belt tension( they were ALPS
single sided drives, half height ). I had to file the
motor mount holes to get the drives to work well with the
pile of disk I have. Anyway, this is something to
watch for in the older drives.
Now, onto the more useful stuff. I've written some
bootstrap code that allows me to pass a program
into the H89 from a serial port. The code to do this
take a reasonable amount of space because of the need
to initialize the serial port. It currently takes
about 40H+ of code to enter ( in octal for Heath monitor ).
I might find some code in the ROMs that does this
part for me. This is a little long but there is not much
I can do about it. I am using the LP serial port of the H89
since it runs with a 1:1 wiring of a PC serial port ;)
The idea is that the first 4 bytes will contain
the address and count to load. The rest will be
the actual code. When it finishes the counted bytes,
it will automatically switch to the down loaded code.
This next code is expected to perform the functions of
format, disk image write and disk image read.
This will be used as the next level of bootstrapping.
I've got notes on all of the entry points to control
the H17 disk controller so I can do the various disk
operations. There is one problem I have now and that
is that the HDOS disk all have a thing called 'Volume
Number'. I expect that this was so that one could avoid
trashing other disk ( HDOS uses a mount/dismount system ).
The difficulty is that the first track is always volume
0 and the others are the particular volume number selected
for that disk. In order to read or write, one needs to
know the volume number for that disk. This is encoded on
the disk, similar to things like sector number and
track number. I haven't figured out how HDOS knows
what volume the disk is by looking at the first track.
I suppose it is someplace there. I suspect that
I may want to format the disk as I write the image so
that I can pass the volume number along. I'm not sure
if it is a good idea or not to keep the original
volume number. One might want to have new volume numbers
for each disk in their collection.
Still, I am making progress. Hopefully, this will
make sending and archiving HDOS disk easier. Any
suggestions on things I might want to add?

I am still being harrassed once again by Sellam.

Here is the text of his latest message...

Message 4:
The next time you send me a message I will report you
to the FBI for harassment and violating my civil
rights. You have called me an "Islamic Idiot" one

This is hate speech!
I am forwarding your messages to colleagues at the
ACLU and will pursue the matter legally if you
continue to send me your vitriolic hate
speech.
-----------------------------------------------------
I look forward to speaking to representatives of the
ACLU and FBI and presenting factual data of this list
user's continual hate and harrassment of me.
I'm sure there are several other list members who have
been harrassed by Sellam who would like to do likewise
(Contact me off the list if you'd like to do that).
I'd like the fantasies and harrassment to stop.
I have NEVER attacked Sellam over his religious
beliefs, and never would.
I have commented on Nastiness of Radical Islamics in
Afghanistan, Iraq, Iran, and other Middle Eastern
Countries. There lies the hate and intolerance.
But, I would plead guilty to being intolerant of
intolerance... LOL!
I'd much rather be dicussing some cool Classic
Computers...
The first weekend of May is the Trenton Computer
Festival (oddly held in Edison, New Jersey rather than
Trenton...). I'm looking forward to the Flea Market,
as I do every year.
Though sadly, each year the flea is dominated more and
more by PC's and less by cool classic computers.
I'm still hoping to get some Amiga Equipment, and a
TRS-80 Model I/III/4 for my collection. And possibly
anything for my Atari ST. But, there wasn't much there
last year. Mostly because I think the price for a Flea
Booth is too expensive for most people to sell the few
things they have.
It's a shame Ken Gore bought the rights for this show

made it less special and smaller in recent years.

The claim I called him an "Islamic Idiot" is totally
fictional. I used the term in a reply to message #2,
but was referring to people in the Radical Islamic

I predicted that would happen, and then got attacked
on and off the list by Sellam. Who somehow takes the
actions of other people of the Islamic faith
personally. In that people who criticizing them are
also criticizing him...
I just want the list to know how nasty and awful

And to give those of you who have written to me about
him off-list some more data for your files..
I am currently reporting him to his ISP for

Hi, I've found this
http://www.classiccmp.org/pipermail/cctech/2002-July/000553.html
searching for technical specs about the expansion ports of the PPC640.
In it you write "I have both the (software) technical manual and the service
manual."
Can you please look at the manuals, for the pinout of expansion ports A anc B?
My interest is about this statement:
"2) The PPC has an expansion bus which can be turned into normal
PC-compatible (8 bit) slots, so you can have an external display adapter"
The expansion bus is the ISA-8bit bus? Can I use it (rewiring it) for connect
a ISA card?
TIA, and sorry for my English. ^_^;

Hi
I think this show why we should keep both political
and religious comments out of our text and even our
signature lines. This group is really intend to be
a classic computer list. There are plenty of other
news groups and mail list that one can go out and
pick fights in.
I know that most people feel strongly about things.
It is good that they voice their opinions. It is just
that this is not the place.

Can't they?
Eons ago, when I owned a 65 T-Bird and was rebuilding it (a failed
project), I was told by a Ford Dealer that Ford can make ANY part for the
car if I request it. However it was going to cost a bundle as they had to
retool to make the parts. (The conversation was specifically revolving
around body panels and interior body parts... so engine and other
mechanical parts may not be included... I didn't clarify as I wasn't able
to afford used parts much less factory new).

Subject: 3.5" floppy drive in IBM XT?
> I picked up an old IBM XT today and it has a 3.5" floppy drive in
it (and it works!) Anybody ever heard of this? The drive has
it's own controller card and both it and the drive appear to be IBM
parts. )I haven't pulled everything apart to be sure.) FWIW the
computer also has a FH 5 1/4" floppy drive and a HH 5 1/4" 10 Mb hard
drive with a Seagate logo on the front of it. Anybody know if
this is an original XT hard drive or a replacement drive? It's been so
long since I've seen an original XT with the 10 Mb drive that
I don't remember much about it.
>
> Joe
I have a highly original late production XT, with the 640k system board,
720k hh floppy, 360k hh floppy, and full height IBM 20mb hard drive.
Interesting features include a Y cable to power both floppy drives from
the PSU connector (Y cable has black wires, and a cloth tag with IBM
part number 6480173). Also, the 720k drive has a plain blue eject
button. The 3.5" drives from the PS/2 series were labelled 1.44m or
2.88m as appropriate. The 360k drive has an asterisk on it, just like
on the optional AT 360k drive. Apparently the IBM convention for 5.25"
drives was that if it was a full height floppy, drive then it was 360k,
if it was a half height drive it was assumed to be 1.2M, unless it had
an asterisk, then it was 360k.
Mueller's book says that the 640k system board, XT 20M hd, half height
360k drive, and 720k drive were introduced in April, 1986.
Hope this helps solve the mystery....

It's nothing spectacular...
I have several IBM Model 76's sitting around my office (in storage) and I
thought I would try to replace the couple of remaining dumb terminals that
are all dying a slow death. I found a couple of these 3270 cards in an old
box a couple of years ago so I built a PC DOS 5.0/IBM PC3270 disk image on
one of the PCs. I built two and they still work beautifully ! I would have
built more but I could find no more cards and there wasn't much of a
demand. These are very sturdy machines (The IBM 76 and 77 Models) and I
would love to put more of them back in service. I admit I have a
sentimental attachment to them and have on several occasions had to make
excuses to keep others from tossing them.
So it's not critical... but if I can accomplish this I will be quite happy.
Peace to you as well.

Hi again...been awhile!
I got hold of the remains of a computer my dad built (with the help of
us kids, college age at the time) about 1980 or so. It's a 6809 S-100
bus system, with a microdasys MDA-6809A processor board, and a Solid
State Music VB1B video interface board. It also uses a Jameco JE610
ASCII keyboard.
The computer was stored in a shed where rats got in, and chewed away all
the wires connecing the cpu board to the case keyboard connector. So, I
need to figure out how to wire it back up. I also need to build a power
supply, although I might be able to use a bench supply I borrowed from
my brother...but it only provides 2 amps per side (dual supply, 0-30vdc).
Any scans of microdasys or SSM data shemetatics would be incredibly
helpful...but if you have links to sites with S-100 bus info, that would
also be a help.
I'm on digest mode, so expect delays...
Thanks!

They have accidentally activated CloseView, a control panel designed to
magnify the screen for people with vision problems.
To deactivate it, type Command-Option-O (hold the command key, that's the
cloverleaf, apple key, the option key, and the letter O all at the same
time).
To permanantly disable it, remove the CloseView icon from the Control
Panels folder and reboot the Mac.

Does anyone remember what the last update to System 7.5.x was? I'm in the process of getting my old PowerBook 540c (purchased used a few years ago to replace the 520c I wore out) setup to use as a 'typewriter', and noticed that I've got it running System 7.5.3.

Also listed a NEW unassembled Heathkit kit on there if anyone is intersted.

>Pirating is not something that should be condoned on this list.
I don't want to start a battle, so I'm not going to comment beyond this
email...
but... shouldn't "pirating" be something that IS condoned on this list?
At least under the idea of "abandonware". After all, without some degree
of software piracy, it is highly unlikely that a good chunk of the
hardware this list is interested in would have any useful software
available to it.
I very much support the idea of abondonware, and I would think that idea
is very much in this list's interest. However, it is in many cases still
piracy.

I took Doug's advice and called Tom Fischer who took over IMSAI's
operations when they went bankrupt.
The number of IMSAI's produced is as follows:
"According to a July 2002 e-mail from the IMSAI 8080 creator Joe Killian,
"I remember passing the 17,000 mark. I believe it never went past 20,000"
[between December of 1975 and September 1979]. Fischer-Freitas Company
produced another 2100+ machines between November 1979 and June 1986.
These machines can be identified by the Fischer-Freitas Company back panel
label."
This is right on the front page of imsai.net. More detailed information
can be found here:
http://www.imsai.net/history/imsai_history/imsai_pre_history.htm
These numbers are not broken down by front panel vs. turnkey system, so
it's still not readily known what the split was in terms of those counts.
IMSAI also sold a number of other machines. Here's a nice summary (still
being edited by Tom so some inaccuracies exist):

Found another HP 1000! Third one in three weeks. I think this one is a keeper. Got ALL the cables including the AC power cables, the interface panel, the CPU (2113E with option 065) and 1 MW of memory, boot loader ROMs for HP 264x terminal, CS-80 hard drives and HP 79xx disk drives, plenty of interface cards and a HP 12979 I/O Expander chassis. Best of all, this one was untampered with so everything was there and where it was suppsoed to be and I was able to mark where all the cables, etc all went to. The only thing that I've found wrong with it so far is two broken switches on the front panel from where they kicked it off the truck! It had a 7914 hard drive attached but I left it behind. I've never found one worth taking home. Pictures at <http://home.cfl.rr.com/rigdon14/hp1000/>.
