I was told that Don Maslin can help me with boot disks for some old CP/M
computers. I need boot disks for the following:
Morrow Micro Decision MD 1
Epson QX-10
several different Kaypro models
I tried to make a boot disk for the Morrow using 22disk and the 'STDCPM22'
file at 'www.retroarchive.org'. 22disk did not have a file format for the
Morrow MD 1, so I used the format for the Morrow MD 2. (As far as I have
been able to find out, the MD1 had full height floppy disk drives and the
MD2 had half-height drives, but they were the same capacity). When I tried
to use the floppy to boot the computer, it would spin for about 15 seconds,
then the computer would reboot.
I was making the boot disk on a computer which had a 360K floppy drive.
Thanks!

After removing the magnetic disk I use denatured ethyl alcohol and a soft
lintless cotton cloth to wipe it down. Paper towns are too abrasive, use soft
cotton, preferably lintless. Work on top of a cotton cloth also.
If there is dirt or other abrasives I would rinse this off with water and do
the final drying with the alcohol wipe.
I have used a head cleaning diskette jacket as a holder for the truly floppy
disk at this point.
I do not think you can successfully dry out a wet jacket very well, better to

Well, in the Big Box of Token-Ring Stuff I received a few days ago, there
was one EISA TR adapter, a Compaq Netflex-2 ENET/TR. ENET as in Ethernet,
TR as in token-ring. That's right, this baby apparently can speak ethernet
*and* token-ring! I've been going over Comp^H^H^HHPs site for the last
half-hour, and the only thing I've found out about it is that a part number
is COMX142151, the TR side is an option that I presubably have installed (as
the card has a jumper block on the TR side and not the ENET side), and it
was avaliable on just about everything from the pro-whatever-500 through
the -4500. Does anyone know where I can find the .cfg file for this? Can
it speak ethernet and token-ring at the same time? Is there a manual for it
anywhere?
Thanks!

I had a small accident in my basement a couple of days ago and in
cleaning everything out I discovered an old box of 5.25 TRS-80/Heathkit
floppies with all my old stuff on them were damp with water. I let them
air dry overnight, but some of them still don't spin freely.
What can I do to recover these disks - I hate to lose them. What sort of
damage does water cause to floppies?
Thanks,

Hello,
Does anyone have a set of SMD drive cables that they would be willing
to part with? I am looking for something that is at least 8' long, or
maybe even a bit longer. They typically consist of a 60 pin twisted

I had an accident involving 2 liters of coke and two dozen of my prize 5
1/4" floppies. I carefully slit the top (away from the access hole) and
rinsed them in a sink of dishwater, then rinsed and let dry completely, then
slit new disks, remove the new media disk and put the old (now cleaned)
media into the new sleeve, and taped it with clear tape. Then immediately
copied the disks to good new disks...They worked like a champ and I
recovered everything....
Hope this helps

Dear List,
What is the concensus on disposal of 286 and 386sx
hardware -- should they be consigned to the bin, or
are there any folks out there collecting them? (or
needing spares?).
One is a Schneider 286 Tower PC (10Mhz), and the other
is a Philips P3345 (16Mhz).
Personally, I do not view either as being particularly
noteworth (other than, perhaps, for sentimental
reasons) .. but seems such a shame to turn them into
landfill :-)

Bummer! Well, dunno if this will be helpful to you or not, but we had a
zillion 3.5" floppies from 1984 (first Mac) and they got immersed in
water during Hurricane Andrew in 1992...they didn't work at all, so
figuring we had nothing to lose, I slit the labels, popped 'em apart,
and removed the disk itself, wiped down both surfaces with Q-tips and
rubbing alcohol. Then I took new floppies and disassembled them, tossed
the blank media, and put the old disk inside the case...taped back
together, and almost all of them worked well enough to recover the
data. The real issue seemed to be that the two paper pads swelled and
wrinkled, then dried, depositing lint on the disk surface and impeding
spin. The disks themselves seemed to weather the water fine.
(The Mac itself survived Andrew also -- I still have it. Only hurricane
damage was a couple dead keyswitches on the keyboard, I replaced those
and all's well -- 11 years later. :) If only the roof had been so
durable...)
Good luck...

I have one of these, but not complete. Its missing most of the little
stuff like chips, cards, cash. Some overlays are missing, and I am pretty
sure the rifle is long since destroyed.
I'm also not positive if the unit itself works or not. Its one of the
things on my list to install in my "retro" basement when I finally find a
house I can afford.

I was shuffling some of my collected VaxenStuff, and in the 4000 I found
a couple of CMD CDI-4000 DSSI to SCSI bridge cards..... A yahoo and

a supposed user's manual... :-{(
Does anyone know of a real (working) link to a manual?? Failing that,
does anyone know what jumper / ribbon cable does what?

Hey there! I hope this isn't bad form but I'm new to the list and just
wanted to put my collecting needs out there and ask a question or two.
Currently I'm partial to anything TRS-80, PCjr, or PC XT related. But
I'm also trying to fill in some gaps with Commodore , TI 99, and Apple
II(e).
Also, where do y'all find most of your stuff? There's always ebay, but
that's usually at a premium. I've thought about notifying some of the
local auction houses to keep an eye out.
Any input would be appreciated, and it's good to know that there are
folks out there who don't immediately think "samford and son" whenever
they see "obsolete" hardware!

The last two times I posted this, another person contacted
me either for help or to request the CDs. This will be the
last time for about 6 months unless more people reply.
In regard to the Freeware CDs for RSX-11 and RT-11
that Tim Shoppa originally produced:
I am in the middle of finishing a second (very small) batch
of CDs and could easily add a few additional copies.
I will be making all copies of the CD images from:
ftp://ftp.trailing-edge.com/pub/cd-images/http://www.classiccmp.org/PDP-11/RT-11/http://www.classiccmp.org/PDP-11/RSX-11/
Since not everyone has both a high speed internet connection
and a CD burner, I thought it would be helpful to make them
available. If you have both requirements and are using
Windows 98 SE / Nero Burning, I can help with the details
if you don't know how to burn a CD from an "Image File".
I have even been able to produce a label for each
CD that is close to the original label from Tim Shoppa,
although since they were scanned (THANK YOU
FOR THE HELP), they are not perfect.
They are available at $ 5 / $ 9 / $ 12 for 1 / 2 / 3 CDs.
In addition, I understand that Memorex Black CD-Rs have a
longer shelf life and are available at Business Depot. If anyone
wants those instead, add $ 1 for each CD that you are
requesting. Thus those amounts are $ 6 / $ 11 / $ 15
Please contact me directly for my snail mail address.
I picked up some Memorex Black CD-R blanks and started
on the copies for those who have already requested that a
Black CD-R be used.
Please include your mailing address!!!!!!!!!!!!!!!!!!!
In general, I will regard any funds you send as a gift so that if
anyone really can't afford the CDs, please state why that is so.
Outside of the US, probably about $ 2 should be sufficient
for extra postage. All amounts are in US dollars. Please ask
if you are not in the US. No point in converting twice.
Sincerely yours,

I have for sale a few Northern Telecom (yes, NT, not Nortel) Model NT6K90AC Displayphone, Date of Mfr. Nov 15 1984 (yeps, that makes them almost 19 years old, way ahead of their time). If you are interested, and know what this is for, do let me know. I think 50 USD for each is fairly reasonable. They are in very, very good working condition taken out of service a number of years ago, stored and finally sold off recently. I picked them up at a government auction, and they are being sold as-is. I know little to nothing about them, and am by no means an expert, you are more than I am...PS. I hope this is ok to offer these here for sale. I looked at the listing, and it seems this kind of device was WAY ahead of its time, so much so that NT didn't do much with them, but they are prized for collectors. I hope I can find a nice home for them.Best wishesTodd Nathan
The New Yahoo! Search - Faster. Easier. Bingo.
I would love to take the SWTP6809 system. I already have an SWTP6800 that I acquired recently.
Getting on 20 years ago I built a 6809 based computer from a series running in the UK magazine "Electronics & Computing Monthly", called the 77/68 system. This was based on the SWTP stuff but was marketed through a company called Stirling Microsystems in Baker Street, London. Does anyone else here remember that system? There's one reference to it on a Google search here: http://www.jakelod.demon.co.uk/7768.htm, although now even that link isn't working anymore. Was I the only person ever to build it?!!!
I never got it working, and I think my parents must have chucked it all out unfortunately, although I've still got all the docs including circuit diagram and hex dumps.

Subject: Seeking good home(s) for old hardware
Can anyone provide any suggestions, flippant or otherwise, as to where
I might seek new homes for some old kit that has been cluttering my
attic for many years? My wife is putting her foot down, and frankly I
am never going to do anything with it. I am paring down my collection
of old computers and peripherals to a few that I will actually use,
and trying to find people who will actually use the others.
So I need homes for:
* SWTPC 6809 computer. Main unit, disk unit inc. 8 1/2" Qume floppy
drive, Western digital harddisk controller but no HDD. VDU/terminal
(not working). Used to run Uniflex (but I don't have this, since the
hard disk crashed and there were no originals provided). I have all
the hardware and software manuals. I have seen this computer working
but it has been stored a long time.
* Remex paper tape reader/writer (works as far as I know, but I don't
have the cables for it).
* Diablo daisy wheel (have seen it working but about 17 years ago!)
It's a long shot, but somebody may be able to help. I can provide
more details if anyone is interested. Mail me at jpcc "at" bigfoot
"dot" com if you prefer. I am in the UK.
Is there anyone out there that has, or knows of anyone with microbee(s)
they want to sell/get rid of.
please mail me at vivid(a)australia.edu with ANY info.
Thanks.. any info would be helpful.

The sound generator chips that I recall TI making were the SN76477N,
SN76488N, and the SN94281. I believe TI also made some others, but those
were commonly available to hobbyist in the time period that is mentioned
above. I'm fairly sure Radio Shack at one time sold some of those
particular sound generator chips too.
I have the data sheet for the SN94281, but I'm not sure about the other
two. If it would be helpful, I can scan it.

Yes and yes, up to a point. They do use HP 88140 tapes (and may take

backups to restore the image to another model of drive. For that
matter, I'm not sure what the drive writes on them in the course of a
standalone backup or whether the drive will permit user-level read
access to the standalone backup media. I don't see any reason why it
wouldn't, except for notions about security, but then I'm pretty sure
these drives will write to some regions of the tape even if you've set
the write-protect knob to "protect" -- so I think they're too smart
for their own good.

Just saw this on comp.sys.cdc
Unfortunately, they may have waited too long for help :-<
Greetings:
Our computer museum, The Cybertheque Museum, has been preserving
important CDC computers and their software, manuals and spare
parts since 1971; we are currently in a major funding crisis and
there is jeopardy of the irretrievable loss (lien sale) of the
following machines (and more):
1. CDC 160 S/N 18 (handwired at Chippewa, overhanging desktop,
rising punch)
2. CDC 160A S/N 270
3. CDC 606A S/N 9 (non-corporate switches)
4. CDC 8092 Teleprogrammer S/N 24
5. Librascope General Precision LGP-30 vacuum tube computer S/N 254
6. Various IBM card unit record peripherals for the 160.
7. CDC 1604 Console (with typewriter and punch)
8. CDC 3200 Console and Typewriter Console and various 3200 frames.
9. CDC 6400 cabinet
10. large amount of 1604, 3000, 6000, 7000, Control Corp, DDI,
and peripheral logic cards
11. The entire FOCUS program library for the 160/160A
12. Much of the software library for the 1604
13. Much object and source for 6000 SCOPE
14. Experimental Operating Systems from Roseville and Rochester for
the 160A/8090
15. 1700 Software
16. The entire software library for the Roseville TFC/MTC 32bit mini-
computer.
And much much more.
Since a crisis precipitated by the unreasonable real-estate tax and
redevelopment policies of Anoka County, MN in 1991, we were denied
our musuem building and forced to store the above systems in storage
unit warehousing in the Twin Cities area. The rental agreement was
reasonable at the time but in the ensuing years the warehouse company
decided to breach the agreement and forced us to pay ever increasing
rent until it has become a major burden. The intent was to ready
new facilities in Northern Minnesota and move the collection; the
high rent at the warehouses and the high cost of transportation has
delayed the relocation effort.
We must pay $900.00 per month for the storage; we are attempting to
raise money to cover some past rent to avoid a lien sale on April
23. We are open to discussions to salvage the collection before the
sale and/or to partner with others and receive donations to support
the ongoing rental until relocation is possible.
Please help us avoid the sad loss of such important artifacts.

Will your surplus place let you plug it in before you take one? This might be
the best choice now that you know how to deal with the locks.
If you have it home, I would just make sure it is level, warm and plug it in.
Hmm, that's right, you live in Florida you don't have to make sure it is
warm.
I am going to wait till summer before trying to start the 3350s I have.
Good luck. I consider these Priams to be fairly sturdy drives.

At the urging on one of the other local collectors and against my better judgement, I went back and picked up the HP 7914 disk drive that was part of the HP 1000 system that I recently acquired. I think this is going to be a waste of time since I've never found one of these old drives that still worked. But I'm going to try this one and see what happens. Anyone have any suggestions about anything that I should check or do before I try to spin this drive up?

I recall back in the 1990-91 timeframe when VMS was first being
distributed on CD as well as tape, we got these plastic cases
that held the CDs, and each CD was in an RRD40 pincer caddy.
Which was fine for my lab because we actually had an RRD40
on hand... I'm not sure if the CONDIST started early enough
to be delivered the same way.
I used to have one of these VMS 5.x CD kits around here, but
it seems determined to remain hidden so I can't confirm.

Anyone know if the interface card for the PlusTek Spectra 1200 and 6000
sheet feed scanners is a SCSI card?
I have both of these scanners. On the back is a DB25 Male port. No power
input, so it pulls power from the connector. The manuals I have just
indicate that it uses an "Interface Card" that comes with the scanner.
Naturally I don't have the card or the cable.
I'm curious if it is a SCSI card as many older scanners used. I'm looking
to possibly bring one back to life to try using for archiving of old
manuals (the HP All-In-One I had set aside for the purpose I just found
out is a Print/Copy/Fax, no scanner).
If it uses a special custom card, either A: does anyone have one that
they want to give me (and the cable if it is something special as well),
or B: does anyone want the scanners? I don't know if either works as they
were given to me as is years ago and have never been used. I do have the
manuals for them, as well as one driver disk (but the drivers appear to
still be downloadable from PlusTek's web site).

Try places that carry old PC junk. This type of CD-ROM was used primarily in
1-4x CD-ROM's that were seen in PC's (the fastest I've seen is an 8x that I
put in my PDP-11/73). Of course you can also find this style CD-ROM in DEC,
Sun, and probably other manufacturer's equipment (I think Apple had one
drive of this style).
Actually your best place to look might be eBay, I'd imagine they're pretty
easy to find there.
Just be glad you don't have one of the drives that use the 'pincer' caddies!

Last call if anyone wants my Printronix or parts from it. The printer
supposedly has a fried transformer in the power supply. I know it does
not power up.
I have the complete printer, rolling stand, and at least one paper basket.

It goes in the dumpster Monday afternoon if someone doesn't speak up
first.

>Machines with 1.2M drives weigh less than machines with 360K drives?
No, no that doesn't work... my Leading Edge machines have 360K drives,
and they weigh less than my IBM AT's with 1.2M drives.
:-)
-chris
<http://www.mythtech.net>
I have been told (by an IT professional, take that for what it's worth)
that 5.25" 360K drives have the latch handle on the left side of the
drive, and the 1.2M drives have it on the right side. All the drives
I have in view right now, this is true.
Anybody have a notion of whether this is absolutely true in fact?
It sure would make sorting drives easier than trying them out on an
old peecee! (Which actually needs to be done anyways, to test for
functionality.)
Found this this morning. Full length 16 ISAcard for a PC. Marked "Arnet Smartport" "Made in USA" and "Copyright 1985 Arnet Corporation". It has a daughterboard marked "Arnet Smart Plus 4". The main board has two copper shielded 34 pin ribbon cables that extend out the back panel. Snybody know what this is?

Actually IIRC the HP 7914 has a Priam 15050 single platter(?) hard drive with
a 14 inch platter. The HP 7912 used the similar Priam 6650 drive.
These were used in many early computers from the late 70s to early 80s. Early
Xerox 8010 Stars had them so there may be some info on the drives on Al
Kossow's Site.
IIRC these auto head park (with a loud clunk) when powered off. There may be
drive &/or head locks too.
I am looking for information on starting up some Priam 3350s, 8 inch HD
drives. I have an Intel 330 (6 slot Multibus 1) and an Intel 380 (14 Slot
Multibus 1 with separate drive cabinet) that I want to fire up before I part
with them. Both these use Priam 3350s. Also looking for ideas on how to start
them safely. Last time I used them was about 1989. I did park the heads and
locked the drives for the intervening years.

Does anyone have documentation for the complete command codes of the Epson
Stylus Color 600 printer?
The command codes are apparently identical to those of the LQ-850, so a
manual for that printer will also do.
Any help would be greatly appreciated.
