Nop. There have been at least 2 major public releases
other than 1.25. 1.0 and 1.1. 1.0 was the first public
release for the IBM PC and 1.1 added new disk types.
1.1 and 1.25 are almost identical - 1.1 was the IBM
version, 1.25 the OEM version.
If you're searching old versions (maybe prior to 1.25)
you should look for things like Z-DOS (Zenith), 86-DOS
(back licensed MS-DOS to Seatle Computer products),
SB-86 (Lifeboat Associates) or COMPAQ-DOS (guess who :).
Maybe a bunch of other names I don't recall right
now, since MS licenced it to any 8088/8086 computer
manufacturer available.
DOS 1.x was still machine dependant, since the BIOS had
to met the hardware. DOS 2.0 and up added new disk types
and loadabel device driver.
With 2.0 Microsoft tried to establish their own trademark
MS-DOS as OS and scraped all OEM licences or at least tried
to cut of the different names. After 2.0 only IBM kept the
private name of PC DOS.

Well, the computer repair company I worked for used to do alot of LCD and
laptop repair. Alot of times the lines are either easy to fix problems w/
cables and little wire connectors, and other times they are just on their
way out ( i repaired servers and desktops so I never got to dabble :/ ) in
any case, a good place that does *VERY* reasonable LCD and laptop repair is
Matrix International, which i believe is www.matrixintl.com, or... I've
forgotten the phone #, but they are in Austin TX. they used to do flat rate
LCD repair for us for 125 a system.

IBM P/S 2, Model 50Z
On-Site Computer Systems box... Unit seems to have two hard
disk drives, that, on the outside, remind me of the old RD54
(I think) that used to be in the old DEC PRO-350's, two LPT
ports, and one serial port. Also a 5 3/4" floppy drive...
Anyone ever heard of these people, or know anything about their
stuff?
3 Monitors, one NEC, one Samsung, and one Tandy.
A Citizen MSP-20 printer..
Cost of this "rescue" US 20$, and the people even helped
load it into my car..

To date I've successfuly opened and fixed maxtor2190s and Micropolus 1325s
wit HDA difficulties. I've run a RD52 with the cover off as a demonstration
and I have somewhere a 16 year old st506 with a lexan topcover for viewing.
It all boils down to what was the failure and is it fixable. The latter
can be hard as platter assemblies and generally "glued and screwed" and
tend to be hard to get apart. Heads are small fine things easily broken.
If the media is scared it's a total as the metal will be everywhere and
some fo the metal like the head cantelever is steel so all that steel dust
is now in the magnet assembly for the positioner... Not impossible but
there is a certain amount of pick and choose in which one to fix.

It's an Apple IIc clone, and very similar to it. It has one Apple II
compatible slot on the left side. Laser was the only company which
actually made legal Apple II clones and withstood Apple's lawyers.

this machine is essentially an apple //c compatible. the keyboard sucks, but
has the same function as a //c. the machine also has an expansion slot on the
left to which an apple card can plug into, although it was not designed for
it. i once ran a disk controller card in it without problems. make sure you
get the power supply. ive been told the //c ps was equivalent though. the
machine supposedly was 99% apple compatible which was true since i never could

I was peeking into the Popular Science at the supermarket yesterday, and
I noticed a peculiar entry in "What's New": a computer shaped like a
black cube, the size of a NeXT cube, but balanced on one corner with
little feet supporting it. It's made of aluminum and is just a regular
PC. Next to it, it had an LCD panel and keyboard. The case was much
uglier than the NeXT, and I don't quite know the reason for making it a
cube - it doesn't support four motherboards or anything! Just thought
you people might be interested.

I've posted this before but the list occupants change so I'll see if I
can find a home again for it. Everytime I go to rework it to a CGA/EGA
cable I think that there's someone out there with a crap mono monitor on
a PCjr that would love to have an original PCJr Color Display. It's in
great shape and I don't have a Jr and haven't messed with one since
college a thousand years ago.
If anyone might be interested in negociating a fair trade of cash or PC
items that I can use in other machines drop me a note. PC Enterprises is
one of the few sources that still has "refurbished" PCJr Color Displays
and they want an outrageous $189 or so for one. I'd like to slap anyone
that would pay that in this stage of the Jr's...
Contact me direct if interested.
BTW....If anyone may be intertested in the Visual 102 with keyboard for
FREE (you pay the shipping) it's now LAST CALL before I strip the
goodies out of it and send it to computer and terminal heaven. Contact
me soon.

I have two box type units labeled as an HP9123D that appear to have two
3.5" type removable (floppy?) drives in each, with an HPIB bus connector
and a cable with a 5 pin DIN on the end. It also states that it's for
use only with the HP45849A. They're both complete and like new but I
have no equipment to test them with. I know HP stuff is expensive even
when used and these aren't all that old by their looks and styling so
they should make some HP owner very happy. I have no use for them but
yet I would hate to dismantle them or dump them.
Anyone know what these are exactly and would anyone be interested in the
wo of them, maybe a trade or something?
Email direct if interested in them.

Every so often, someone asks how many computers I have, and I always find
it hard to give a straight answer. It depends whether you count half a
dozen 68000 boards as 1 + spares, or 6 -- I only have two keyboards and one
PSU rigged up for them -- or none, since I haven't got the orignal case or
PSU. Or the PDP-11s; I have several spare CPUs and other boards, but only
a few cabinets.
This is roughly what's running/runnable:
Acorn Archimedes A440, serial no 614 + Arm3 processor a a lot of extras
Acorn Archimedes A310, serial no 2.
BBC Microcomputer Model B (about 2.5 of these)
BBC Microcomputer Model B-plus
Torch Z80 Card x 2
Acorn Z80
Acorn 6502
Acorn Electron
Acorn Atom
Apple ][+
Apple //e
Apple Mac Plus x 2
Sharp MZ80K
Atari MegaST
Exidy Sorcerer
Commodore PET 2001-8K
Commodore 128 (US version)
Commodore VIC-20
Amiga 500 (well, half of one, anyway)
homebrew Z8 SBC
Sinclair ZX81
Sinclair Spectrum
Sinclair Spectrum 48K
Sinclair QL (plus a dead one)
Sparcstation 1+
Silicon Graphics Indy R4600SC
XT-compatible
AT-compatible
486SX-25
486DX2-66
386sx-20 portable
286 Compaq LTE
11/23 x 2
11/03 x 2
11/34
11/24 (only the board set, though)
11/73 x 2
?PDP-11/83
microVax II
uMicro 2000 (a 68000 system and a lot of spare boards)
Sage II (another 68000)
Cambridge Z88
Psion Organiser
AgendA
and, of course, a whole lot of peripherals.

The MSD drives were perhaps the first 1541 clones, though I am not positive of
that.
They were not complete compatible, so copy protected software probably would
not work.

I have not yet found an operating manual for the RK07's in the group of
stuff I got. I want to check them out and think I recall that they can be
powered up and maybe heads loaded while not attached to the host. True? If
so, anything I should know? What to look for if anything not correct?
Also, the previous owner left packs *in* two of the drives :( . One
probably is an all-important boot disk for the 1/34A as he told me he had
booted it up the day before I picked them up. Well, I'm not too happy with
this as there may be a risk that the disk got damaged during moving and
transport. I can take the black sheet metal cover off the drives and check
that the heads are retracted. How do I get the disk out as the disk cover
seems to be locked? Will powering up and a certain keypress unlock the disk
cover without the heads moving onto the platter?
I'll need to do the same to the RL01's and RL02's to sort through them as
to functionality.
Thanks yet again for the help.
Regards, Chris

Minix is not awful with recognizing hard drives, it doesn't claim to support
all of them.
If you want you can put dos on the m70 and then install the version ported
to load and run as under dos as a virtual disk. That works on everything
that is running dos. While not fancy it's enough to play with and to keep
it small (its a test version) the sources are not on it though they can be
copied easily enough.

Serves 'em $#%%^@& right. Emulex's support was (is) of the most suckful sort.
I would never recommend any of their products to anybody (forget about getting

Are you sure about that first one? I tried to install it on a PS/2 Model
70 and it didn't recognize the hard drive. In general, i've found Minix
to be simply awful with recognizing hard drives.

It's unix... depending on who you ask yes or no. ;)
Compared to DOS it's better, it's a real multiprocessing OS.
As implmented for 386 and larger it lacks VM making some BIG unix apps
like Xwindows unlikely but for text apps it screams. There is a version
called minix-vm and from what I've hears runs well.
MINIX plug, it's value is, sources are on line and it runs on XTs and
PS/2s and the whole install with sorces fits in something like 40mb.
It's limits are no VM, support for COM1/2 only and the book/CDrom cost
about 70$. It is available on the net, install kits and sources.
I installed it on the Dell and it was textbook easy (compared to dos!)
and considering the machine is a 386sx/16 it's really quite fast.

Are file formats different between RSX-11M and RT-11? If I get one of the
PDPs up and running I need to sort out the 40-50 disk packs that should be
a mixture of RT and RSX.
There's a boot pack labeled for the 11/24 but it will be a surprise as to
which OS boots. I think there's an RK07 pack for the 11/34A and I
understand from the previous owner that RSX had been the OS running on it.
If there's some version dependancy involved, the RSX boot disk pack is
probably 4.x and if the 11/24 pack is RT, it is *possibly* v3.x.
There's an even bigger batch of 9-track tapes. ~75 or so hangin' on the
tape rack. But, I think most of those could be backup tapes or development
files from Moog Hydropoint machine tools (Moog made computer controlled
machine tools) according to what I see in the rather cryptic contents of
the labels. I gotta get the rack w/TS03 and TS11 subsystem lashed up to the
11/24 or 11/34A (whichever I get running first) to check them out.
Will an RL01 pack be readable in an RL02 drive?
Thanks again,
Chris

I have been taking inventory of the boot ROMS on the M9312 modules in
several of the PDP-11's in the great haul. In the pile of documents there
is an older manual for the 9312 (1978 copyright, purple/maroon cover.)
Fine. I was able to determine what's what re this subject and their
respective boot devices (RL01, RK07, etc.)
However, I need help identifying this one found in my 11/34A: 767A9. Need
the charts/boot device type for this one which show the same type data as I
see in my older 9312 manual.
Also, in the 11/24 I found a different E20 ROM (the console/diagnostic
ROM). Its number is 774F1. The number found on all the other 9312 E20 ROMS
is 248F1.
Now, is this 774F1 specific to the 11/24 only? Or, is it specific to any
Unibus -11/xx which has no programmers console attached to the front of the
machine (the /24 just has a few switches on the front panel)?
The 11/34A I'm keeping and the other two 11/34x BA11's either have, or have
evidence of once having, a programmer's console attached which could be a
hint that the 248F1 is simply the E20 ROM just for 11/34x machines w/prgmrs
console.
Thanks for helping me sort out this detail.
BTW, that URL Kees Stravers posted here per my query has the most VAX
11/730 info I have found yet. It has some great info to help me get going
on my uVAX II which also came to me in that haul. Again:
http://vaxarchive.ml.org . Thanks Kees. I'm still looking for more 11/730
info everybody (so is Kees).
Thanks for the help.

NS how old this box is, but it looks about as old as my uVax3100s...
Customer has an PH-UX machine, HP 715/100, and it's playing paperweight.
Powers on, makes hard-disk noises when the boot switch is pressed, but
doesn't talk to the console. When you push the power-off button, it makes
more noise and shuts off. Something's working, but I have no console.
Any ideas?
This happened after someone downed it the wrong way.
As I have little experience with HPs, I thought it appropriate to ask a higher
authority :)

Anyone possibly have a manual for one of these? I'd like to buy one, pay

Hmm, is that the p/n for a Touchscreen II aka HP150 with 12-inch
display? I know those have the 5-pin DIN connector inside and the
9123 would be contemporary, can't remember if the ones we had at

didn't IBM release a version of DOS before that? Similarly with IBM DOS

The earliest version of Microsoft Windows was 1.0, which had a certain
resemblance to the DOS Shell. There were very few programs for Windows
1.0 and 2.0, and programs written under Windows 3.1 won't run on earlier
version, neither will Windows 3.1 run older software. 3.0 can run 2.0
programs. Microsoft bought QDOS (Quick & Dirty Operating System) in Beta
form from Seattle Computer, Ltd. the night before they had to give IBM
an operating system for the upcoming PC, for $50,000. The first DOS was
1.0, which had no support for hard disks as its greatest flaw. 2.0 had
hard drive support. In general, most modern programs require DOS 3.1 or
higher due to some functions DOS provides. I'm not too familiar with all
of the exact revision history. Is there a page anywhere with this info?

Hi
I was talking to a few friends and we wore wondering what the earliest
versions of micro soft's dos and windows was.
The earlies version of windows I have herd of is windows 2.0, I also think
there was a windows whith out a version number.
The earlies version of dos I herd about was dos1.1 or some thing like that,
it has been a while so I'am a byt fogggy on it.
I am currious about the software because I wonder how well or pore it

There was a 'special edition' of the Newton 120 in clear case.
A friend of mine has one - I'm still looking - there are only

800-100 DM (USD 500+). Still on my wishlist.

On all 68LC040 Macs you just need to exchange it with
an 68040 to get the MathCo. Just check the frequency.
But using a 636 for NetBSD isn't a good idea - any
486-PC will give the same or better performance - but
while using Mac OS 8 the 63x are just fine machines.
Gruss
H.
P.S.: don't forget the memory update - the 63x Macs
can use 36 or 52 MB of Mem, depending on the mobo
revision. If you have 1 SIMM slot, add a 32MB module,
if there are two slots, use a 16 MB modul in the outhermost
and a 32 in the innermost slot.

no idea what they're from, but I'd like to know. If you think you can

Hi Dug
Sory I havent been able to reply sooner, I got burried under in email,
like a thousand messages. It takes me a while to go threw.
Yah the power failure is a problem, I would write the note and save it to
disk on a flopy, so I would have lots of notes to go threw. I didn't loose
any data this way, but am not sure what the power failure did to the system
files.
It always booted in to the wordprosessor so I don't think power outage
effected the software.
It took a few days of thinking to figure out how to repair the broken
pin on the CPU, since I couldn't solder something that small.
I didn't think it would work, and was trying to find a new CPU for it,
well, it worked so I was spaired that.
Also, I got a new piece of equiptment, it's a little box about five
inches square and about one and some inches thick. It has a cable whith a
DB 9 feemale conecter on the end of it.
It's a Double talk synthasiser, Thought I'de sneek that in on you. I have
been bissy whith configuring software on a notebook computer to make it
talk.
You can hear what it sounds like if you have a wave player, there are
some wave files and other info about the doubletalk at:
www.rcsys.com
The cool thing about the doubletalk is the text to speech conversion is
done by the doubletalk itself, so it doesn't use the computer's CPU to do
that.
Some of the text to speech software takes about 300K of conventional
memory, this is a painfully slow way to use synthasisers whith computers.
Another part of making the computer talk iss a screen reader program, this
is what I was configuring , or trying to configure.
What the screen reader does is it sends what is on the screen to the
synthasiser to be spoken. The screenreader also does more things, but that
is the basic thing it does.
If you want to experiment whith a screen reader and don't have a
synthasiser, I found one that uses the computer speaker to speek threw, I
like this one because it installs itself and is easy to use, it's called
seekline screen reader.
Seekline has some drawbacks mainly the conventional memory usage mentioned
abuv, another problem is seekline doesn't recognise non ascii characters on
the screen, I don't know what these are since I can't see them. This is a
newsence when you are in some setup programs, because when seekline sais
press nonascii to exit, it is unknown what key to press.
Aside from that seekline is a great little program.
If you wnat to try it out it lives at:
http://world.std.com/~speechfb
The downloadable Seekline screen reader is shareware, one file about a meg
or more called sl.exe
works in dos.
I have been trying to get people to try some of the screenreaders to get
some feed back on what they think, I am not doing a servay or any thing like
that, I am just curious about what people think.
So if you have some extra time let me know what you think., I just thought
of some thing, maybe you could install it on the Wang computer, it just
might talk threw the computer speeker.
I didn't know about seekline when I had the wang but if it worked in it I
would have kept the wang.
Befor you install seekline run the installation on a computer whith a
monotor, so you can see what the menu choises are, seekline doesn't modify
config.sys or autoexec.bat what seekline does is it writes a start.bat file
in the seekline directory it writes to the hard drive.
I forgot the 5.25 flopy problem, oh well, it was just a thought.
Well, write me soon!

Look at the air flow and realize that dust on the platter is suffering from

Like I said in an earlier mail, all these drive have internal filters that

I have about 20 - 30 computers, about 15 monitors, and documentation for
about half of the units. Mostly 8-bit systems and some Macs. I've got a
pretty meager collection in comparison to most of you guys. :-) The
pickings just aren't as good here in South-Central PA.

A glove box is trivial to build. I'd use a 25 CFM blower and a small hepa
filter and the box could be made with LEXAN (clear plastic) glued with RTV
and cleaned well. the front would be a curtain of 6mil poly with velcro
holding it to the edges. Holes would be provided to allow reaching in with
plastic gloved hands. The hole to not have to be air tight around the
gloves and the positive airflow in in the box would insure air flows out.
Hint: filter is on the output side of the blower forcing air into the box
and the outflow is through a coarse filter to limit outflow.

devices and magnetics were not well understood as yet.

Because if you making 500-1000 drives a day tossing 10-20 for damage due
to someone sneezing is far to costly. Also they have to insure they are
clean. But the level of clean needed is low. A hair net, nylon dust free
gloves, no facial hair and a dustmask over the nose and mouth would
eminimate 90% of human sources. Also not putting finger prints or other
debries on the disk is a must as rag wiping is already far to filthy.
there is care and there is paranoia. For example did you know that ESD
is damaging to magnetic media? If you deliver a hard spark to the plated
media you may pit it some or at least remagnetize a small area, disaster
for servo tracks.
FYI/note: Why do ALL drives spin up then load the heads? It's to allow
the airflow from the spinning media to establish the clean airflow inside
the drive. Also any dust on the active portion of the media spins off the
media and is then captured in a filter.

for the most part that's close, I do have some that have cost me in the
hundreds (200to400) per machine. Lately I have been getting alot of free
items from people that find out I collect old machines, a old Lawyer friend
called my last week and asked her to pick up some items he no longer
wanted. I have not seem any of it yet, but on my next trip to Texas I get
to see then and I will give an update on these new finds here. I get about
one call a week here and I have not put an ad in the paper yet. So as
always tell everyone you meet that you are a collector and see what happens
it cost nothing to spread the word this way. John

I don't mean in general production. I know I've seen 100's, 110's, and

2000's. There's an _excellent_ web site devoted to rare Newtons. I lost

When Apple discontinued the Newton a few months back there was a small
protest held by Newton users and developers at Apple headquarters. At
this Apple past around wooden Newtons for the people to look at it. I
don't know if any have been released outside the company, though it
wouldn't suprise me if some disappeared during the rally.

Sure! I certainly have quite an aura of dandruff around me. Once, I
opened up a 44MB hard drive because it wouldn't work (still don't know
what's wrong). When I was closing it, I noticed that it had dust on the
platter. After wiping it many times, blowing on it, etc. I found it was
impossible to get it really clean.

I have no experience with this, but I am willing to bet that it's the
ribbon cables that go from the circuit board to the LCD. I've known them
to cause this. First, check that the glue or tape that holds them to the
board didn't undo itself. If not, I have no idea how to replace them,
since they are attached right onto the LCD panel.

As I've said before, I think that getting the battery to work correctly
will solve your sad mac problems. I was able to temporarily recharge the
battery by taking an old power cable, plugging it in, and touching the
cables to the battery terminals. It blew the surge protector a couple of
times, but eventually, I was able to power up the mac. However, this
will eventually wear off and the mac will cease to work again. When this
happened to me, I decided to rebuild the battery, so I took it apart and
left it on my shelf for a few months while the mac ran off two AC
adapters. Then I decided I won't rebuild the battery after all because
it would cost $30 to buy the cells, so I put it back together and
reinserted it into the mac. The two AC adapters were still plugged in.
After several weeks of sitting on this intensive overvoltaged charge
cycle (during which the machine still worked), the battery is as
reliable as it should be. I haven't tested it in fear that it might not
recharge too well again, but the portable runs for 15 minutes at least
w/o wall adapters.

I have an Apple ][ disk drive in a clear (orange) plastic case in front of
me right now. The plastic itself just wraps around the top and two sides,
with the back and bottom being grey plastic. It is a standard size
isk ][ drive, badged on the back Apple Computer Ltd, Holly Hill Industrial
Estate, Cork, Ireland just like the two other regular Disk ][ drives I have.
But the plastic itself has no markings on it, so it MAY have been put on by
an earlier owner.

Why is that? Who ever heard of a battery charger for a laptop being

similar amperage to the internal battery slot, I should be good to go.

I have seen vertical lines on LCD's, one or more pixels wide. These were
swapped in a repair shop, so thought there was some ESD damage to the
drivers on the LCD module. The lines were still there when the cables,
controller were switched. The rest of the display still worked OK. It may
have bad contacts to the LCD electrodes, as well, this could give the same
effect, although open contacts may leave the addressed line "blank" not black.

Am I nuts or is it possible to use 8 and 16 bit ISA cards in an EISA
slot? This is my first hardware level adventure with an EISA machine and
right now it has EISA controllers and open slots, that I would love to
put certain ISA cards (sound for one) into but while I'm reasonably
sure, I don't want to risk blowing anything up. I've been under the
understanding that EISA was backward compatible with ISA.

I know this was brought up before, but I never heard a clear answer:
What's the difference between a C64 and a C64c, apart from the C128-ish
case design on the C64c?
I heard rumors that it had better sound chips or something, and all the
Commodore dealers (not many left) that I have seen advertise the C64c for
about 20% more than the standard C64.

Microcom makes modems. Maybe other datacomm stuff too. What kinds
of connectors are on the back plate?
I have a full-length ISA 8-bit card here with a 68000 on it --
it's a Telebit modem. I'm not sure whether it's a T1000 or a

Speaking of curious cards: I just picked up 5 stripped down Dell 433p
machines. Nothing in them except motherboard, 486-dx33 processor, and riser
card. BUT... In two or three I found the following card. I didn't look hard
enough at the numbers, but I can pretty much describe it:
The card has one dsub shell, 9-pin on the back, there's a machined aluminum
chip on the card, marked IBM, and there's an ODD and EVEN ROM set. My first
guess was mono graphics cards (VGA is built-in to MB) but I got to
thinking: Did IBM ever make a network card with this type of connector on
it? All I know is twisted pair, coax, and have seen token ring stuff before
but not worked with it. What does it sound like to you guys?

I don't believe they were prototypes; more of souvenir-type deals, I
believe. I could see paying $200, $300 is more than I'd spend for most
any 'classic' computer.

I beleive just about all the Newton Messagepads were done in clear
cases and they're really not _that_ uncommon. You'll see them for sale
every 6 months or so if you read the Newton Classifieds. Most recently,
I saw a non-working MP 100 go for $100 (my offer was the second highest
at $40). From what I understand, there were even some Newton's done in
wooden cases, though I'm not sure if these were operational. Prototypes
of the eMate were also done in a wide variety of colors.
I've seen and heard of lots of different Macs being done in clear
plastic. In addition to the Portable you mentioned, several members of
the Mac II family, as well as the LC. I also vaguely remember something
about a green Mac Classic. Anybody?

I can't find any mention of it either. And of course, if it doesn't
start up, it's awfully hard to run the diagnostic software. I never did
understand that...
I'd say the HD is the least of your problems. After all, you can always
run the system of the floppy and there is an external SCSI port. There's
a guy in Virgina who does a lot of work with Mac Portables; he has
adapters so that you can use normal SCSI HD's internally for $30. If
anybody's really interested I can probably find his name and email
somewhere.

Hello, all:
I made another trip to Temple University yesterday to rummage through
their storehouse of old computers and documentation. I hate to post a list,
but I don't have a working web site yet, and I want everyone to know what I
have in case someone needs something.
Here it goes...
1. Mac Portable (no HD, bad batteries)
2. Many Unibus and Q-Bus boards
3. Odd DEC single-board computer. 10" x 7" labeled DEC 54-16489, Has two
84-pin PLCC chips
with the LSI LIA 0433 and 0434 marks. Has a DB25, DB15, and DB9.
Recognizable chips
include 8051, FD1796, CDP 6402 (RCA), and D7201C (NEC) Can anyone
identify this?
4. Three Motorola 68K educational computers. Has 32k RAM, 68K, 6850,
14411 chips and a
proto area. Also has two EPROMs. Any guess?
5. Three KIM-1s!! (There are one or two more left, too). Two are
MOS-labeled, one is *brand new* from
Conversational Voice Terminal Corp. of Chicago. Need data on this
one. The MOS-labeled ones
have 1976-dated ceramic chips.
6. A S-100 backplane from Forethought Products. Has 8 slots, some glue
and regulator chips.
7. Lots of documentation. A sampling...
-- Intel: MCS80/85 User Guide (1983), Memory Handbook (83), Embedded
Controller Book (88), Component Data Book (80; looks to be full-line), OEM
Boards (87), 8080/85 Assembly Language Programming Manual, Applications
Note --implementing a floppy system (1981).
-- DEC: Logic handbook (77), Microcomputer Microprocessors (78)
-- Motorola: MC68020 User Man., MEK6800 Guide, 6809 Assembly
Language, 6800 Pgmr. Ref. Manual.
-- Full documentation set for the Rockwell AIM-65 computer (user
guide, BASIC language, Programmers Manual, Hardware Manual, Monitor Program
Listing).
-- Textbooks on microprocessors by Tocci & Laskowski, and Camp, Smay
& Triska
8. Old magazines. The guy who ran the CS department before the guy I know
saved everything. Byte's going back to 1978 (too many to get this trip),
Datamation, others that I never heard of. But, the jewel is that I came
*this* close to getting the Altair issue of Popular Electronics.
Unfortulately, this guy only had as far back as 1/76. Articles include:
Cosmal Elf construction articles, SOL construction, build a Scientific
Calculator, music with the 8080, TV Typewriter, SpeechLab, Computer Club
listings, a personal microwave communications system, various
Classic-relevant product reviews and buyer's guides.
9. DEC paper tapes: PDP-11 power fail, LPS11 tests, General Test Program,
RK05 dynamic test, RK11 utilities, exerciser, static tests.
10. Complete print sets for the following: PDP 11/34A (two copies,
complete), FP11, H960 cabinet, KSI-11, DLV-11, DL-11, H9720, ET-LSI-11,
LSI-11 power supply, MS11, PC11, LPS11, MR11, M873, KD11F, RK05 (regular, F,
and J).
My plan is to scan the articles, and have an on-line database hanging
off of a web site. I also want to implement a bar code system for my
goodies. That'll take a while, though.
Anyway, thanks for the bandwidth.

I'm having problems with the Mac Portable that I got.
Besides the hard drive and batteries being shot and the screen having a
small defect in it, I keep getting a Sad Mac code. It's code 0000000F with a
sub code of 00007FFF. I can't find a reference to the $0F code in any Sad
Mac code listings that I have (they skip over it, going from $0E to $10). I
get the code after inserting a known-working diskette. I've tried 400k disks
and 800k disks with the same results. I haven't tried a 1.44m disk yet,
since I don't have a recent Mac to create one. I've tried a 1.44m disk
created by HVFExplorer, but I get the "bad disk" message.
Also, there's a 4-position DIP switch on the mobo. What's this for? Any
ideas on the Sad Mac code?

the one I had had a ten meg winchester hard drive, that was some drive, I
think it was made of cast iron well, the case at any rate. It also had a
glass like cover ocovering up the iners of the harddrive.
The two 5.52 flopys wore 180 K and conected to the mother board.
It does slide out of the sleeve quite nicely, the two cards that are
conected togather are lan and mem ory combination, I think, when I removed
them I had less memory.
I found out why it wouldn't boot, it was a pin on the c p u didn't make it
in the hole, when some one tryed to plug it in, straitening the pin cracked
it off, ****! I thought about it for some time and used a peese of coper
wire to fix it, first I incerted the wire into the hole whear the broken pin
would have been once the chip was pluged in, I don't remember how I was able
to locate the hole, I don't have to tell you how tiny they are, the chip
still had a bit id the broken pin sticking out of the side of it, not enough
to solder , but enough to make a tite contact whith the coper wire, after
the chip was plugged back in I trimed itso it didn't stick up a half inchbut
just a little over the top of the chip.
It worked!
I can't remember if it booted in a wordprosesser or a menu, I think it was
a word prosessor.
I seem to remember some thing funy about the program was you couldn't quit
it , it would not let you I think it just rebooted, unless you had a flopy
in drive A:.
The not so funy thing about the monotor is the power and data cords
coming out of it both had the same plug on the end of them, and pluging the
data plug in to the power socket on the vidio card was a hasard.
Since they wore bothe the same kind of plug I tied a twist tie around the
power plug just to let me know whitch was whitch, just incase I got the ich
to use the monoter when I was writting stuff in the word prosesser.
Oh well, It was still is a great machine albeit huge!

Not entirely true. ESD does permanent damage to the device even if it
doesn't die. ALL (that I know of) drives have an internal air filter to
pick up any dust that may appear so if the media is not damaged the air will
be cleaned and reliability should be nominal (excludes the reason for first
opening it). I have several drives I've had to open all running and all
apparently living longer than average!
Allison
I have the feeling this is the early version, because mine is the later
backlit one, which has no dip switches. The sad mac code could very
easily be due to a power problem. It will sadmac if there isn't enough
power. Note that running off the portable AC adapter is _not_ enough.
You need an additional .5 amps, whereever you get it.

Well, the cpu on this mac is socketed, i *could* just pop it out- in fact it

There's also the program 'SoftFPU' (or something like that) which
emulates an FPU. Slow, but it works.

My first thought for the 2 BNCs would be a Stereo SID (sound chip)
modification. That is a popular hardware mod that adds a second SID
sythesizer chip to the 64 so you can have 2 channel, 6 voice stereo. There
are a few music writer programs and players and a game or two that support it.
Usually the mod has RCA type jacks though...
Pretty cool if you like the 64 sound output (which is really good for an 8-bitter).

Hi,
Great day today, I found:
Zenith ZT1, aparently it is a phone terminal and has the manual to connect
to compuserve. Is it also useable as a computer? I have the manual but it's
burried at the moment.
HP 97 brand new in the box and it seems to be working fine. I'm charging the
battery right now to check it. Standard pack and business decision pack plus
a bag of programming sheets
Text editing, math, Visicalc Plus and owners manuals for the HP85
HP thermal printer with HPIL interface (HP 82162A) what is that for? is it
tfor the HP 75?
HP82901M Dual 5.25" flexible disk drive with HPIB interface. I believe it is
for the HP85
Box of five blank tapes for the HP 85
HP110 laptop computer (8086 or so) with MS-DOS 2.0 in ROM With manual and
lotus 123 complete.
2 HP9114 3.5" disk drives for the HP 110 with manual charger and HPIL cables
HP 2225A Think jet with HPIL interface for the HP 110
On the sad side I had to pass on an Original MAC M0001, a MAC SE, SE/30 the
HP 85 (already have 2) a box of thermal paper for the HP85, a commodore
calculator and loads of softwares for the HP 85 and 150 series and a bunch
of unrecognized boxes (probably compatibles) I'm really thinking about going
back tomorrow If I can get the OK from above:)

As I told Tony Duell a day or two ago, I would list the modules residing in
my 11/730. Point being to compare machines for completeness/options and to
get feedback from list members to learn more about what both of us have
exactly.
I would like to fully restore this machine to it's original completeness
although not necessarily its original options/configuration. I'm missing
front/rear doors, some hardware, a few modules, misc. items and the
all-important TU58 tape which has the bootup microcode(!). Hopefully a
fellow who responded privately can find some docs and cabinet parts that he
might have which will help for sure. I'll be looking for the rest though.
The main problem I have found with the module list is that there are no
references in the Field Guide for these particular 11/730 modules. Maybe
because the Guide was for *only* Q-bus and UNIBUS modules and these don't
fall into that classification *or* simply the info for these modules was
not at hand when the FG was put together. I'm working on that now with a
fellow who emailed me in reference to a more up-to-date FG. Any input from
the group is welcome of course.
Here's the list of modules, in order of slot number, in the 730 as I
received it:
1. empty
2. empty
3. empty
4. M8390 (-B?)
5. empty
6. M8391 MCT
7. M8394
8. M8750-CP
9. M8750-CP
10. M8396
11. M8396
12. G7273
13. G7273
14. empty
No expansion backplane is installed presently. I think it may have been
taken out as there is reference on the module list printed on the CPU cover
which shows a 9-slot DD11-DK Unibus Expander Backplane installed in the
left side of the crate.
I have not dug into either of the BA11 crates I have in the pile yet but
would the 9-slot expansion backplanes in these actually be the DD11-DK? Is
"DD11-DK" marked anywhere on them?
The Ethernet cable is also hanging loose in the crate. Either a single
board Ethernet I/F was in slot 14 or the 2-board DEUNA or equivalent was in
two slotts of the DD11-DK expansion.
For the sake of comparison with what the factory-original module compliment
says, I will note in quotes ("") what's on the CPU cover label:
1. "Not used"
2. "M8389 FPA (Option)" (must be a floating pt. adaptor)
3. "Not used"
4. "M8390 DAP"
5. "Not used"
6. "M8391-YA or M8391 MCT"
7. "M8394 WCS"
8. "MS730-CA"
9. "MS730-CA"
10. "G7273/Memory"
11. "G7273/Not for Unibus Option"
12. "G7273/Not for Unibus Option"
13. "G7273/Unibus Option"
14. "M9202" (and) "G7273/Unibus Option"
<end 11/730-A CPU listing>
<begin DD11-DK backplane listing>
1. "M9202" (bridge from slot 14, above) "G727"
2. "G727"
| | (all 9 slots have G727's listed)
| |
9. "M9302" (and) "G727"
Hmmm, if I either have a DD11-DK in a BA11 or something around here or if I
could find one amongst list members, then I could hang Unibus options off
this machine :) Cool!
Anyway, my guess is that I don't have too far to go to restore this box
with help from folks here. Tony would benefit too regarding his own 730.
And yes, I understand it is a true dog as to performance. But it was
mentioned by Allison correctly that at least this is a "real iron" VAX
which will fit in a room and power requirements are low enough to be rather
tolerable. Recall I have a space problem here. I saw a picture and weight
(1k+ lbs) of a 11/780. The wife would shoot me if I had one to keep out of
that truckload <g>.
Thanks again for the help. Regards,

In looking at the RK07 and RL01/02 drives that I have from the Great Haul,
the connectors and cables look rather similar.
In the 11/34A I am keeping, there is a five-board set which is the RK611
controller. The previous owner had RK07's hung off this controller. I want
to use at least one RL02 in the system as most of the disk packs with the
important s/w are RL01/02. Anybody know if the RLs will work off the RK611
controller? (This is one of those dumb newbie questions!)
If it won't work, anybody have a spare RL11 controller module (M7762)
they'll let go? There's a heap of RL's (7) in the stuff I got but the only
machine in the whole pile that has an RL11 is the 11/24 which is not going
to be kept by me.
What would the cable run limits be on either the RL11 or RK611 systems?
As someone had told me a bit earlier about SDI systems, only ODD number of
cables must be used. Any such limitation here?
Thanks for your input!

I finally went back to check on that "Wang PC-002" I asked about earlier.
It was a bit more scratched up, but it hadn't moved an inch in the past
two and a half(?) weeks.
I managed to locate its keyboard, as well as the keyboard for an aparently
keyboardless Tandy 1000TX that was in another part of the building, so I
decided to drag the Wang machine home.
NOT an easy job. It was about a mile to the nearest subway station, with
lots of broken escalators up and down once I got into the system. And I
was carrying a large book bag full of stuff I have to look over for work.
By the time the bus dropped me off near home, we were in the middle of a
thunder storm. So I left the computer on top of someone's gate post (wide
brick thing with flat cement top) under some trees near the bus stop, and
made a run for home (about a half-mile).
I went back with the car as soon as I got home.
Anyway, it sure is a curious beast. And HUGE, to my eyes. It's not quite
as big as I reported before, but it's BIG. The closest offhand and
possibly innacurate comparison I could make is to a friend's MicroVax, but
I don't know what kind of MicroVax that is.
If I sit it vertically (a position the box looks very comfortable in), it
measures about 15" high, by 6.5" wide, by 23" long.
It has two floppy drives mounted in the front: one half-height 5.25"
drive, and one full-hieght 5.25" drive.
In the back, I can see the backs of various cards. One of them has the
connector for the keyboard (4-pin DIN) as well as one serial and one
parallel port, so it must be the motherboard. Beside that (or above,
depending on orientation) is a board with a sticker reading "PM032-B 512K
Memory Expansion". Next to that, is what appears to be an empty slot, and
then there is what appears to be some kind of networking card. It has two
coaxial cable connectors and a toggle switch. There is another card
beside (or above) that, with no ports or labels, but I can see chips
through the air holes. Beside (or above) the mystery card is a board with
a label reading "PM101 IBM Mono Emulation". It has an 8-pin DIN connector
and a 5-pin DIN connector, which I would guess are for monitor and PC
keyboard(?).
Does anyone know the pinouts of the various ports, or anything else about
this machine? Will it read PC disks or do I need to boot it up with some
wacky Wang-format disk? Does the machine require some kind of terminal,
or will a monitor connect into the back of the IBM Emulation board and let
me see what's going on?
The sticker on the side (top) of the machine says it's a PC-002, but the
sticker on the back says it's a PC-P002.
The keyboard has a lot of word processing functions on it.
Anyway, I haven't opened it up yet, or done anything with it but look at
it. Disassembly looks like it might be difficult, because I have to slip
the innards through the full length metal sleeve. I won't be up to that
until my arms recover. I've even got bruises and some kind of blood
blisters or something, from carrying that thing. :/
I probably won't have time to play with it today as I promised to install
NetBSD 1.3.2 and some UNIX software on my Amiga 3000 instead of coming to
work. (And look at the time. :) )
