(A copy of this message has also been posted to the following newsgroups:
alt.folklore.computers)
OK, I have a few small(1/2 ton...) problems...
I broke my floppy drive! What size belt(IBM PN 2305616) does the 4965
drive use? And what material is the front cover? Seems that the cover for
the floppy drive uses molded tabs instead of those nice metal snaps. Has
anyone ever tried adding those snaps? I might do that... But meanwhile, I
either need a replacement cover or glue it together. Would normal
superglue work? OK, on to the floppy drive... Seems that after 15-20
years, floppy drives(among other things) like to break down. This time the
belt was rather brittle, and it snapped when I tried to remove it. I'm
expecting the same thing when I dig around in the hard drives.
OK, on to the next question... I have a total of five hard drives(one 4963
and four 4967), and one of the 4967's was setup as the primary IPL drive.
Problem is I don't know which one it is and have no way of figuring that
out(at least until I get everything else running right). I have two
floppies labeled as IPL... There is a set of two disks, the first says
"EDL Compile System, Insert in Drive 1 and IPL" and the other says "EDL
Compile System, Insert in Drive 2". What exactly are they? And the other
disk just says "IPL" with nothing else on the label. And then there is the
possibility that they are blank disks...
BTW, I'm working on a page for my Series/1 on my Tripod web site, it
should be up by the end of the week(assuming I can find my QuickCam by
then).
TIA

Rich, you don't say what flavour of PDP-11 you've got, but I have vague
memories of a '44. Certainly your description of behaviour sounds like
the '44 console program (which runs on an Intel microprocessor somewhere
in there.
If this is the case, I think Tony's description may be incomplete. The
'44 has a lever switch on the front panel marked something like HALT -
RUN - BOOT. You can try booting by toggling this to the BOOT position
and releasing it. Otherwise leave it in the RUN position and type:
B DK0
I suppose I'd better check this in the manual when I get home tonight -
If I'm wrong, Tony will never let me live it down...

<Err, 'PDP11' covers a whole lot of machines from something like an SBC2
<in a BA11-V (about the size off 2 modern notebooks stacked on top of ea
<other) to a PDP11/70 in a number of 6' racks. There's no 'average'
<machine IMHO
No to mention the PDT series and PRO350/380 series also a s100 board by
marinechip systems.
<There's a whole lot of OS's. Among them are :
<RT11 (single user, a little like CP/M)
RT-11 had four monitors, SJ/single job, FB/forground background,
XM/extended memory and a BM/batch monitor. Later versions (v5.5 or so)
have networking hooks for DECnet, lat and other services.
I run RT-11 on a:
BDV-11 (11/23A)
BA11S (11/23B)
BA11N (J11)
PDT11/130
Mongo (a dual by 12 slot rack with 11/23A, 1mb ram, DLV11j,
BDV11b rom(boot), H780 power)
<RSX-11 (many varients - the forerunner of VMS in many ways)
RSX-11 was the forerunner of VMS. It's realtime capable, multitasking
and can support timsharing as well. DECnet was supported for either
DDCMP or Eithernet networking.
POS
POS was a single user version of RSX-11 with a GUI interface for the
PRO300 series. It supported a Phone management system, large
format videodisk and DECnet via serial or Eithernet.
<DOS-11 (one user at a time, single tasking?)
<Tripos (Cambidge University's locally-written portable OS)
<Fuzzball (An OS with TCP/IP networking, using many utilities from RT11
<TSX-11 (multi-user OS built on top of RT11)
<Unix (certainly v5, v6, v7 and some BSD's ran on PDP11's)
V7 was supported on the MicroPDP-11 using the J11 (has I&D space) cpu.
<Xenix ? (I've heard rumours of a PDP11 port)
There was also Venix (I have that on a pro350).
<UCSD p-system
Learned Pascal using that on an H-11 varient.
<RSTS/E (never used it, so can't say what it's like)
Resource sharing, timesharing looks like rsx, rt or basic depending on
the monitor running. I have RSTS on DU0: of my system and RT-11 on DU1:
Later versions of RSTS support DECnet networking.
<XXDP+ (diagnostic OS)
Realllllly slooowwww.
Also CTS-300/rt-11 Commercial operating system supporting DIbol which
was a sorta cobol.
DSM-11 a database system with MUMPS as the language
There as CAPS a cassette OS for the TU60 dectape.
Micropower Pascal (host is RT) target is OS less and can be what ever
the applications is.
<There were also some stand-alone programs that didn't need an OS,
<including an assembler and Basic from DEC (which loaded from paper tape
<FIG-forth, a couple of other Forths, etc.
IOX, not an OS but an IO excutive for building custom systems.
Allison
Loads more docs from Knox! Vax/PDP stuff, and some PDP-8 printsets.
I also saw DEC SYSTEM-TEN on some books. A CP/M diskset (Not sure what for), a few magtapes, and some module.
What's an M840? I thought is was the CR04 card, am I wrong?
I have't looked thru it all yet, more later.

Hi -- perhaps you can help me! I am looking for a working Mattel
Electronic Football game. Do you have any advice for me?
I'm sending this from work, but would appreciate it if you could respond
to my home e-mail -- farrell7(a)swbell.net
Thanks and happy new year!
Well, the electrician came today to upgrade my service to 200A, and laughed
when I told him that the thing that prompted me was that I got this "large,
old computer." He couldn't believe that a "residential" computer draws 30A
startup and 15A running. The sound of it amazes me, too.
Anyway, I hooked a terminal up to it and lo-and-behold, a prompt. Now, I've
never owned a PDP-11, so be gentile, here. How do I get it to run a command
shell? I have installed two RK05 drives, the 0: drive has a {supposedly
good} RT-11. Upon boot, I get the following on the terminal:
000000 170002 170002 165360
$
I'm assuming that the "$" prompt is the monitor prompt. It seems to only
accept two-letter commands before performing an auto-carriage-return. The
"165360" is also on the front panel display.
Any clues would be appreciated. I'd like to get this thing running by
the time I get back to work on 1/5. Happy New Year to all!

It seems the PDP-11 is the favorite machine on this group... I have never seen
one, so could someone tell me a few things.
a)Year
b)original price for average package
c)does it have an OS? What is it like?
d)what can the thing do?

While cleaning up piles of boxes over the holidays, I've unearthed a bunch
of PDP-11 documentation. Most of it is RSX stuff from the 80s, but I've
also got two copies of the 1978 RSX-11M System Logic Manual. Some of the
materials are from various training classes I took during my career with
Digital.
Also uncovered are assorted DECUS publications from the 80s.
As a certified pack rat, I hate to throw this stuff away, so I'm offering
it to anyone who will pay the postage from the Chicago area to wherever in
the world you are.
If you're interested in any or all of this stash, send me e-mail before
January 9th. I'll see what I can do about inventorying the 10 cubic feet
of assorted binders between now and then.

i have recently been given an old Zenith laptop model ZFL-181-92. batteries
discharged or dead. no power supply. i would like information if anyone
can help me on what type of power supply to use. the label on the bottom
of the systems says: DC 12 V, Plug-in power supply Model 150-272.
i'm hoping someone out there has one of these puppies and can tell me the
power rating and polarity spec's (the power jack is not marked as to which
pole is positive). i haven't cracked the case open yet but am interested
in more information on this system if anyone can educate me. i think this
is an old 8088-based box? it has no hard drive but does have dual ("pop
up") 3-1/2" drives (someone has written "720" on them so they're presumably
720 k drives). i wonder if this will run a generic DOS?
any help appreciated. tx.

I just had the most wonderful bit of luck, and have been offered the
Kaypro II, 4 and 10 in the one hit, for almost nothing. Anyway, the
person offering them was curious (and now so am I) regarding the
existance of the Kaypro 16. Was there indeed such a system, and how sis
it differ from the others? And did Kaypro make anything else?
Thanks heaps,
Adam.
Hello.

Gang -
I've saved 2 Apollo 3500's from the dumpster
at work. Unfortunately, I know nothing about
Domain OS, nor was I able to save the books,
software or tapes.
I did however save the complete units,
including the 14" color monitors, keyboards
and 1 of the mice. The one unit I've opened
up is configured with 24M ram, and the
340MB ESDI drive.
Since there seems to be no good port of
any other operating system, I'm looking for
a good home for them. I take best offers
for the next couple of weeks with one
caveat - you must come to St. Louis to pick
them up. I am not in a good position to
freight ship these units, and don't have the
time to build a suitable crate/pallet.
Please reply by email, since I don't get to
read the digest as quick as I would like.
Thanks!

Many months ago, I saw an old tower at a thrift store for $20. I did not take
it, and now wonder what I missed.
It was a tall tower case, kind of like a PS/2. I think it was a WYSE. It had
two LED displays, one said something like 8, the other ".2". There was a 51/4"
floppy drive, and I could see an MFM -like hard drive through the half-open
case, mounted at the very top. It worked, but all it had on the grey sheet
metal back was a power connector, four 15-pin terminal ports and 4 ethernet-
like connectors.
What did I miss?

Dear All,
I offered this a few weeks ago but didn't get any replies. Appologies
if someone did answer but it didn't get through :-(.
I have a uVAX 3400 that works ok but I don't want any more. If anybody
is interested ten get back to me and we'll haggle, no reasonable offer
refused. Buyer collects it'll go very cheap to a good home.
The system is in GLoucestershire outside stow on the wold.

Hello,
I have in my posession a Video Brain home Computer, It is in mint
condition, however I cannot find anything on the internet about it.
I see listings on some of the collectors web sites but no pictires or

Can you help me find information on this apperently rare home computer.
Thank you for your input..

I have just been offered a pile of PC/Xt stuff, along with a couple of
things I wanted. If anyone is interested in old cards, MFM hard drives
and the like, and are in Sydney, I could pass on the email address of the
person making the offer - he wants a bit of money for it all, but not too
much - I just already have more XTs than I want. :)
Adam.
We just received the donation of an NEC APC, (built in monitor, two 8"
floppy drives, MSDOS 2.11) for our museum collection. It works, but
naturally no documentation. Can anyone give me information on the pin-outs
for the com port and printer port? (Both look like Centronics connectors)
Best wishes to everyone, and thanks for all the help you have provided
over the year.

Hello, all:
I got a Kodak digital camera for Christmas, and I was suprised at the
quality of the pictures. But, I anticipate lousy battery life from repeated
downloading, picture taking, etc.
The docs say that I can use a Mac Powerbook 140/170 AC adapter to power
it. Does anyone have a spare that they can sell me?

<don't know enough about head technology, though I assume that the head
It's littly to do heads ot specific systems. *ALL* drive before the
3.5" sony standard were capable of the dasterdly deed.
Reason, the line known as write enable not. This is an active
low(ground) line and when power went you had the head in contact,
some power and a command to write a logical transistion at that point...
BANZAI!!! Some systems were better in they would lock out write commands
if power were failing (assuming both used the same power.). My NS* has
such a mod and it's allowed me to avoid early bit disks! It's fairly
trivial to put in a system where the drive and all run off the same
power supply/switch. The TRS-80 and like systems were prone due to each
being seperately powered. FYI the safest was powering off the drive
first.
FYI: for a while I was using 360k drive on non-PC and the risk was
always there, unless hardware prevented it external to the drive.
The 3.5" drives put power fail on the drive avoiding all the pain.

I remember my heathkit (H-89) had a similar warning about starting up with

When all else fails I use an old (Packard Bell!) 286 setup program that
seems to work most of the time. Won't work on nonstandard HDD tables,
though.

How 'bout CD-ROM's? <g>
Don't DARE plug that drive into a //c!!! I did it once (not with my own ones
:) and it fried the //c, leaving the drive intact (I think).

As far as I know the 800k Apple drive you have described can only be used
on a Mac Plus or better. Or a modified 512k. I really doubt that it will
work with a //c. I could be wrong...

This is generally true for most everything but 3.5" floppy disks,
TU58 dectape and harddisks(there are exceptions).

If I'm not mistaken (and I might be) the M10 is one of the family that
includes the RS model 100, NEC 8201a, a Kyocera (I forget the model #, but K
made 'em all) and one or two others.
No floppy, what's a hard drive?, but eminently useful and probably one of
the rarer machines in the family. iirc, it had a pop-up screen, which none
of the others had.
Actually, it's an evil piece of garbage, and you should send it to me right
away. Don't hesitate, your life could be at stake! 8^)

No, 8296 is a very late PET. I have three of them, but one lacks a
keyboard. Good old PET 8000 series architecture, although I'm told some
have a later version of BASIC. 128k of memory, but I think you can only
get at 96k + screen.
The 8296-D was the built in disk drive model. Twin floppies, DSQD, on
the GPIB internally. Uses a later version of the Commodore DOS software
than I have docs for :-( (Commodore disk drives all had a CPU in the
drive unit that ran a system they called DOS and communicated with the
system unit over the GPIB or the later VIC/64 interface)
My advice to you: GRAB IT!!!!!!!
Philip.
PS I once found an 8296D in the skip at work. I asked to buy it and was
told officially no, not safe, PSU is playing up but unofficially I could
grab a few parts if need be. I did and upgraded my (then only) 8296 to
the D spec. It cost me _more_ to do the upgrade than it would have to
repair the original machine. I was not pleased...
Someone near Sydney just offered me a pile of stuff, mostly old pc/xt bits.

the Sharp is one of the plamtop models they produced, rather than the more

Thanks heaps,

I had my Apple 800k running on my 512k, which started out as a 128k.

I picked up two macs today for $15 total.
the first one is a mac 512 and the second is a mac+ 1meg. both are missing
their mouses but they do work just fine. I also got two external 800k
floppies. One is called mirror magnum 800, but doesnt recognize a working
floppy. the second one is called an apple external 800 drive, but i've never
seen one quite like this. it's a bit smaller than the apple 3.5 drive, and
doesnt have the stripes molded in and does not have an eject button either,
only the hole to push a paper clip wire in. can this drive be used on a //c or
similar? current plans for these macs will be to take the best parts of two
512k macs and make one good one with the remainder going to my brother for a
macquarium project. <!> I already own a platinum colour se and this one i just
got is a 1meg beige colour se. is there any significant differences between
these two se models?

Hold in the "F" key while booting. You'll then be able to boot off a disk in
drive A.

I'm looking at picking up an Olivetti M10, but I don't know too much about
this one. I'm told that it has neither a floppy nor a hard drive. Can
someone enlighten me, or at least point me in right direction for more
information?

How do you get in the cmos on a Grid 1660????
Some body brought it to me and said it could not find A drive and when I looked it had 5 drives A.C.D.F.H. And when I got rid of H drive it took the Operating files with it. now I got disk error and I want to get into cmos to see if I can format the drive and start from scratch.

I saw one of those at the UW-Madison surplus sale a few weeks ago,
at a similar price, but passed it up. It looked like an A/D box of
some kind, I too saw the apple logo and wondered if it wasn't for
the Apple II era - Isaac Newton, get it? I definitely saw A/D converter
chips in there, maybe they were on the expansion cards. No CPU necessary,
it could be driven by TTL logic if it was just spitting data.

Many thanks to all who responded with advice, part numbers etc. I have
passed the part numbers on to my colleague - I shall try Don Maslin's
suggestions for a web search next.

I think I have an 85 as well - in fact I know I do (somewhere) - I must
look and see what state the belts are in, and if I can measure them...
If not some measurements off yours would be very useful.

You could even go with an IDE hard disk and 2400 baud modem if you could
find them.

That part is totally true. It was aggravating trying to remember to take the
tapes out. I ended up ruining 1 or 2 that way.
