Yeah, I remembered wrong, Z8 is correct... sounds like a later

How about this: can I try before I buy? Or are you willing
to let go of it for chickenfeed (like say five bucks)?

Most PCs running Windows either have installed or can have installed on
them a terminal emulator named Hyperterm which can do what you want.
However, the serial ports on PCs are RS-232C ports, while many ASR33s
had 20ma current-loop serial interfaces. You'll need to either get a
converter, or a separate 20ma current-loop serial card for the PC.
BlackBox used to have both of these, but they got acquired, IIRC, and
I can't recall the new firm's name...
For the paper tapes, once read in, you can just use Hyperterm's
file transfer... oops, NIX that, I see ASCII mode is not among
Hyperterm's file transfer options... Hmmm, you may need to use
something like PROCOMM PLUS or ProcommPlus/Win... they still
have the ASCII transfer mode. Or just run DOS and use COPY, I did
that with a PC and a friend's CNC machine a few years back, worked
quite well.

No, not PDP-10, PDP-1. Thanks to Al Kossow, I already have the manual for
MACRO, but he didn't scan the source listings (which are supposed to come
with the manual) and I haven't found anyone else who has a copy.
Any other listings (DDT, TECO, MIDAS, the LOGO programming language, TVEDIT
or any of the timesharing systems) would be interesting too.
I'm trying to spiff up the cross assembler that comes with Bob Supnik's
simulator, so that's why MACRO and MIDAS are important. I'm also trying to
understand Peter Deutsch's LISP, so that's why DDT is important. The others
would be just for fun. I already have Spacewar from
http://lcs.www.media.mit.edu/groups/el/projects/spacewar/sources/
but maybe someone has a newer version.
Thanks,

Got an IBM PC Convertible free for pickup in Austin, TX.
Works fine the last time I plugged it in 2-3 years ago,
has battery, AC adapter, and "port expansion" (serial, parallel,
etc) "pack" on the back. In IBM canvas carrying case.
Will not ship - pickup only.

IBM PC system meant something different back then :)
Here's the list, for Norm, Erik, Dave and anyone else who inquired or may be interested; a little musty but generally in good shape.
REFERENCE/OPERATION MANUALS
24/26 Card Punch/Printing
46/47 Tape-to-Card Punch

Wiring diagrams for 024 and 056 only
Also, some interesting pamphlets about system design, procedures & control with these machines and I'll even throw in ref manuals for a Honeywell 400 and the Burroughs B200 Series (not the famous B205, but 250-280).
The stack is abt 7" high, wt. abt. 10 lbs.
Don't know about any others, but FWIW, I see there's a 604 manual at:
http://www.spies.com/~aek/pdf/ibm/604_OperMan.pdf
What I'd like to do to save time & trouble is ship it all to Norm since he generously offered to scan it, and then you can sort out who needs and gets what.
mike/ccs
That's the baby, all right, but both the units and the manuals say "Products"; guess when they made yours that was the only product they had :) And these are the NC16 serial-only model, HW or XON/XOFF selectable, no parallel ports (but I do have some S/P converters... :)
And I was mistaken, now that I think back; the RJ45 model (which these are) can not select DCE/DTE, it's fixed (although I don't recall which).
$2995 (no, no decimals in there) when new!!!! Just found the price list. And these later models handled binary data a little better.
Did I mention modem/printer sharing, many-to-many? Or computer-less local e-mail & messaging (within 250 K of course)?

Are you sure that's not 'Digital Product Inc'? I have a couple of

I was never a big Kermit fan. It came at the very end of the days
when it would have been of most use to me (76-81). As a nearly
charter member of Ward & Randy's BBS, I adopted Ward Christiansen's
XMODEM protocol, and used MODEM/MODEM86 during those years.
First time I saw it was a copy that came with an 8051 protoboard in '87
and it gave me fits, being generally much less capable than a clone
of Andrew Flugelman's terminal emulator/transfer program (forgot the
name).
PROCOMM most closely resembled Andrew's program, so that became my
standard terminal emulator under DOS, and later Windows.

More stuff being made available by me.
I have 5.25" half height floppy drives, both HD and DD's. All working,
all free (+ shipping, or you can pickup in NJ).
I have about 10 of each.
Any takers?

Ok,
On the board:
SMS MODEL OMTI 3
FAB 005298 REV A.3
ASSY 0005447 REV A
Chipset is NCR 0380xxx family with SMS & OMTI labeling.
Paper label on one chip says OMTI 3127 and repeats the
assembly number given above. ROM is labeled 1002550-A,
3127(C).
If a working one of these doesn't get the drive going,
then the pro0blem was with the drive. But I was hoping
I'd killed the controller with improper termination.
It sometimes seems to work at first, but then craps
out as it warms up. The drive activity light comes on
and stays on at that point.
I'd sure love to get the damned drive backed up... I
think I have copies of everything on there, but perhaps
not.
Regards,

Now that the OT ramblings are dying down, a serious one (sort of):
Anybody have a use for one or more Data Products Inc. NC16/250 NetCommanders (Not to be confused with Diamond's NetCommander ISDN adapter)?
Need to talk to your 15 vintage RS232 systems in the garage from one terminal?
Need to have your single-port computer talk to the 15 terminals throughout your house?
Need to have your 16 computers talk to each other about you while you're away?
And all at the blinding speed of 19200 baud?
Or do you maybe just need another obscure piece of hardware sitting on your mantelpiece?
Then THIS IS THE DEVICE FOR YOU! Original cost SEVERAL 1000 $$'s each!
A 16 port cascadable RS-232 switch/hub/256K buffer, DCE/DTE programmable, allowing each device to talk to any other, either pre-routed or addressable in the datastream header; simultaneous multiple paths possible, even at different baud rates. Software setup (although they'd need 2 new AA NiCads to remember), unfortunately an austere front panel with no pretty blinkenlights.
BUT WAIT! THERE'S MORE!
If you order right now, I'll throw in your choice of P/S or S/P converter, parallel or serial buffer, auto printer switch or serial or parallel range extender!
Any serious interest? As usual, in the Toronto area, but if ya really can use one of these, unlike the Cromemcos it's almost practical to ship; not very heavy.
Might need a few $$'s though, to cover my time in checking one out and copying the docs, since there's only one copy.

Makes sense, since there is an LED 2 digit counter/display in it. It is

I guess it can step up the power. The game uses 2 D cell batteries
connected in series, so it gets 3 volts input power. Humm... thinking
about that, the choke coil could actually be a light weight transformer
then (maybe? I'm not an EE, so I am guessing since a trans and a choke
both have lots of wire wrapped around a magnetic core)
I will have to see if I can get a chance to draw up those schematics,
that will help tell more about it I am sure. Heck, I have to take it back
apart anyway, I need to either oil the motor, or replace it. The game
seems to still be working (thank god no perm damage from the battery
leak), but the motor starts to slow and stress at certain points.

Hi Lawrence,
Don't know yet what'll happen to the punch & cards; still trying to sort it out, along with the old IBM docs. Will keep you advised if it doesn't go to Erik in Holland or one of the other enquirers.
Can't interest you in some 8 ch. punched tape equipment instead? Nice Burroughs optical reader & punch, and a box + of mylar & paper tape, assorted lovely pastel colours and black :)
Hope u don't mind if I put this reply on the list, in case someone else can benefit from your tip about the cards.
And you haven't told me yet what Cromemco cards you need.

Subject: Re: punch cards
I want to eventually connect a card reader to one of my PDP 8's, and thus
I would want a method of punching some cards ;) I dont have the room
nor the ability to move a large IBM card punch unit, so a small unit
would be desirable. I'm still looking for a omnibus card reader
interface card.
So no, I dont have a specific application, but i'm not looking for something
to hang on a shelf and point at occasionally either. I do plan to use it
eventually.
By the way, it is still possible to buy blank punch cards you know. That
guy on ebay who is selling the selection of different types of punch
cards does sell them. I think his ebay name was key29 or key26, something
like that.
>How much should a PCjr PSU run me?
I will do some digging, I *might* still have a power supply or two
kicking around. I had shelves full of PCjrs not to long ago, and I threw
out all but one complete unit (PCjr, side car expansion thingy, wireless
keyboard and the wire for it, power supply, monitor). I tossed all the
PwrS's back then too, but I *think* I have seen one or two still floating
around (if you don't mind that it will have a number written on it in
white paint). Unfortuantly, the room they would most likely be burried
in, the lights are broken right now, so until I get around to changing
the ballast, I can't see very well (I just took a quick look with a
flashlight, but when I say they would be burried in there, I really mean
burried, it is about waist deep in one giant pile of old stuff).
If I still have one, I would be willing to give it to you/trade it to
you. (you can't have my last one, but worst case, I can tell you what the
pinouts are, and the voltages on them, so you can always try to build one
yourself... although they do have an odd right angle connector IIRC and
that might prove hard to find/replicate)

Please help find a home for this system:
This is one unique system giveaway...last of the dinosaurs wants a
good home; and we want the space it occupies.
The SGI PowerSeries III 4d/48VGX is a beast of an IRIX system (or was
in it's day). This system was a graphics workhorse that ruled the
world of high-end Structural Biology Molecular Modeling; chewing up
other systems in its wake. Today it is a fossil that could have high
appeal to a computer archeologist.
This system is about the size of a LARGE refrigerator, runs on 220V
power (and knows how to USE IT!!). The system is currently not in
operation; but for those that know how, or want a unique project, it
can be a serviceable working unit.
Expensive to purchase originally; reputedly around $250K, This is a
classic system that is destined as a museum piece...it would be a
real shame if this ends up in the being discarded.
Here's a couple of links on this unit and its family, for those with interest:
http://www.reputable.com/~skywriter/pstech/index.htmlhttp://www.geocities.com/SiliconValley/Pines/2258/4dfaq.html
You must be able to remove the system via your own transportation.
The system is located on the Harvard Medical School campus in Boston,
Massachusetts.
Please: Serious Inquires only...remember you must truck this system
out on your own; and removal in a timely fashion would be appreciated.

I just went to a local computer show today. I was happy to find that a
few vendors had components available from disassembled computers or
whatever. I picked up a 3com 3C905-TX PCI ethernet card, an ATI Mach64
video card, and a very nice Sound Blaster 16, all used of course. The
Mach64 had "Monitor" written in marker on the slot cover. Do office
people really need to remind themselves where to plug the monitor in? I
have also seen a 3.5" floppy drives marked "hard drive a:" and the 5.25"
floppy, marked, "floppy drive b:". What's the deal?
I also picked up a new AMD K6-II 500 to replace my IBM 6x86 233, and a

Having had some actual hands-on experience with these beasts
(I used to be a service droid for a Redactron Dealer), I say
deep-six the mutha'.
They're pigs to work on, and utterly useless without the
'printer' (actually, it's an IBM Selectric I typewriter
mechanism, with a belly plate *packed* with solenoids).
Electrically, not very interesting; most of the space in
the cabinet is taken up by the powersupply (ya gotta source
enuf current to actuate all them solenoids).
The 'brain' (if ya wanna call it that) of the thing is
just a 12" square board, packed with custom ceramic SSI
or MSI chips. There was another board with all of the SCR's
(I think, geez, that was like, twenty years ago).
ANyways, one of my fondest memories was the day I had to
service on one of these puppies at the Aberdeen Proving
Grounds in Maryland.
Those GI's schlocked so much wax on the floor in that office,
the damned umbilical from the cabinet to the selectric
was *stuck* to the floor! I gave it a good yank, and the
wax flaked off the umbilical like so much dandruff. Yeek.
The later Burroughs Redactor II's and III's were 8085 based,
and are of more interest . . .

Sorry Paul, got a little overwhelmed by replies to my various posts and did indeed miss you somehow.
Yup, except for some manuals (but there are lots more), everything's still here; just haven't found it all or sorted through it yet after my recent move. No 68000 stuff though, just AIM and S100 stuff (except for the oddball items and of course CBM and PC stuff, but I don't dare mention that here - but just in case anyone wants an original cassette PC MB or some of the interesting add-on cards from that era.... :-)

I'll have to keep an eye out for this book.

Does that book give the pinout for the serial port? The dang PCjr uses
screwy IBM square connectors. I had a need at one point to connect my
PCjr to a serial terminal server, but I didn't have the pinouts to make
an adaptor.
Any other goodies in that book? (It was probably the book used when a guy
built a few PCjr monitor adaptors to hook them up to CGA cards... I still
have a few of the adaptors... someday I should right down their config in
case I have to make a new one)

Maybe the name escapes you, because it might have been "HardCard". I have
two hard drives on a card. I know one is called "HardCard", I am not sure
what the other is called. I have never been able to get them to work (but
I didn't throw them out cause they were too cool). Interesting thought...
I always tried to get them to work in PCs (ISA slot)... humm... I wonder
if they went to my old Apple II+'s (is the slot the same? Although, I
don't think they would have, as IIRC, they would be too tall, and they
have the dust cover plate for a PC on the back, which just would have
made no sense in an Apple II)

I assume the tritium component is a modular part of the device, as
it has a rather short half-life (and IIRC, the last production facility
was closed down).

Sure thing...

Small (8 pin): AC TL496CP MALAYSIA (and has 140 verticle down the pin 1
edge)
I wrote everything on them, including country of origin, because I have
NO idea what is important and what isn't (for all I know, different
country origin chips have different designs).

The IBM PS/1 models 2011 and 2121 both use the same monitor with power supply
inside. I get several emails from people that buy the CPU but didnt get the
display with it. PCjr power supplies show up every once in a while around
here, especially at hamfests. In fact, I bought a jr a few months back with a
second story floppy drive that connects to the main unit. I'd like to hook up
my PCjr hard drive to it also.

I also have a PCjr and like you don't have the PSU. They come up on e-pay

including the IBM one, however, as well as some cartridges but they are
buried somewhere among my stuff which is still in disarray due to my move
this summer. When I run across them I'll let you know.

I just dug out my 2 "hard drive on a card" units (not to be confused with
a "hot dog on a stick").
One is a Plus Hardcard (says so right on it), I have NO idea what kind of
a drive is connected to it (4 small ribbon cables marked R/W, Encoder,
Motor, Rotor... don't know what kind of drive connects that way), nor do
I know anything about the size (40mb?, see below) or setup of the drive.
But the specs may be available on Quantum's (well, now Maxtor's) web
site... I do know I have seen Hardcard info there before.
The other one doesn't have a name per se on in. The physical drive is
marked Kalok, Octagon Disk Drive by the Kalok Corporation. Model# KL330.
However, I think that might just be the OEM drive the unit manufacturer
used. It looks like maybe an MFM drive (2 card edge connectors that look
like 5.25 drive connectors). On the back of the unit is a sticker marked
Part#: (blank), Model#: CARD30R, Serial# 9790, Date: 1/90. If the date is
right, then this thing is WAY newer than I thought it was. At one point I
must have had some specs on it, as I have penned onto the drive the setup
of it (616c, 4h, 26s, 32mb).
I flipped thru my binders of tech notes, and I didn't find anything on
the Kalok drive, but I found a page of notes on the Plus hardcard...
tells me how to change the IO and IRQ settings, as well as how to
repartition it as one drive. Seems it comes as 2-20mb drives, but needs a
device driver to work, repartitioning it as one 40mb allows it to work
under DOS 6.22 without drivers. I don't think I have the drivers, and I
don't think this is originally my page (it is dot matrix printed and that
doesn't jive with the rest of my notes), so my guess is, I found it in a
closet somewhere and clipped in into my binder.
Well... hopefully some of you cared about all that... if so, there is a
picture of the two drives at <http://www.mythtech.net/hardcard.jpg>. If
not... sorry to waste the bandwidth.

Here's some gleanings from my database of a2gs inf. I believe it was
supplied by Supertimer on the csa2 newsgroup.
---------------------------------------------------------------------
There are two things you need to do to get the IIGS usable.
First, get a hard drive for it. http://www.allelec.com/ Alltech
Electronics sells an internal hard drive for the IIGS that is
a hard drive on a card. No extra controller needed. It is
an IDE controller plus notebook mechanism. It costs $59.
For that price, you also get the most modern Apple IIGS
System Software, GS/OS (System 6.0.1), which is normally
on six separate floppy disks (a hard drive is needed to get
the most out of it). You also get tons of freewares and
sharewares. The hard drive is called the Focus hard
drive card. Look for it on the Alltech site.
The other thing is memory. Alltech (see above for web
site) also sells the Sirius RAM card. They are revising
their web site, so this product may not yet be on there,
but just call them and ask. It is a 0-8MB memory card
that can be expanded in 1MB increments using 1MB
30 pin SIMMs. I'm sure you have an old 386 lying around
that you can gut.
Only the IIGS can run a graphical OS somewhat similar to MacOS.
The IIGS' OS can, with the proper software, generate printed
pages on high resolution ink-jet printers and laser printers
with TrueType fonts, an Apple (same as Mac) style GUI, and the
use of the same keyboards and mice as the Mac (in fact, ADB
was first used in the IIGS before being used on Macs...pre-GS
Macs used "telephone" style keyboard cables).
The IIGS has built in support for 15Khz analog RGB
color. The IIGS itself has a 4096 color palette
and is capable of theoretically throwing up to
3200 of those on screen at once. The monitor the
IIGS uses will also work on the Amiga and Atari ST
and their monitors will work on the IIGS.

I believe the A2 FAQ by Rubywand and a bunch of
other stuff is still on this site or you can find it regularly
on the csa2 n-g.
There used to be older FAQ by one Nathan Mates a
notorious csa2 flamer who, in a snit, removed it from
circulation. If you contact me off-list I MIGHT be able to
tell you what was in it.
Since I've had an A-gs monitor for years and by the Law
of Affinity knew that a GS would eventually find it's way to me
(thanks Rich) I've kept this info and even the GS manual.

Does anyone know if an Apple IIgs can use an old Macintosh Hard Disk 20.
The Mac HD is NOT scsi, but rather uses the disk drive port on a Mac. It
was designed to work with older non scsi macs (128k 512k), and could be
daisy chained thru the disk drive ports (at one point, I think I had 3 HD
20s and a 400k drive connected to my 128k Mac).
The IIgs has a disk drive port, and visually, the 3.5" drive I have for
it looks just like the 3.5" drive I have off an old Mac Classic (I have
to go off visual, as the one from the Classic has no labels or other
markers beyond the apple logo... don't know why, that is the way it was
when it was given to me).
I was hoping maybe they used the same ports, and I might be able to use
the HD 20 with my IIgs so I can add a hard drive to it.
Anyone info would be great.

One gone, one awaiting its fate: T300 dual floppy PC semi-compatible, no monitor (but std RGB OK), spare KB, 2 sets of 3 manuals, 123 & dBII, diskettes & some tech info; also service info & schematics for T100. Good for converting 360 to/from 600 Kb diskettes.
Headed for landfill if no interest.

In the process of reclaiming basement space for other hobbies,
I have unearthed a box containing two complete years of BYTE magazines,
specifically 1982 and 1983. They are in very nice condition.
If you want them, please reply to me directly to arrange pickup
in central New Jersey, just off the Garden State Parkway.
At a later date, I might also be uncovering at least one complete Sony
SMC-70 (CP/M) system, perhaps up to two more system units and a number
of add-on cards. These probably won't be free, but certainly not eBay
prices. (I'd work a trade, but I really really need the space)
Again, reply directly if you'd be interested.
Thanks.
