I have a TZ30 drive (internal). The TZ30 is a 5.25" half-height drive and
can read TK50 tapes.

Our sawmill uses an HP-1000 for process control; it has an infrared paper
tape reader and an ASR 33 Teletype. And they all work. But I'd like to
replace the teletype with a PC. Does anyone know how to make a PC emulate an
ASR 33??
Thanks

I have replaced many monitor connectors (all VGA HD15s). They aren't
usually TOO hard to do. The hardest part I have run into is usually
getting the old one open. If I am doing a total replacement, it isn't an
issue, as I can just cut it off... but usually, for broken pins, I try to
extract the bad ones, and insert new ones... in which case I will dremmel
open the old casing, and replace the pin. Molded pins can be tough, but a
hot needle will usually melt away enough of the plastic to slip them out.
Then a dab of hot glue on the back side holds the new pin in place.
Certainly in my book, easier, cheaper and faster then sending the monitor
out to be repaired... but I know what I am working on... I would never
expect a regular office person (and in some cases, even a regular IT
person) to be able to do it.

Hey, since there is a discussion of protocol's going on... does anyone
have the specs needed to write an implimentation of the I-modem protocol?
(that's I as in "Eye" or "Myself").
I know it was created by John Friel (at least, that is what I learned
when researching the protocol). But I can't find any real specs on it.
The only other thing I know about it is Procomm Plus version 1.1B
supports it. I need it to download data files off one of my systems here,
and I want to write a nicer download front end for it. Right now I have
to do it manually thru Procomm... not that it is a big deal for me, but I
want to be able to let some of the other office staff here take care of
the job, and for them, using Procomm and sending ASCII commands isn't a
good idea (they will screw something up... they have in the past, and
they will again in the future).
If I can get the specs on the protocol, I can write a program with a nice
GUI to handle the logging in, and selecting data, and downloading it...
not to mention, then I can do it on the Mac, which means some of these
people can do it right from their desk.
I'm hoping some of you wizards out there might have the info I need. (I
have exhausted Google among other search engines looking for it)

As I recall it, QMODEM was the clone of Flugelman's program, and what
I was using was a clone of the clone. Remember, this was in the 80s,
and while programming, I was living the Hotel California lifestyle...

Those HDD15 connectors are a bit fiddly, and in a commercial environment it
makes sense to have an "approved" repair done if the equipment is very new,
as it has implicatons for the warranty. Also, some cheaper monitor cables
use twisted pairs instead of coax (yuk!) and if you cut off the moulded
plug, it can be a pain to sort out which wire is which.

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.

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,

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.

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.

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.

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.

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.

I want to eventually connect a card reader to one of my PDP 8's, and thus

So no, I dont have a specific application, but i'm not looking for something

By the way, it is still possible to buy blank punch cards you know. 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)
