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.

Just tried them again, and they downloaded with no problem. Must have
been some problem on my end. Thanks for the data.

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
56 Card Verifier
65/66 Data Transceiver/Printing
77 Collator 2, 1 no cover
82/83/84 Sorters
101 Electronic Statistical Machine 2, 1 no cover
402/403/419 Accounting Machine 3, 1 no cover
519 Electric Document-Originating Machine 2
519 ditto, Principles of Operation
528 Accumulating Reproducer
548/552 Interpreters
549 Ticket Converter
550/551/552 Card Interpreters - Principles of Operation
557 Alphabetic Interpreter - Preliminary
601 Electric Multiplier - Principles of Operation
602-A Calculating Punch
604 Electronic Calculating Punch 2
650 Magnetic Drum Data-Processing Machine
654 Auxiliary Alphabetic Unit
CUSTOMER ENGINEERING REFERENCE MANUALS
602-A Calculating Punch - w/wiring diagram
77/85/87/89 Collators
402/403/419 Accounting Machine w/wiring diagram
24 Base 24/26/27/28/46/47/56/65/66/526/534/536/824/826/834/836,
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.

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
NetCommanders here. Quite nice multi-port RS232 and parallel
'switchboxes'.

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.
