To all,
The Computer History Museum's IBM 1620 Jr. project has already done
this.? We have converted an IBM Wheelwriter 1000 electric typewriter
into a computer terminal.? The conversion consists of a custom PCB with
an Arduino Teensy 3.5 microcontroller which is physically installed in
the typewriter, electrically in-between the keyboard and typewriter
motherboard, with custom firmware.
The initial work was to create a robust substitute for the IBM 1620's
console typewriter.? However, software changes are being completed this
month to extend it into a general-purpose, easily-adapted, ASCII
teleprinter.
We demoed the device as part of our VCF West display last August at
which we took 1st Place in Best of Show and 2nd Place in
Restorations/Replicas.
We will be making all of our design files, software, and documentation
available free to the classic computer community.
To whet your appetite, here's the step-by-step, illustrated guide for
the physical conversion of the typewriter:
https://github.com/IBM-1620/Junior/raw/master/docs/wheelwriter-adaptation-i…
We'll be posting a formal announcement of this device within a few months.
This work has been done by Joe Fredrick, Steve Casner, and myself.
Thanks,
Dave

Aw, that's too bad! The original Model I (CADET) 1620 had a console

Chuck,
True, the 1620 Model 1 Model B typewriter (1st gen).? The 1620 Model 2

Thanks, Dave.
Was the group mark on the Model 2 typewriter keyboard? I don't recall
it from the CADET. It was associated with the 1311 disk option anyway.
How does one print a flagged numeric blank? (the "dump numeric"
instruction prints it)?
Thanks,
Chuck

Chuck,
The Group Mark key was on later IBM 1620 Model 1 typewriters as well as
the Model 2 Selectrics.
See:
https://www.dropbox.com/s/p2b1449zr6uqh6p/IBM_1620_Console_Typewriter.png?d…
The flagged numeric blank was accidentally left out of the print sample
I made.

Thanks for that--I guess the CADETs that I fooled with way back when
didn't have the group mark on the typewriter keyboard. Didn't matter
much, as I mostly used cards, which allowed for some additional bit
patterns (e.g. 821 for a record mark).
I could see Dijstra's gripes with the machine--characters that you can
only move, not test for or do arithmetic on. Characters that you could
read, but not write. One thing that I never tried was to insert
numeric blanks, record marks and group marks into the addition table and
see what happened.
Did you ever try that? Would you simply get an error stop if one of the
non-numerics showed up in an addition?
Egad, I haven't touched one of the things in something like 50 years and
yet I can remember the numeric opcodes for much of it.
It's amazing that the machines were as popular as they were.
Ah, memories...

I would like to emulate a TTY, using a daisywheel

Well, there are Qume and Diablo.? Diablo was bought by Xerox, so some
of
them carry that label.

My first computer printer was a DTC-300. Diablo HyType 1 KSR.
Non-detachable stand.
Given to me by a friend who I gave a car to.
I created the manuscript for my Honda book on it.
TRS80 model 1 with "Electric Pencil"
I printed out drafts as 80 columns on 15" paper. Centered and double
spaced for the editor, flush left for the illustator, who loved having
a big chunk of space alongside to doodle in. Used to be able to get wide
paper with both edge tear-offs, AND a tear-off to reduce to 8.5x11.
One time, I got FOUR of them at John Craig's Computer Swap America.
Bringing them home in a Honda Civic was "interesting". Always have a
couple of skeins of rope in the trunk.
Getting rid of them when I closed my office in 2001 was "interesting".
But, a really great guy rescued me, and took truckloads of computer stuff
that nobody else would. Thank you, Sellam!
