Make sure it only prints 10 characters per second, then. (I think TTY's were
10 cps?) R-e-a-l-l-y s-l-o-w.

Yeah. 110 baud, 1 start, 2 stop.

I'd looked into this because I was at one point writing a terminal
emulator that would simulate the slowness and the ability to overstrike
characters. I didn't have a suitable font though, and since the slowness
was done at the front end, anything that produced lots of output was
uninterruptible on OSX (worked fine on Linux though

And the keyboard locks!  You cannot press a key unless the machine has finished transmitting the 
previous key.  “two key rollover” was a great advance in its day.

And don't forget that carriage-return takes longer than printing individual
characters, so you need to send CR LF to give it time to get back to the
first column while it's feeding a line.  Or CR CR LF just in case.

(Or was that the Olivetti terminal?  Or the DECwriter?  One of those
mechanical things anyway.)

Sending CR LF is independent of the CR delay requirements - the kernel
has options for several kinds of CR delays, IIRC at least one of which
is in proportion to the column you're returning from.

It's true that CR takes longer, but you have to send both CR and LF because
CR only returns the carriage whereas LF only feeds lines.  Skipping to the
bottom of a page was done by sending pure LFs, whereas underlining was
achieved (though the 33 had backarrow rather than underscore) by sending
a line of text followed by CR followed by a line of spaces and underscores.
Later, when it was observed that this made the text illegible on glass TTYs,
the order was reversed: spaces and underscores, then CR, then text.

It may have been the Olivetti.

That sounds like the Teletype model 33, and probably other Teletypes.

If you don't give it the extra .1 second of the LF, the first printed 
character will overstrike in the middle of the line you just typed.  And 
it will be "bold" because the print head is moving very fast to the left.

Normally you'd want the LF to advance, but if you're trying to underline 
by overstriking an underline character, you'd need to pad with a NUL.

The first model 33s I used didn't have an underline.  That character was 
a leftward pointing arrow, which I think was intended to visually show 
backspace, and some systems (GE BASIC, IIRC) used it as an erase 
character.  (Of course, there was no ability to backspace on a 33.)   
The caret printed as an upward pointing arrow, hence it's often called 
"up arrow".

This reminds me that someone at BTL threw together a "TSO Shell".  It was
a wrapper around /bin/sh that slept for 10 seconds before executing each
line...

All this talk about Teletypes brings up memories.  Model 33 TTY's were
single case and each "key" (which was tubular) had to be pressed down over
1/4 inch to register.  It was a significant effort.  The model 37 TTY's
that came along a few years later were upper and lower case (Unix was one
of the few OS's at the time that could handle both cases smoothly).  But
if you opened the case, what was in it was an astonishing assembly of
cams, levers, and other mechanisms.  When glass TTY's came along, they
took over quickly.

One of my most vivid memories of "paper" TTY's happened at my home, early
in my Unix experience.  The TTY had a box of paper feeding it, and the
output was also allowed to pile up behind it.  This "used" paper served a
critical role.  At the time, Unix had two kinds of files -- small and
large -- and if the system crashed (not uncommon in those days) when your
file was in transition from small to large the contents of the file were
lost.  It was also frequently the case that updates were lost in files
being edited.  So when the system crashed, you would haul up the terminal
output and highlight the changes that you made in case you needed to enter
them again.  This typically took a few minutes, by which time the system
was up again and you could start to reenter your changes.

So one day, I was heavily into editing when my wife, in the kitchen,
needed help with the kids so I went to help her out, leaving the terminal
running.  It was several hours before I was able to get back to it, at
which point I discovered that not only had the system crashed, but our cat
had discovered an alternative "litter box" behind the terminal and made
use of it!  Luckily, it was pretty dry by then, but that didn't help the
smell.  And, so help me, holding my breath I marked the lines that needed
to be reentered...

The other TTY story that surfaced happened to Dennis.  He had one of the
last model 37's as his home terminal, and it was getting quirky.  The
vibration of the mechanism occasionally caused a blank space to be
generated that he hadn't typed.  In those days, it was common to delete
the .o files after compiling because disc space was precious.  So Dennis
typed
"rm *.o" and Unix replied ".o not found".

Ah; an oldie but a goodie...  And who hasn't done that?  To this day, I 
still check the "rm ..." command before hitting CR, 30 or so years later.

In the late 1970s or early 1980s I worked over a summer in a repair shop 
for equipment manufactured by the German company Kienzle Apparate GmbH. 
Their keyboards were a marvel of electromechanical engineering. When a 
key was pressed the remaining keys were *physically locked*, preventing 
a second key from getting pressed. This was supposed to provide the 
operators with tactile feedback when they accidentally pressed more than 
one key. Maybe gratuitous over-engineering, such as this, contributed to 
the company's decline and the eventual takeover by Manessmann (1981) and 
then DEC (1991).

I picked up a Model 37 (ASR) for nothing at one point.   It was sitting in my kitchen and amusingly it was probably the only terminal that I didn’t have to turn on the nl->crlf mapping in terminal driver.   It also handled all those ESC and SI/SO codes that nroff put out for default to do partial line spacing and shifting from the normal roman to the greek letter typebox.    I also liked the fact that it used the full RS-232 modem control lines.   When the modem came online and asserted DSR it then turned on the motor.   When carrier detect came up a big green PROCEED light lit up.   The paper tape unit was a huge side car unlike the little integral one in the model 33.     At 150 baud it was really more of a curiosity at the point I had it.

Here too.  And my co-student Dave Snell had prepared me for it: "You
won't *believe* how fast this thing (tty) is!"  Even then (30 October
1969, the day the first packet went over the ARPAnet) I was
underwhelmed.

Is there an emulator for the 132 column line printer anywhere?
I'd like to take a file (complete with FORTRAN carriage control) and turn it
into an image (PNG or whatever), supporting overstrikes.

On my bucket list is to convert my collection of image tapes from the 
1970s, intended to be printed on an lpr, cut into strips, and taped 
together, into images suitable for a laser printer or a normal monitor.

What font did a typical IBM mainframe printer use, anyway?

A POSIX version that cranked out IEFBASHNONSENSE when run on Linux would be amusing ...

[TUHS] Teletype simulator?

Steve Johnson:

  This reminds me that someone at BTL threw together a "TSO Shell".  It was
  a wrapper around /bin/sh that slept for 10 seconds before executing each
  line...

=====

And after each command exited.  Discarding anything typed ahead
during the sleep, of course.

And printed all-upper-case IEFCRAPNONSENSE messages even when a
command exited successfully.

I think I still have a copy somewhere.  It dates from the 6/e era,
so it would need a lot of work to compile and run on a modern system.
Occasionally I think of converting it to ISO and POSIX even though
that seems contradictory somehow.

I hacked a terminal emulator to look like it once.
Fired up the browser running javascript, running jor1k,
running linux, running simh, running a v6 install.
http://dugo.home.xs4all.nl/ksr33.png for the result.

I kept the pipes that shouldn't be there on a
standard print head. Speed was controlled by
simh settings.

I reverted to the standard jor1k emulator for
the v6 demo[1] because I have no experience or
other reference for exactly how a KSR-33
exactly works and lacked the bandwidth to
even implement overstrike.

I saw one in a contest that emulated the sounds
and the moving parts at:
https://www.shroudoftheavatar.com/?p=41373
with source at:
https://bitbucket.org/slash_slashware/jsteletype/src

[1]
http://www.oldbsd.org/unixv6install.html
watch out, it is slow and runs on a limited set
of browsers.

Yes. I saw Clem's mail just as I was about to recommend
placing a small dish of machine oil beside the simulator. 
Alas, it seems I missed out on the chad experience. Data was 
regularly imported to the PDP-7 by ppt, but rarely exported. 
Night-owl Ken must have taken some ppt backups, evidence of 
which the midnight janitors whisked away.

Yes there is an emulator for the Mac that does both glass tty emulation with smearing fuzzy chats etc. and ASR33.  I'll have to do some digging through the old email.  To find the pointer.   


My memory is its a small dollars and my open source.  Clem

It's not exactly what you asked for, but you can try:

     http://www.masswerk.at/google60/

Keyboard and printer "clak" as you wished, and there is a typewriter-ish
font.

Pierre

P.S.: no need for a sorter, with this program.

And now we're working on ed, which assembles and runs, but has bugs.

This might be a strange request, but does anybody know of a "Teletype
simulator", a graphical program that acts like Telnet but prints characters
in a typewriter-ish font and "clacks" when they are printed.

I thought it would be nice to get a feel for what it was like to
use a real tty; I only used glass ttys (ADM3a, VT100s and so on).

Cheers, Warren

P.S Linux/BSD version preferred of course.
