I have been working with a VAX780 sim running
Unix System V r2 VAX780 and am having strange
issues.
TERM is defined at vt100
When firing up vi at times the cursor is positioned
in the wrong place or when inserting text it over
writes areas on the screen.
I have tried vt100, vt100-am, vt100-nam and none
work as expected.
Any ideas? Thanks
-Ken
Happy holidays

I have most often encountered this when my terminal window size was
larger than exactly 80x24.
If you're using Xterm or Gnome-terminal or a Windows terminal, for
example, make sure that the window is exactly 80 columns wide by 24
lines tall, or the VT100 termcap inside the emulator will be very confused.

The concept of a resizable window didn't appear until GUI interfaces.
Originally the hardware terminal had one specific size and vi depended
on the screen being that exact size. I suspect that SVr2 was in that
category, as the Sun merger of SVr4 would have been the reason to
incorporate it. So try a 24x80 window and see if it behaves.
Try "stty -a" and see if it mentions rows and columns. If not, what
terminfo says (try "infocmp") is what vi will believe.
It might also matter how you option your vt100 emulator, and even the
native vt100 had setup options, such as wraparound (terminfo calls this
auto_right_margin or just am). Vi depends on knowing what the cursor
does when it types in the rightmost column.

That’s not entirely true. The VT100 could switch modes from 80x24 to
132x14 (the latter was pretty ugly) or with the AVO 132x24.

For the record Ken's scripting appears to work with my copy of SimH vax780 albeit
with some non-fatal errors, probably different configure flags vs. the static copy in this
archive. I'm on aarch64 so can't use the vax780 binary in there but after boot
the images seem to run fine for me. Dunno what distros do, my copy is upstream.
Typing "unix" at the double "$" prompt starts the bootstrap. Running
uname(1) returns the expected properties for SVR2 for the VAX-11/780.
- Matt G.
P.S. SVR2 is post-1983 so a little touchier, so just some caution on distribution. Not
sure if there's any IP ownership differences concerning materials that said
"Western Electric" and/or "Bell Laboratories" in their licenses vs
materials that said "AT&T". Some clarity from the interested parties would
be helpful but I have no clue what the likelihood of a second round of free-to-study
licensing of later SysV codebases looks like. I would have to wonder if the licensing of
illumos has some technicality where all code SVR4 and back (that being the split point) is
technically covered under their license. I'm no lawyer so *shrug*

The 132-character screen width was for displaying files originally
formatted to be printed on a line printer. Compiler listings and
linker maps, for example.

Speaking of how VMS handled escape sequences, in the 1980s I
swung both ways (e.g. VMS and Unix). When DEC announced TERMTABLE,
a termcap-like library for VMS, I thought it would be fun to
write a termcap to TERMTABLE conversion program, so I did.
I thought this would let me run VMS TUI programs on non-DEC
compatible terminals.
This turned out to be a bad idea because none (?) of the DEC-written
programs actually used TERMTABLE. They were all hard-wired to use
VT100 (and VT52?) escape sequences. As I recall, I couldn't find any
programs that used TERMTABLE in non-trivial ways so I gave up.

Tom smiled while reading that man page: "It is assumed that the TN print
train is being used."
I have to wonder how many younger programmers know what a print train is,
much less what it looked like (or how heavy they were when you
changed them). Also, with the loss of the use of real lineprinters, you
have to wonder if those same folks understand why the asa(1) program that
POSIX.2 requires is there (although IIRC later *.2 revisions moved it to
the "FORTRAN Runtime Utilities" as an option POSX2_FORT_RUN - but we had it
there in the original draft).
Paul -- you left out the other "feature" -- the noise, which was still
deafening even with a model N1 and its cover.
I equate four sounds to my early computing days: the ASR33 printing, a 1403
printing, a 1402 reading card, and finally, the constant fan noise in the
machine room, plus the smell of light machine oil [definitely in a terminal
room of ASR33s].

I have to wonder how many younger programmers know what a print train is,
For the edification of those who don't know, the 1403 line printer and
its brothers worked like this. There was a (removable and switchable)
horizontal cartridge that sat midway in the printer, laid out
horizontally across the paper, behind an ink-soaked cloth band located
between the print train and the paper. Behind the paper was a series
of 132 hammers (one per column of print). The cartridge contained a
single chain of type that was spun at high speed. Whenever the
position of a desired character passed in front of its desired colu,
that column's hammer struck the back of the paper and thus printed the
character.
There were several print trains available, just as there were several
typeballs for the IBM Selectric typewriter. One of these used a space
character ' ' both for the space and for the underscore '_'. This
was the origin of using underscores to represent spaces in program
identifiers.
The other way to do line printing is to have a rotating drum with the
full character set for each column. This is the way the DEC line
printers worked. Of course there were minor inaccuracies in the
timing of the hammers, and with the drum-based printers this resulted
in wavy lines. There were inaccuracies in the print train-style
printers, too, but waviness in the columns is not as noticeable to the
eye as waviness in the lines. Coming from the IBM world, I considered
the DEC printers total junk.
Paul -- you left out the other "feature" --

Yes, the 1403 was very loud. The pitch of the noise varied with the
sequence of characters being printed. Some IBM hacker (yes, they
existed) came up with a deck of cards that, when printed, played
"Anchors Aweigh" on the 1403. IBM field service wasn't very keen on
this hack because it put a lot of wear-and-tear on the print train.

Thank you for this, I never knew how this worked. My experience as an
IBM 360 (USC-ECL) operator was brief and I never got into the nuts and
bolts.
I vaguely recall, as a teen, taking a tour of a DEC-10 shop in about
1970 in Portland. Their printer played "Anchors Aweigh" and I never knew
how. But now I wonder - does this mean they had an IBM 1403 connected to
a DEC 10 somehow?

It certainly means they had some kind of chain or train printer, but any
place big enough to have a PDP-10 would probably have had the budget for a
serious printer as well. I don't know if DEC made a competing printer (I
think they were very early with dot matrix printing?) or not (or who other
than IBM made big lineprinters), but once you know the trick is possible,
the rest is a relatively simple matter of having someone with a good ear to
tune the printer output so it sounds right.

Until the DECwriter series and the VT04, DEC sold OEM printers and
terminals were made by other manufacturers. Paul is speaking of the
traditional LP01, which Centronix made (I think) IIRC [Datapoint maybe -- I
forget], and it was ordered with either an upper case only drum [faster -
as it had two copies of the A-Z set] or an upper and lower case drum -
which included some special characters. The 8-bit parallel interface was
defined by Centronix, which was the standard printer interface for Minis
and later PCs. The difference with the latter is that IBM used a common
ground wire so they could put it in a DB25S connector. With the PC, IBM
designed the interface using a bi-directional Intel parallel I/O chip so
you could read it - which was not true of the earlier interfaces for
PDP-8/10/11.
As for the LP01 drum, it was possible to replace in the field but a PITA
[we did when we got a used one from Tektronix's Finance shop that was
running RSTS Cobol and moved it to the Teklab's 11/70 - V7++ UNIX system].
FWIW: when the Printronix was released in the late 1970s, it became the
standard lineprinter for UNIX sites until the rise of laser printers.
As for putting a 1403 on a PDP-10, I suspect it was possible, but it
probably took some custom interfacing.

They very well might have had an IBM 1403 printer on their PDP-10
system. DEC marketed the PDP-10 as their commercial raised-floor data
center computing solution. They OEMed a lot of the high-end
peripheral gear for the DEC-10/20 from third-party vendors in the IBM
world. The high-end disk of the time was an OEM version of the IBM
3330 with an IBM block multiplexer channel-to-DEC MASSBUS adapter.
DEC was notoriously bad at producing 9-track magtape drives. But they
were smart enough to OEM high-end tape drives from Storage Technology
Corporation, which made the gold standard of tape drives in the IBM
data center world.
So DEC did have the capability to attach IBM gear to the PDP-10. They
would certainly have an incentive to use 1403 printers in this market.
Nobody familiar with IBM line printers would consider the standard DEC
line printers acceptable. The 1403 was typically connected to the
S/360/370's byte multiplexer channel (transmits one byte at a time to
each device; intended for slow peripherals such as card readers, line
printers, card punches). I know DEC had IBM channel adapters for
disks and tapes usually attached by selector or block multiplexer
channels. They may have had a byte multiplexer channel adapter, too.

I guess the 1403 was the original multimedia output device.

The holidays always seemed to feature people running programs which played festive songs
by punching fully laced cards or printing patterns on the line printers. Whenever I
noticed something, I'd ask the operators to kill those programs because they could
cause equipment failures. A fully laced punch card is much more flexible and likely to
jam. Printing all columns on a printer, especially doing so without a line feed, tends to
moisten the paper which tended to gum up the print trains.
Those line printers were definitely noisy. I've got tinnitus thanks to working
around them.

The night operator for the High Speed Job Stream at the University of
Toronto would nap on top of the 1401. He would be woken by the lid lifting
him up when the printer ran out of paper, an effective alarm clock set to
the computer's cycle.

I have to wonder how many younger programmers know what a print train is,
much less what it looked like (or how heavy they were when you
changed them). Also, with the loss of the use of real lineprinters, you
have to wonder if those same folks understand why the asa(1) program that
POSIX.2 requires is there (although IIRC later *.2 revisions moved it to
the "FORTRAN Runtime Utilities" as an option POSX2_FORT_RUN - but we had
it there in the original draft).
Paul -- you left out the other "feature" -- the noise, which was still
deafening even with a model N1 and its cover.
I equate four sounds to my early computing days: the ASR33 printing, a
1403 printing, a 1402 reading card, and finally, the constant fan noise in
the machine room, plus the smell of light machine oil [definitely in a
terminal room of ASR33s].
