The manual I have is in the form of a large format (8 1/2 x 11)
paperback, 237 pages with the authors of the software listed as Dale
Buscaino and Scott Daniel (apparently aka Progressive Software Design)
with the authorship of the manual given as them plus Michael Shrayer and
Harvard Pennington ("TRS-80 Disk and Other Mysteries" and president of
IJG). It was published in 1983 by IJG Inc. (the Thoughtware Company tm)
of Upland, CA. A Google search revealed a review from 1984 by Betsy
Staples, an editor at Creative Computing.
It was a rewrite rather than a translation of the original code and had
some expanded features and additional support programs.

New subject: Old ICL mainframe keyboard
Folks,
Anyone got any memories or info on an early to mid 70s ICL mainframe that
required a big keyboard known as the 7181/9? I've got one and I'm sure it
was used on the 2900 mainframes and maybe earlier - big desk console types
with built-in monitor but free standing keyboard......
Any info appreciated.
cheers

Hey, we've added a Dragon 32!
Also, we now have a 1973 Univac 80 and a 1978 NCR T-8255.
In about 10 days, we're going after a rare Wang VS-90 system outside of
Wilmington, Delaware.

We never used those particular devices at our installation, but I did see
some info on them (I think there was also a 7184 of similar nature).
These were synchronous, block transmission terminals - a screenful of
information was sent at a time (either system -> terminal or terminal ->
system). Used on the 1900 series and perhaps 2900s. Normally connected via a
7900 series communications processor (better known as a PF56), but some of
the last smaller 1900s (1901T & 1902T) had a built-in adaptor.

Anyone here on the list actually own one of these??? Any chance we'll see
one at an upcoming VCF????

You could've seen one at VCF 5.0 if you went on the tour to the Computer
History Museum.
In fact, you could have seen the (only?) mobile internet node (it's the
gray box truck parked outside the Visible Storage building).

When I first started work as an Op for the local council they'd just phased
out their old mainframe (I was sure it was a 2900 but could've been a 1900)
and upgraded to a dual node 2966. The old console had one of these keyboards
so that matches. The comms cable on this keyboard is massive AND it includes
240V mains.
I'll keep digging :)

All models of the 1900 series had (slightly modified) KSR33 Teletypes for
operators console* as supplied.
The interface was such that it was relatively easy to install a faster
serial ASCII device. As we did our own maintenance we were able to do this
(using, at different times, a 30cps printing terminal then a 120cps VDU+ a
printer) and I suspect that sites that were on friendly terms with their
support would also be able to do this even tho' it was not a "standard"
offering. The 10cps console was a serious bottleneck on large non-George3
sites.
I'm not sure what console a 2903 had (the 2903 was a 32-bit processor
microcoded to emulate the 24 bit 1900 series).
* The 1901 and the 1901A had a switches & lights console as standard with
the TTY as an option (strongly recommended!).
Most information in this posting comes from the second (final) edition of
the "Central Processors" manual as updated to 2/2/77 (manual number 4412)
... the source of the rest of the info should be obvious :-)
