Yep. That's exactly it. Also, the CIT-101 has a built-in clock you
can see in the
first setup screen. You send a (different) documented string to the terminal
(typically on login), and for a quick desk clock, tap the SETUP key once to
see the tab setup and a digital clock in the upper right corner of the screen.
Tap SETUP again and you are back at your OS's prompt.
I'm amazed to see so many references to them all at once, but I'd rank them
right up there with Wyse terminals as good VT-100 clones.
Somewhere, I have some paperwork for how much we (Software Results Corp)
paid for them in the early 1980s, but I want to say between $1200 and $1600,
*each* (the higher price may be what we paid for real DEC terminals).

A Teletype Model 43 could be considered "portable", and to my
recollection it used a 7x9 dot matrix printhead, which did lower case
nicely. It also used "real" paper as opposed to the thermal stuff of
the TI Silent 700's. It was definitely noisier than a Silent 700, but
the 43 was very nice to use.
I used one of these for a time a long time ago, and found it to be a
really nice terminal for use on timesharing systems. Would love to find
one today.
I have a couple of TI Silent 700's in that have built-in acoustic
couplers, and do lower case...except that the lower case is just a
shrunken down version of the upper case character set. Readable, but
definitely what you'd want to print out RUNOFF documents with. Plus,
that thermal paper isn't very durable for long-term document storage.

RUN/STOP-Restore is what you're looking for, but with many programs it
doesn't work due to their hijacking of the metal from the ROM.
Wow, a question I could answer.

They have been reworked. In the 70s 74S cost enough more I doubt DEC would
have used them in a function where speed wasn't reqired. It's entirely
possible someone trying to be true to date used "S" parts. Myself I will
not put 74S or 74F in with slow 7400 and I'm wary of 74LS in the wrong places
as well. I've been bit by those intermixes in the past, especilly when
the part was used as a oscillator, oneshot or other variations of normal
logic.
In DEC the BOM was it and ECOs were required to deviate.

I find the _need_ for pullups worrying. Despite the IC tester there is
something odd going on. It could be the parts pass dynamic but not static
parameters.

I'd be willing to help.

Hi All,
I have two Sun systems that I would like to find new homes for, any
takers?
One is a Sun Enterprise 2 and the other is a Sun Enterprise 450 (this
one is pretty good size).
These are free to a good home, though any donations of Data General
Equipment (always) and
as of late, Commodore Vic 20 equipment, is greatly appreciated.
The systems are located about 20 minutes North of Detroit, Michigan.
Thanks
Rob

But now the Macs have Intel processors in them too.
Any chance of arranging an event (but obviously smaller) in the UK?
Anyone want to come and see my 1962 ICT 1301 mainframe?
Maybe not quite as nice as the recent tape drive picture, but what do
think of
my Ampex TM4s :

There are UK events, such as Big Bash 4, but
I don't know what sort of retro computers
they are aimed at having never been to it.
