I've just been handed a small DEC badged unit, which I think is a terminal. It appears
to have been made by Termiflex.
It is a handheld unit with a two line LED display, a 4x5 keypad, three unmarked buttons on
one side, and a wheel device on the other.
It has a 25 way D type and a 3 pole AMP connector.
Does anyone know anything about it?
Jim.

It sounds like the hand-held terminal I've seen in RA81 docs - there's
a DB25 and some sort of molex-type connector inside the RA81 to plug
into. I think the 3 unmarked buttons are "shift" buttons for the
keypad.
Check the RA81 service manual...

That's the one!
Thanks to everyone who replied. I'll go and have a play.

Not being intimately familiar with all the DEC nomenclature, is there
any site where this sort of thing is summarized in table form?
KD11, RA81, RP04, LA36, VT100, etc., they all follow a pattern and it
seems there is even some consistency "R" for disc drives, "VT" for
video terminals, etc.
However, for those of us that don't have this sort of thing memorized,
it sure would be handy to have an online reference.

It's almost what you want, but it's not a complete list: there's a list
of two-character device mnemonics supported by XXDP on the last page of
my XXDP manual+notes, at
http://www.dunnington.u-net.com/public/PDP-11/XXDP.pdf
Note that there's a longer list of mnemonics on pages 3-5 of that
document, but those ones are not the standard ones used for device
drivers etc. They're used for unique naming of XXDP diagnostic programs.

You probably want the "Dick best" list, a comprehensive list
of DEC parts over the years. There are a few on the web but
I don't know of an electronic version (as opposed to a scan).

Is that not the database you supplied me with, a few years ago? A search
for RA81 in the parts field reveals quite a lot of hits, for instance,
although the descriptions leave a lot to be desired!

Generically speaking, it's just a "terminal", but the RA81 has the
power plug for it right next to the DB25, meaning that they were made
to work together. As Tony mentioned, you can hook a regular VT100 to
the RA81 (I've done that when diagnosing HDA faults), but for Field
Service, they can't assume that all customers will have a terminal
within 6' of the drive so they have a portable terminal to snoop on
the drive innards.

Check the RA81 service manual...
That reminds me, anyone have a copy of the RA82 service manual? I
have an RA82 that doesn't seem to do much and I can't get any response
from a terminal attached to the diagnostic port and the
LEDs on the
controller board don't seem to behave as fault codes listed in the
RA81 service manual.

THis sounds like the pocket terminal that field sevice used to run
diagnostics on RA81a, TU81s, etc. It's shown in some of the manuals for
those devices. You could use a normal CRT terminal for this, but the
pocket one was easier to cary around.
The DB25 is normal RS232, I assume it's wired as a DTE. THe Amp plug is
power input, I forget the voltage (it's likely to be either 5V or 12V, I
suspect the former).
