Andreas,

What you have is more commonly called "A MITE".  That is because the MITE 
Corporation made them. See this web site:
<http://207-207-72-42.ip.theriver.com/development/teletype/mite/>

Manuals are not too easy to find. There are at least two or three different 
manuals that cover different variants of the thing.  David Ross scanned and 
posted one of them:

Robert Downs offers reprints of some MITE manuals:

Email to him to see what he has - my info above may be out of date.


The connector needed depends on whether you have one connector back there 
or two.   I'd be happy to find a source for them. I need one or two of them 
myself.  I have one MITE with a single connector (12 pin, I think) and one 
with no connector, it having been removed by a previous owner.  (So I need 
two 12 pin female cable connectors and one 12 pin male chassis mount "panel 
mount".)  From Newark's price (see below) you will figure out why I have 
not ordered from them.

 From another fellow:

The correct connector is hard to find but William Perry may have them:
I have his web  address as: http://www.williamperrycompany.com/ but it is 
not working just now.  It appears to me that the 12-pin connectors are 
called as follows:

"The chassis connector on the Mite is 165-11 and thus the one on the cable 
must be 165-10."

I found one company which has none in stock but a bit of further information:

The AMPHENOL Part # 165-10 12 POS C.CONN 8527
The AMPHENOL Part # 165-11 12 POS CIR CONN P/MOUNT S/CUP

I assume that "C.CONN" means cable connector
and: "P/MOUNT S/CUP" means Panel mount with solder cup pins.

It appears that Newark Electronics lists them.
They have over 100  in stock of the 165-10's at a cost of only #85.00 each.

The catalog page that is useful is:

I have the "few pages" Marine Corps manual in PDF form for the TGC-14, 
which uses the 12-pin connector. I would be happy to email it to you..but 
the URL is given above.  It's 1.7 mb in size but does have the pinouts for 
the 12-pin connector.  This is just parts of the installation and operation 
manual, it does not contain info on fixing or adjustments.  It may well be 
that such information is included in the full version of that manual.

Some MITE's ran on 24 volts, and I have a hint that such a model would have 
a different rear connector, but that is not confirmed.  So be 
careful.  MITE's seem to have been delivered for different power 
sources.  They also seem to have extra gears inside the case to allow use 
on 60, 75, or 100 WPM. You need to investigate what gear set is installed 
and whether the other ones are present in the storage spot inside.

If your MITE is set up for 115 volts AC, and has the needed gear set, you 
may want to either jury rig enough connections to the rear connector, or 
wire connections inside to the right pionts and bypass the connector. 
(Please don't remove the connector you have and discard it.. send it to me, 
thanks!)

Neither of my two MITE's are running yet.. they are a future project 
here.  Folks with experience with them say that when they run, they run ok. 
But if they don't run right, they are hard to fix.

I have a notes file on the MITE's and will be happy to forward it to 
anyone.  (The list does not send attachments.)
