I have seen RO bases with and without the contacts so you will want to look.... 
The contacts are simple enough to add "if you have them"
or you can run two wires from the keyboard contacts to a molex connector and add the mating molex connector to go to the wiring block of the machine so you can disconnect and remove the keyboard.  Either way accomplishes the same thing.
Also
I have seen just two wires run from the keyboard to the wiring block and you have to unhook them to get the keyboard out.

Let me clarify, the news agencies may have removed everything from the M15 units which
would not be needed for their services.

In regards to the M15RO units lacking the keyboard contacts, it is very possible that an RO may
have come from one of the news agencies and I suspect that the machines, if bought from Teletype
directly, were ordered as RO units and the associated contacts and wiring simply not installed.

Another possibility is that the news agencies may have purchased surplus M15 units and simply
removed everything from the units, simply to reduce failure points over the years of service as RO
machines.

Stan Voynick asked me about converting a 15 RO to a 15 KSR. I am posting my comments to the group.

I looked into that with my 15RO and it was not possible. The keyboard has sliding contacts that connect to the base. (Picture 1) There are mating contacts in the KSR base. (Picture 2) My RO does not have those contacts. Therefore a keyboard will not connect. I do not know if the RO base even has the mating keyboard gears. At my age it is to difficult to take the cover off to look. Maybe someone else can enlighten us.
