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.
