I just looked at a RO and KSR chassis (sorry, no extra RO).

I think you would just need to remove the keys/keylevers except for local CR and local LF.

Maybe need to remove the keyboard code bars, transmitter, etc, but probably not.

A new RO front cover seems like it would align the CR and LF keys properly.

Paul Cembura probably has RO front cover (153117) and chassis (152000) - better check those part numbers!

YMMV. No Warranty.

I want to convert a 28 KSR to RO. Aside from the much smaller plastic part on the front, what else would I need? Would it be easier if I searched for the entire chassis and front from an RO? Does anyone have one to spare?
