[GreenKeys] Parts to Change 28 KSR to RO

[Nick England]

 Pardon my confusion, but I am trying to understand.
The difference between 28KSR and 28RO is 3" front-to-back

Do you have a KSR in a floor-mount cabinet, and you want to turn it into a
RO in the same floor-mount cabinet?
IF SO - It seems like you have two choices
1) find an RO base (chassis) and move your motor and typing unit to it and
install it in the floor-mount cabinet
2) pull the keyboard parts off your KSR base (chassis) and put it back in
the floor-mount cabinet.
In either case you'd need a new 153117 RO front cover (plastic shroud)
which will save you the 3" on the front.
