[M100] REX in T200

[Russell Davis]

I am now the proud owner of a TRS80 Pocket Computer & A T200 with REX. 
My finders fee for a stash of Tandy stuff I pointed a friend to and 
wanted to know if It's 1. Possible/OK to pull the REX from the T200 & 
bung it in one of my M100 or M102's instead? & 2. Would it be more use 
to leave it in the T200 and leave the M100/M102 REX-less?
