Far as I recall, P&T never did a port for any of the Tandy 5.25"
machines -- just the 2/16/12/6000 series. A good job they did on
those, far superior (to this Tandy tech support guy) to that thing
Lifeboat put out. They didn't do one for the Mod 4 since CP/M 3
was announced for the Mod 4 when the Mod 4 was announced (though
there were a few months delay in shipping the package).
Any CP/M for the Mod 3 would have required a hardware change (as in
the Montezuma Micro upgrade for the Mod One) to put RAM in the area
occupied by the BASIC ROM(s).

They say that politics makes strange bedfellows.
Of course, the main reason they cuddle up is to screw somebody else.
