Yes, it will.

There were boards made by Memory Merchant (Shuffleboard), Holmes, 
and Omikron (the Mapper).

There is also PC-CRoss-Zap, which runs under MS-DOS on the PC, and 
is supplied by Hypersoft at:

    PO Box 51155, Raleigh, NC 27609 USA

They also make Hypercross which runs on the Model III and allows
you to read-write, under TRS-80 operating systems, PC and CP/M 
disks.

CP/M

They also did Monte's Window, a TSR with notepad, calculator, 
calendar, etc.

There are memory-mapped versions of some software, e.g. Wordstar 
3.3, around for the Model 4.

You shouldn't need a mod for the Model III, which is built to take 
two internal and two external drives. It's the Model 4P that has 
to be modified to take more than two drives.
