[Coco] model 4 cp/m

[Leon Howell]

By the way, The ibm pee sea came with a later version of the same Basic as the 
TRS-80 Model 1 in rom, booted dos then loaded the disk extentions to Basic 
from dos just like the Model 1, so you could almost say the pee sea is a wanna-
be TRS-80 running a CP/M rip-off. That would make the pee sea inspired MSX 
sort of like a huge TRS-80 upgrade.

There is a ZX81 emulator for MSX, so why not TRS-DOS? Either way it will run a 
lot of programs like Wordstar and Visicalc that are data-compatible with the 
CoCo.
