Then Randy Cook came out VTOS 4.0, but never finished
it.
"Documentation" was mostly just a feature list. The publisher (Adventure
International/Scott Adams) wouldn't pay him royalties.
Lobo Drives created a new expansion interface using a 179x chip for double
density; TRS-DOS would not work with it. They purchased rights to VTOS,
hired everybody they could get their hands on (such as Roy Soltoff aka
Misosys), and came out with LDOS.
Radio Shack came out with the model 3, and Model 3 TRS-DOS 1.1, 1.2, 1.3
Radio Shack came out with their own version of the Percom Doubler (179x
for model 1). And licensed LDOS, renaming it TRS-DOS 6. Randy Cook
finally got royalties from Radio Shack.
Ldos was my fave TRS-80 OS
