Is NEWDOS a ROM we can install on Rex, or is it a COM file?
NEWDOS is a patched version of TS-DOS to install in REX (or a OptROM).

I guess to be accurate, NEWDOS is actually not just a patched verion of
TS-DOS. It is actually a re-assembly of it. I had fully disassembled
TS-DOS into a file that can be re-assemled by VirtualT. I then added
features to it, including detection of running on VirtualT, fixing the
DISK scroll bug, adding programmable delay, and ignoring DSR.
Reviewing the code and reminding myself what I did in 2014, I had
actually added an F7 key hander (non-DISK mode) to provide a UI
interface for setting the delay factor directly within NEWDOS. But it
has no place to save this delay factor ... just useful for easily
dialing in a delay factor that can be used in a BASIC call.
