So I suspect they weren't bothering to trick or redirect VDU calls but had their own graphics API (for which no software was ever written).
So presumably it would switch to full screen when using this. Or Be a
dual screen system, with the program outputting to the hi resolution
Which wouldn't be much use in the absence of software.
However, it does occur to me that it should be possible to run RISC OS
task windows outside the main screen ie those that would normally
appear in an edit/stronged/zap window. Either in terminal type windows
on the host desktop, or in unused space on the emulator's screen when
in smaller modes.
