Guru's:

Since my NoCan-8MB contains video
memory bits from 0..F, Is there
a way to modify NitrOS9 to use it?
---

I've used debug like this:

DeBug
DB: .ff9b
    FF9B 17
DB: =0F      gives a new video page
ROM Memory   <---<debug complaining?
    FF9B 17
DB: =03      comes back gracefully.
---

Any number put there ($FF9B) gives a
unique video page. Kinda fun to watch it.
Does not crash as long as 03 is put back.
---

Not expecting a NitrOS9 re-write,
Paul T Barton
