Dear All,

As my SecondSight... (is still under repair at Henry Courbis' home and
I understood he is a busy man which would explain why I have no news
from him, I just hope he is going well)

...I was reading the SecondSight documentation about shadowing, the
process which reads the Apple II bus and whenever some data is copied
onto a TEXT/GR/HGR/SHR page (A), it is "shadowed" on the VGA board
memory and then displayed.

I was wondering whether that process was hardware related or software
related. I mean, if one succeeds in writing a 8-bit QuickDraw II (and
all of its numerous patches on other tool sets), will that be possible
to allocate IIgs RAM for a 8-bit display (one bank for a 320*200
screen, 4 for a 640*400 one) and let the SecondSight know where the
pseudo new SHR screen is located in memory, so that it would perform
its shadowing process from there and not from (A) ?

Another means would be to write a Z80 version of QuickDraw but that is
another job!
