I have no idea on that.  I know one of the signals I wanted to use for
a project behaved differently on the CoCo3 than older models (or so I
was told) but I don't know if it was SCS#.  That's been a couple years
ago.

Is that the actual reset switch you planned on using or is that just
what was available for rendering an image?
Is that the best location for a switch?  Resetting the machine and
page if it's bumped would be undesirable.  I'm not even sure it could
go somewere else and fit in a standard game cart.

I'd like to develop some stuff for the board, let me know how much it
will cost for one.  If you can provide the info on the ports ahead of
time that would be nice.
