     Not as it sits.  There are public domain programs which will use
the RS-232 pak, however (Mikeyterm) and if you have OS-9 any terminal
program will use the RE-232 pak (Xcom9 in particular).

     I'm confused.  Why not just use the Reset button alone?  You mean
from a machine language program?

     It depends on the program.  Some of the Rainbow stuff in BASIC need
to have speedup pokes removed.  Some machine language programs will need
to have their locations checked for address conflicts.  I can't think
of a generalized answer.

>only run in black and white?  Since I type in a lot from Rainbow, 

     I take it you're talking about the high res-color programs which used
black and white signals to produce color ("artifacted color")?  They have
to be rewritten substantially.  No quick answer--just have to learn the
new color capacity in the GIME chip.

     The color problem?  Anything that uses hi-res color is not going to
show in color.  Check the CoCo manual and it'll describe what addressing
modes will work on the new color chip.

     BASIC only works within 1 - 64K addressing space.  It doesn't know
about the rest of the memory pages (at least not in terms of direct
programming space).

     No, because BASIC is in the same address space as the user space and
the IO address and the screen memory.

     I don't know where you are, but I think the Well is a Fido/Usenet
gateway.  That may not help you though.
