I am also interested in how readily converted the 1200XL is.  My understanding
from some of the previous posting is that the group in southern California is
converting 800XL's commercially and that they are compatible with the 130XE.
This is what I really want -- 256K 1200XL and 800XL that are totally compatible
with the 130XE.  I do not think that the source code mentioned in the Byte
article does this -- am I correct in my thinking or am I wrong?  Also, does not
the 1200XL use a somewhat unique OS?  I never saw any differences in what
programs that I ran, the 800XL and the 1200XL seemed to run the same programs
equally well, but the AMODEM4.2 program that would run on both the 1200XL and
the 800XL will not run on my new 130XE so there is something different about
the XE's.  (Probably having to do with their use of joystick port B (the
non-existant joystick ports 3 and 4 are used somehow for the access to the
additional RAM locations.)

Is there anyone doing the 256K modifications in the Portland (OR) area?  If so,
publicize how to get ahold of you.  Thanks in advance!
