It should be noted that extra K will run  on a IIe, IIc, or Laser 128 also.
I've been meaning to look into getting Daemon to actually run two 
seperate programs at the same time, one in each half of memory.  It 
wouldn't be too different than running background tasks.

Has anyone ever written one of these programs that runs a program in 
the other bank and switches?  I figure those of us with 2.0 Megahertz
or faster speed should still have acceptable speed.

Also I did some more work on Daemon and the Window routines over the summer,
but have been too busy lately to upload them.  The window routines still
have a bug or two I haven't killed, but as my parents keep reminding
me, I'm at college to pass courses, not write software.

Anywho, I should have somethin up in the next week, but don't hold me to
it.
