Because bank one runs at system speed, and bank $E1 (default) is only at 1 MHz.
                 ^^^--(well, you do reads and writes at this speed)

If $01/2000.$9FFF is being used by another program, then QD II will use bank
$E1. So..... if you ever request to use bank 1, and wish to do direct memory
writes, make sure you're actually using this memory. Almost always you'll get
this memory, BUT, if you're using the Orca/APW shell, you'll almost never get
this memory, Orca hogs. In my Software Experience demo awhile back, I did 
direct page 1 writes w/o checking, so about 50% of the time I had to reboot
Orca.. I have had no problems with any other launcher, including the Finder.

I've never let this problem bother me, but offhand, does anyone know how to
tell which bank QD II is using?
