*If
an
8K
or larger memory expander
is
used, the screen memory moves from decimal
7680
(hex I
EOO)
to decimal 4096 (hex 1000). This allows for continuous user memory beginning
after the end of the screen memory. Color memory also moves when the memory
is
reconfig-
ured in this way.
It
moves from decimal 38400 (hex 9600)
to
decimal 37888 (hex 9400).
