advantages such as faster, portable and
more reliable. But some problems will come to bother you too. Hereafter we like to point
out problems may be occurred and
show you how to settle.

could be already stored program, you can't write any
more, except you erase and program again.
2. If you forget to key in ROM SIZE (represented by 2,4,8)
the errors could be occurred when you use WRITE, READ,
COPY functions, please reset your computer and
boot AP64e again.
