This problem is occuring without any background programs. There are no
desk accessories, no TSRs. I know what the symptom is and I know about
out-of-sync packets. I always run Elite with my hard drive turned off
and booting the program from power-up.

It is because I know about these problems that I posted my query --
There must be something wrong with my hardware to keep it running too slow
for the game. I want to know if there is some ikbd incompatibility where
the keyboard is sending joystick reports too fast for the system to process
them -- not at too fast a baud rate, just too close together.

Unfortunatly, there is no such thing in the Madison, WI, area.
