Very strange, because when using Microport with several different motherboards,
the same problem exists. Also, when using Tandy XENIX on the same motherboards,
the problem goes away. Are you running anything while getting a LARGE (more
than 3 meg compressed) of news? Try catting a large text file from the main
console at that time, and wave bye-bye to Microport.
	By the way, the problem got better (did NOT go away) when we installed
a 20Mhz '386 board with 4 Meg of .6 wait-state RAM. The problem has also gotten
better when a faster (40ms as opposed to 65ms) drive has been used for news
storage. It seems to me that Microport needs to do some work on the device
drivers to get them running correctly on an AT.
