   I doubt that there would be any NS16550s left out there.

   However, beware of a chip labelled "MX16C550A"!  I was assured through & 
through that it would be "100% compatible" with the NS16550AFN but, during 
testing, I found all sorts of strange behaviour that I did not get from an 
NS16550AN.  I'm also told that Western Digital 16550s have wierd catches as 
well, so:

   BE SURE, WHEN ORDERING 16550 CHIPS, THAT YOU'RE GETTING A *NATIONAL 
SEMICONDUCTOR* PART!
