I am interested in serial ports using the new 16550 UART chip:

What is the difference between this chip and the 16450 chip used in most
AT I/O cards?  What are the advantages/disadvantages in using this chip?

Can one simply pop in a 16550 in place of a 16450 or should one get an 
I/O card specifically designed for this chip?

Where can I get an I/O card using the 16550?  I would like a card with 
2 serial ports, a parallel port and a game port.  Who manufactures such
a card and who sells them in North America - preferably in Canada?

Please reply by mail or send me a copy of any followup postings as I
can't keep up with the flood of news and things often get deleted before
I see them.  Many thanks for any help on this.
