The press releases I saw on XENIX for the AT said that it was a 3 user
system.  Is there any reason anyone can think of for this?

One news letter I read thought that it was to create a product
differentiation.

Could it be a lack of interrupt lines?

Does the AT run out of bus or processor bandwidth?

If uucp is 1 user that only leaves 2 others.  That seem a bit
restrictive.

The reason that the PC/AT running XENIX is only a three user system is
that it can support at most two serial ports.  That, plus the main screen
and keyboard, makes three users.  It sucks, but that's the way it is.

From the 10/84 BYTE, page 108:
	The AT has serial and parallel interfaces on combination
	serial/parallel expansion cards.  Each card has one serial
	and one parallel interface.  You can use up to two cards
	in the system.

From page 111:
	It is limited to three users (because of the AT's
	two-serial-port limitation).
