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. -- Larry Pajakowski Extel Corp, Northbrook, IL ihnp4!tellab1|extel|larry

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. -- ------------------------------------------------------------------------ C. J.

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). -- Mike Brown ...pur-ee!pucc-h:ad3
