I first use the 80186 on a Unisys B26 workstation (See link <http://www.geocities.com/SiliconValley/Pines/4011/faq/CtosFaqOct1999.ht m#4.1)%20NGEN%20(B-Series)> ).
It was a great machine with a message based OS way ahead of it's time. -----Original Message----- From: Neven MacEwan [mailto:[EMAIL PROTECTED] Sent: Thursday, 16 September 2004 7:52 a.m. To: NZ Borland Developers Group - Delphi List Subject: Re: [DUG] ShortInt, SmallInt Yes Novell Dedicated Servers used the 186 Neven MacEwan (B.E.
