OS/2 and eComStation In the dawn of the end of IBM's OS/2 Stardock's CEO Brad Wardell pays his respects to the venerable operating system by writing a long article about the history of the OS. Stardock was one of the major third party software houses for OS/2 back in the day and so Brad has lived OS/2 from up close.

hat's like saying Xeons have been out for almost three years so it's a common enough processor... It is and it isn't. Having sold units at the time I can (to the best of my memory) say for a good degree of certanty 486's didn't start really going out the door until '93. Just because the chip came out in '89 doesn't mean anyone was making boards to support them... Even IBM wasn't shipping 486 based machines until November 1990... They were selling PS/2's as their entire product line until 1993 when they 'downscaled' to the PS/1's.

PS/2 model 70-486 came out in 1990
PS/2 model 90 (486-DX) came out in 1990
PS/2 model 95 (496-DX) came out in 1991

As for PS/1's and 2's I think you are forgetting the Ambra line in 1992/3 as well as their more generic line (I've forgotten the name). Further it wasn't just IBM by 1990 you had clone makers that were pretty active.

As for the dates of the operating systems you seen to be agreeing with my dates. The argument is what were the hardware standards. You need to show that memory was uncommon. Now lets take the 8590 for example http://www.can.ibm.com/helpware/8590.html. This supported 8 sockets with up to 8 megs per socket. Thus a standard reasonable config for this system would likely have been 8x4=32 megs of ram. No quesion this was an expensive computer but you are the one who is focusing on the PS/2 line.
