And do you remember XGA it is also standard for PS/2
eXtended graphic adapter - haha. Other name was also funny
PC XT - extended technology
PC AT - advanced technology. Oh my first 286 with 16 Mhz and 1 Mb ram with monochromatic (black orange) monitor.
And you are right that PC/2 could be a pretty good standard. But such a fucking IBM wanted to only sell this standard, not free like a XT or AT. By the way I heard that only one think was licenced in XT standard the BIOS. And Copaq was first company wich cracked it and cloned it.
It was possible because, about year 1979 IBM managers found out, that IBM is only one big player (in computer bussines) who doesnt have personal computer (PC) - other words computer which can buy person for his or her self. IBM was hurry, They decided construct new computer as fast as they can (to year 1981). Only one solusion was possible - buy existing products and didnt develop its.
That is why:
proccesor form Intel
OS from microsoft
and so on, and so on
But i know that was the biiiiiiiiiiig lucky for open PC platform. And why is PC the most wide-spread platform. And why is soooooooooo cheeeeeep.
hehe
