**Spelling errors/mistyped words
Yes, I  know there are  spelling errors,  and things are  mistyped. It
seems no matter  how hard I try  my fingers hit 't'  twice when typing
'compatible' rendering it 'compattible' numerous, (thousands actually)
times.  I  don't have the  time or the will  to check the  spelling of
everything. Basic spell checking has been peformed. Please let me know
if  there is  anything that  would lead  to incorrect  information, or
something  is so  mangled  that  it needs  revising.  But  if you  can
basically  understand  what was  intended,  just  cope with  it.  Just
cope:-)

BTW, "110" port is  an "I/O" port that has been OCRed  badly, as is an
"1/0" port.

**82495DX/490DX DX CPU-Cache Chip Set                           <Sep91
***Notes:
date source: none direct, however:
InfoWorld Jan 20, 1992 p98 - Compaq Deskpro 486/50L 
mentions it has this chip
Network World Sep 2, 1991 p20 - Advert for new Compaq Deskpro 486/50L
mentions 256K cache
so assumed to be sometime before sept 1991.
