**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.
