My old 8088 ran at 10MHz, but I do believe there was an 8MHz variety too. 4.77MHz was common at the beginning too. Intel also licensed the technology to NEC to have them fab some chips too, but NEC took the design and optimized it and came out with the NEC V20, a direct drop in replacement that was supposed to give 12MHz worth of performance without changing the clockgen on the board from the original 10MHz one.. heh.. Ahhh the good old days.. I ran a BBS on my old 8088 for awhile.. Man that sucked.
