[comp.os.cpm] New Z-80 Chips --> Upgrade?

SABAHE@MACALSTR.EDU ("Arun Baheti ") (11/21/90)

After seeing the notice regarding the latest 20mhz z-80 chips, I
am curious to find out if anyone has successfully upgraded their
Xerox 820-II or Xerox 16/8 to the higher speed chips?  Does anyone
have any information or pointers?
