However, you will not be able to install this in a II+. The reason is that the CMOS unit is clocked for 4 meg, and the slowest available version still runs at 2 meg. Apple themselves had to modify the bus timing on the IIe to handle the 6502A, because the data windows were already gone by the time the bus tried to accept valid data (hence, the inability to run very time-picky Spiro-disk protected software). As far as I know, there is no version of the II+ (or the 65C02) which is compatible. -Dave Hsu Bitnet: DAVIDHSU @ UMDA ---- end forwarded message -- Uucp: ...!harpo!seismo!umcp-cs!preuss CsNet: preuss.umcp-cs@csnet-relay 301-496-2265
