[comp.sys.mac.system] It says 8 but it's really 6

Sorry about the bandwidth, but this note is to prevent further
misunderstandings...

In my post about the slowness of 7.0b4 I mentioned that the Mac Plus runs at
6 MHz.  I know all the literature says 8 MHz, but actually the clock ticks at
7.66 MHz or something like that.  But the Plus has some unusual hardware in its
innards so, as Inside Macintosh Vol III (I believe) says, on the Mac Plus you
get an average access rate to the memory of 6 MHz or so.  This is why Apple can
say the SE runs 25% faster than a Plus even though they have the same clock
rate.  So there. :-)
