Hey all,
    Just a note to add to Greg's.  About 6 years ago it became known that one
could take a crystal that was supposed to go in a 500 and place it in a 400.
This crystal, of course, ran at 14 Mhz and was a significant boost to the 400.
Now, sometimes this did not work.  There would be problems with the memory, the
clock, etc....  In these cases the 400 required a new chip set also.

    In my case, my 3B2/400 ran fine with just the crystal.  Wether or not a
400 needs just the crystal or both the crystal and the chip set is fairly
arbitrary.  We were told to use trial and error.  IE.  Buy the crystal first
and then if necessary, get the chip set.  The crystal was purchased from a
reseller who purchased it from AT&T themselves.  It was not a "kit", it was
just a crystal.


Hope this helps,
    Steve.....
