I have recently seen an AT clone running at 10mhz, and was quite
impressed at the noticeable improvement in responsiveness under Xenix.
Has anyone *reliably* increased the speed of a genuine IBM AT to
10Mhz?  I am not interested in simply putting in a faster crystal and
hoping that it will work, that the 286 will not overheat, etc.  At a
minimum, I would assume that a certified 10mhz 80286 would be needed.
Also, how fast need the memory be?  I have no idea where to get faster
piggyback chips should they not be fast enough.

I would greatly appreciate hearing from anyone who has succesfully
upgraded an AT to 10Mhz, as well as any reports on reliability
problems.  Sources and prices for the required components would also
be helpful.  I will post a summary to the net.  Thanks.
