Folks,

I've been burn-in testing my 10 MHz Z100 for about week now and have no
problems (operational) to report.  I had to replace the 150 nSec delay line
with a 100 nSec delay line to get past the power-up self test.  I also strapped
in 3 i/o wait states and set my Z205s to 6 wait states.  I am working on
determining the validity of the ZDS diagnostics as far as the failures
indicated when running 10 MHz are concerned.  The floppy and io port
diagnostics report failures; all others (including winchester) pass multiple
times.  I've repeated them for up to 6 hours.  This is for information only at
this point as I am reluctant to advise that others follow my example until the
reliability of this modification is better known.

On the lighter side....  _PC Magazine_ Benchmark version 4.02 reports floating
point performance of 1.4x an 8.00 MHz PC/AT!!  ACK!

Cheers,

Walt K.
