The new Zenith PC-compatibles (the Z-138, Z-148, and Z-158) offer a
switch to allow them to be operated at 4.77 MHz and 8 MHz.  If you
intend to use an 8087 math chip with one of these computers, you
will need to get an 8087-2, otherwise it may have problems at the
higher speed.  Note, by the way, that a Z-158 at 8 MHz will outrun an
IBM PC AT for a number of jobs, especially those that are floating point
intensive.  (An 80287 in a PC-AT runs at just 4 MHz, making the AT
no faster than a PC for floating-point-computation-bound tasks.)
