Greetings,

I have a new Z-386/33 system.  I am trying to get an AT&T Targa-32
video-graphics board to work in the 33mhz system (I was previously
using the targa board in an 8mhz AT).  The only way I can get the Targa
board to work now is if I run the Zenith in Slow-PC mode (manual says
15 wait states inserted).  In both Fast mode (0 wait states) and
slow-AT (10 wait states) the targa board will not run.

Anyone know how I can slow the Z-386/33 bus down without slowing down
the CPU and memory?  According to the people I bought the Targa board
from the Targa-32 will not work on a bus faster than 8mhz (actially
something like 8.13mhz).  I've tried putting the Targa board in a
number of different slots with no effect.

With 15 wait states inserted the Z-386/33 is nothing but a very
expensive 8mhz AT.  Sigh..  The Zenith folks were no help, the
support people say they'll call back and don't.  The Sales rep
pointed me towards a third party who could only suggest I buy
the new version of the Targa-16 (not 32) which works on the
faster bus.

Any suggestions?
