[comp.sys.ibm.pc.hardware] Testing Hercules-clone video card?

tgl@g.gp.cs.cmu.edu (Tom Lane) (03/12/91)

Can anyone recommend a good method of testing a nominally Hercules-compatible
display adapter card?  I have an Everex display card and am suspicious that
it is not truly 100% Hercules compatible.  Also, it seems to glitch sometimes
when I'm running the PC at 12MHz, but not at 8MHz (this is an AT clone with
adjustable clock speed).
Any ideas on ways of getting more information about these problems would
be appreciated.
