Re: [CAD_CAM_EDM_DRO] Re: Windows Real-time

Art,

I tried the VxD on three other Pentium systems at work this afternoon. They
all worked fine. Must be something funny with the AMDs. I downloaded some
documentation from AMD's website and verified that the K6 does have a TSC.
How much of the VxD is in assembly and how much in C? Do you use only the
TSC or are you also using the 8254?

Regards,

Phil
