I have a routine that I have written in assembler that has 838nS resolution.
The routine uses the 8254 timer chip in the PC.  The routine was originally
published in 02/87 Byte magazine (I think 02/87).  If you can't find the
article in the library, or are still frustrated, I will send you a copy of my
code.  I have adapted it for various uses, including calculating CPU speed.
