) on the
"mainframe"; with a 60hz (presumably line) clock on the micro.

If you are connected over TELENET, the delay will typically by
much less than 1 second. At the moment, I am logged in to a PRIME
system from a TELENET PAD, and I have apparently-real-time command
execution. I.e. less than 200 milliseconds.

I suggest that the micro request time from the host mainframe, and
then subtract (about) 0.4 seconds. This will certainly give results
at least as accurate as the (postulated) 1 second mainframe clock.
