This caught my eye.  I nearly always run the clock display.  (Only when
archiving and when CHIP doesn't want to run from a program do I turn it
off.)  {I've a short prog that turns the clock off if it is on, PROMPTs the
user to hit CONTinue, calls CHIP, and then re set's the clock flag if it
was set in the 1st place.  The PROMPT or a HALT is required to turn off the
interupt, or the emulator suffers a performance drop.}

This brings up another point I was thinking of making.  When I first read
the CHIP docs, I assumed that the clock problem was that even after the
flag was cleared, the clock display remained until the current prog exited.
My experience encasing CHIP in calling routine suggests that the actual
problem is that the interupt remains on, degrading CHIP's performance.  I
wonder if there are any wispered hints floating around that might alleviate
that problem??? (HINT HINT HINT ;^) )
