Re: A86: asm clock?




In the clock program I wrote, I did use IM 2.  But I could have easily used
IM 1, that doesn't matter.  I just wrote it really quickly to test out the
idea of a clock.  But before we talk about this anymore, I would like to
get one thing straight.

EXACTLY what happens when the calc is turned off?  I don't want to know
what you *think* happens, I want to know what actually happens.  This is
only because of all the rumors going around.  If anyone has dissassembled
the off routine and has a copy, I'd like to see that.

Thanks.
