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.
