pat,

sorry to keep bugging you, but i have a few questions...

4) is there a standard address for the calc's off routine (when [2nd] +
[ON] is pressed) on all versions of the 83's rom? if so, what is the
address?

5) what is the address of the apd counter, and is it a byte or a word?

6) is the calc shut off when the apd counter reaches 0?


i want to know because i want to catch the calc before it apd's and just
shut it off normally, so the apd buffer won't be altered (i know it can
be done because i saw it on the 82).

btw, out of curiosity, did you work on any other calc's?

thanks!
