investigating port $2F
mrwompwomp:
I got the same result on all 3 that I could find:
TI-84+ rev V OS 2.55MP
TI-84+ rev S 2.55MP
Prototype TI-83+SE VSC 1.18
21845,21845,21845,21845

My tests were made under 2.43 aswell, so i guess that isolates the OS as a variable to explain the difference.
The only explanation i see right now would be that the delay provided by port $2F is somehow relative to the actual CPU speed (not just the CPU speed mode).
However, with what mrwompwomp just posted (see below), i'm not so sure about that anymore.
If i unlock enough time, i might create a different program that reveals which delays your calc uses, i need to know.
Thanks again.
EDIT : Is there a chance ALCDFIX was installed when you ran my program ?

Cool.
21845 (actually 0101010101010101 in binary) is what to expect if the calc uses the exact same delays as on my original post.
That's the numbers i got on my two TI-84+SEs, and the fact that you got the same on both TI-83+SE & TI-84+ is great progress.
Thanks a lot !

I believe so.

Your port $2A doesn't probably hold its default value then, which could explain everything.
Could you please confirm that for me ? (Calcsys - port monitor, or attached program)
