That was a safeguard to prevent memory errors while assembling. Then when they made it so you could transfer stuff off your computer to your calc, they didnt bother to remove the limitation. Duh.

No. What follows IS the correct reason:

They blocked execution on RAM page 0 ($C000-$FFFF), or even pages on the SE/84+/SE, because if not you COULD just copy the code from an app and make some slight address adjustments...

I've successfully copied an APP to run from a RAM page on a TI83+SE. The only problem was that it couldn't bcall to a different page due to a restriction in BCALL itself! It could use romcalls fine. Any 16k app can be put in ram and run from there. You could even compress it first, then decompress it into ram. Has to be a silver edition since that has extended RAM which can be placed into the page usually used for apps.

Yes, but most people arent ASM wizards.

Well the pirating of APPs has always been the obvious and accepted answer, but its not like TI have actually confirmed it. Would be good to know for sure

Of course, but it takes only one person to break a protection and distribute the result, and that's enough for the 'naive users'.

I asked Mikey Milheron today and he said that his dad was lazy and he would ask his dad to try to answer them tonight. No garauntees though.

FINALLY met him (in person) and he said to type up the questions again and email them to him. Last chance to add a question.

And that person would be Michael Vincent
