Yepp, this was a pretty nice piece of work. Though, it had to be pretty thorough to fool some of the people that it did.

I made one mistake and critor found it. I didn't add an extra little bit to the OS that TI usually does.

we need zstart for the CSE!

* Sorunome pokes thepenguin

Not a chance. (At least not by me) I hardly have enough time to update zStart let alone make a new one. And besides, I don't have a CSE.

False

Actually it would probably be something like OS 4.16MP

If Output/Disp were so slow in 2.71MP, imagine how they would be in a color version of that OS.


Also the HP Prime is as unstable as 2.71MP when you try to edit a 400+ KB program

What was it ?

It was the signing, I believe.

It was indeed. For whatever reason, after TI signs the OS they add "   -- CONVERT 2.6 --" at the very end. I forgot to do this.

LOL you'd actually have to look with an hex editor for this one.

Actually, you don't. Try opening an OS with notepad and you'll see what I mean. (.8xp files are binary though)

I just realized something... this "OS" is actually better than TI-Nspire CX OSes in one way


On OS 2.71MP, you can still run small ASM Flash apps from 15 years ago. Yet, on the TI-Nspire CX, most programs will stop working 1 or 2 OS versions later. On the HP Prime it's even worse because some programs like MacBernick's game only lasted 1 firmware and on Casio calcs they won't even last accross hardware revisions.

And if go back 1 version earlier (2.55MP), then you can pretty much run anything from the past 15 years, even smaller TI-82 Stats/83 BASIC programs and if TI-Connect allows it, TI-82 programs by renaming the extension like in the TI-Graph Link days.

I remember in 2004 when I downloaded many TI-82 BASIC games, renamed the extensions from 82p to 8xp (or maybe it was 83p?) then sending them using to my TI-83 Plus Silver Edition using TI-Graph Link and it worked like a charm. I don't know if that trick still works with TI-Connect and TiLP so perhaps this rules out USB calcs, but if it does, then even programs from 20 years ago would send and run.

It's a shame that they can no longer keep compatibility intact when updating OSes nowadays. A lot of work gets wasted that way if the authors of programs move on in their lives.
