"Hunky-dory"

Gee Nick, nice choice of words. :)

Oh and this is cool too... even though my 89 is HW1 and I'm never putting 2.03 on it, unless they port every game. 700k isn't worth it to me with nothing to put in it.

For hv 1.0 you don't get 700k, you don't get any more user-accesible memory. flash apps go in the space between 380-700k, so all you get is archive retention and a slightly better shell.

Yea... that too.

- Jeff

Let me get some things straight : I have a TI-89 hw1 (hw1 calcs do not display the hardware version in the about screen, right?) with AMS 2.03.
a) I don't get 700kb of ram, archive or otherwise?
Then why does my mem screen say Flash ROM free 720884? Do I not get to use the area from 380kb to 700kb except for flash apps?
b) What is this "software limit" on the memory? AMS 2.03 on my hw1 calc seems to be great, I can play games just fine, except for the rare crash.
c) What is with the archived RAM buisness? I have a chance of archive mem recovery?
d) Do hardware version 2 calcs get to use the extra RAM? If so, why can't hw1 calcs use the RAM

I guaruntee eternal life to anyone who can answer my questions.

I don't no if I really want eternal life but I can answer some of you're questions.
I don't no if HW 1.00 calcs have the version in the about menu. I have a TI-92+ with HW 2.00.
A)Correct, I know it's stupid, I did the same thing so now i can't run ASM programs.
B)Software limit doesn't allow ASM programs over 8k to be ran. Another stupid thing that can't be fixed on my TI-92+ because of HW 2.00.
C)If you have anything archived and your calc crashes if you reset it (not taking out the batteries) you an recover it, but don't ask me how.
D)No. Well only for flash apps.
If you have any other questions please e-mail me.

P.S. I'm pretty sure i don't want eternal life, but thanks anyway.

HW1 calcs don't say their hardware version in the about screen.
For HW1 AMS 2.03 calcs, the extra archive memory (about half of it) only works for flashapps. HW 2 calcs can use all of the memory for anything.
The 'software limit' on memory is why HW 1 calcs have only half of the archive to store programs and data.
In AMS 2.03, after a crash or mem reset, the archive memory is restored. I have heard of cases were it did not compleatly work, but that has not happend to me.

This sounds cool but how was it done?

Huh... it can't be explained in one or two sentences.
You need to know a lot of HW2 and AMS2.03 to understand how Julien breaked the protection. It is terribly dirty trick.

so what was the dirty little trick?
why ya'll jumpin around like that

The trick IS "dirty" but NOT "little". Even the explanation of the basic idea only would take a whole page of text...

btw, awesome work Julien, it is only a matter of time before we start manufacturing our own TI's that come with our choice of Universal OS, DoorsOS built in:P

YEAH!! I got it to work... somehow phoenix doesn't work though, it just freezes... anyway i have a question: which is better, universalos or doorsos?

I think doors os is better; I actually got it running on a hw2 calc (uos ran, but it kept giving my friend "memory" errors, even though he had 90% of his ram free)

does universal os have an interface like doors or is just a kernel?

I think you have to use a "third party shell" as the uos readme says

i dont know if this will work though.... can i use doors explorer after installing uos? will that cause any problems?

well, it should be allowed, it IS (at least, stated) fully compatible with doorsos; I don't think the shift+on shortcut to doors works though, correct me if I'm wrong

never mind about phoenix... it works on doorsos.

He defeats the 8k limit huh? sounds like a boxing match. sounds....epic.

I could have used "HW2 Limit KO'ed by Julien Muchembled"... ;)
