By a shell, I mean program launcher, and not a kernel- and not this.

I was talking to qazz42 on #cemetech (helping him with his new TI-89 Titanium) and he asked what shell I liked the best. Now, I don't use one at present, but I am fed up with VAR-LINK, and I was wondering what people who have an 89 think is the best one?

I personally think Einstein is cool (sort of like DoorsCS for the 89) except it's in French.

PCTools is also cool, but it's a kernel program. And it's quite possibly the only kernel program I've wanted to run thus far- which is why I use KerNO and not PreOS.

So, I would prefer to use a nostub shell- but if there's nothing very good I'll use a kernel one...

Titanium compatibility is a plus too.  

Einstein just causes my calc to freeze on " Line 111 emmulator"


what do I do?

bah, ok then

btw, I plan to install preOS later

I got super mario 68K working

I personally just prefered to run all my ASM/C programs through VAR-LINK and home screen, no shell/kernel program.

Btw what's the difference between a shell and a kernel, in terms of calculators?

On 68k calcs there are two different things- shells, and kernels. Well, and "KerNO"s, but there's only one of those.

A kernel extends the AMS allowing it to execute "kernel" programs- programs compiled to use the kernel libraries.

A shell is a file browser. Some shells are nostub, others require a kernel.

KerNO is like a kernel in that it extends the AMS, but does not provide crash protection.

On z80 calcs, shells and kernels seem to be the thing. Ion, MirageOS, DoorsCS, CrunchyOS, etc... all of these are (from a 68k perspective) kernels that contain a file browser.

The Ultimate FAQ explains it pretty well (the 68k section) except it's a little out of date.

I thought that KerNO and preOS had crash protection...

anywho, I decided to stick with preOS

it DOES have awsome games

preOS has in-built anti-crash stuff...

If you download games from the "Assembly Games" section on ticalc.org, they will invariably work without a kernel (but some might require a library, like the FAT Engine). You need to go to Assembly Games\Kernel to get Kernel games.

Ghostbuster is a patcher, that patches programs to be more likely to be compatible with the Titanium. (More likely because it only fixes the most common issues). PreOS is a kernel with crash protection, KerNO is a TSR also with crash protection.

And yeah, unfortunately there aren't a lot of TI-89 RPGs... there is this unfinished RPG, turned RPG engine, which looked interesting... if I ever actually make a game, I was considering giving it a try.

I still want to know what "line 1111 emulator" meant...

It's a common assembly error- I don't know what it actually means, though.

Unlike the TI-83+, where errors like this automatically clear RAM, the TI-89 preserves it's state and makes you do it manually.

One of the things KerNO does for you is intercepts these errors and prints them in a dialog box on the screen. (PreOS I think prints a "Crash intercepted" message to the status bar instead). But you should reset RAM afterwards, as your calc is probably in an unstable state.
