I don't know how many people are aware of this, because it was brought up here in 2004 and then dismissed by ArcaneWizard, but apparently someone made a TI-83 (not Plus) emulator in Java. I think this is kind of cool, because it provides a way for people to mess around with the calculator and games or programs from ticalc.org without having to mess around with ROM files (since the ROM file would be hosted on the server and inaccessable to the user, which I'm pretty sure makes it legal).
Here's where I found it: http://www.df.lth.se/~lft/entertainment/stranded/
I've decompiled the source, and it looks like it's a real emulator, although it's at least partially customized for the particular game it's hosting. Maybe someone (shot not) would be interested in contacting the author about permission to modify it to be a more full, generic emulator, and add archive support so that it can work with the plus series? (S)he might even have the source code lying around, which would be nice, because although Java is one of the better (best?) languages to decompile, since it preserves variable names and stuff, it obviously doesn't preserve comments...
Anyway, even if nothing happens with this, I thought it was a pretty cool idea. Could you imagine if ticalc.org gave the option of testing programs and games right in your browser, before even downloading them? It would be pretty handy, since I hate digging out my own calculator, or even finding where I dumped an emulator and rom files on my hard drive. |

| Unfortunately, Java applets are downloaded and run on the client, not the server, so ROM distribution is still a problem. |

Maybe if we modify it to use server-side java scripting, and just feed keyboard input and video output via an applet... |

What a really cool and amazing idea. Too bad it hasn't passed legal issues yet.
If ticalc accepted such idea, surely more programs would be run. Yet rest to know on calculator or not.  Restricting to 10 minutes of use of emulator would be greedy... |

| hmm, but if everyone had access to the ti-calculators online, even if they didn't have the rom, wouldn't that kind of defeat the purpose ti did restrict rom distribution? |

| TI defeated it themselves when they provided the Flash Debugger for free with clc files (essentially roms) |

You could use RMI (Remote Method Invocation). |

Not sure it's a problem in that case.
The emulator doesn't seem to include/load any ROM file. |

Necro? :|
Anyway, do we know who Linus Akesson is? If he's still around maybe we could borrow his source and make a real online emulator. It would still need a ROM, but having an online calc would still be cool.
Or maybe one in Flash? I know there's another emulator out there (don't know the URL) that does non-flashed Z80 calcs (requiring a ROM). It might be a big jump to add the flash support, but at least all the Z80 opcodes are already emulated pretty well.
