Ok, I've made some tests with 20 TI-83+ 512K ROMs:

- the 10 OS I've got (1.03, 1.10, 1.12, 1.13, 1.14, 1.15, 1.16, 1.17, 1.18, 1.19)
- combined with the 2 Boot Codes I've got (1.00, 1.01)

In all cases, the emulator is booting correctly.


So congratulations for the compatibility!


I also tried to use some very similar TI-73 512K ROMs, but it hasn't worked up to now.

I'm happy to hear that.

Btw: Anyone deleted my post? That was not meant to sound sarcastic...

Seriously, this adds much more value to all 83+/84+ Projects(!)

nice to hear it boots fine critor!

@lolje, nope, none of your posts were deleted, because I checked the trash bin forum (invisible to everyone but admins) and I saw none of your post there. Unless Eeems did it but it's less likely because he knows I don't want posts to be deleted (except adult/warez stuff)

Any new progress on this? Maybe a alpha release?
I wonder whether TI likes this or not.

Mhmm idk if they will take any action if we do not redistribute the ROM images. I think Calc84maniac is planning to do what WabbitEmu, Em8x and VTI authors did: require the user to get a ROM himself to emulate the calc.

I am curious about progress too, altough I think Calc84 is busy with the Mario game for the 84+ ATM.

Maybe if he uses benjamin's 3rd party boot code for z80 calcs and just send a upgrade file downloaded from education.ti. Hmm, I don't know if this actually works, I am not an expert.

Hey, calc84maniac, when you say you can't figure out how to write to the nspire's link port, what do you mean? is it a problem with the addressing, or is it more complex? Hackspire has the memory location of the 84 link port listed.

If I remember, even BrandonW and other people like ExtendeD haven't figured out either.
* DJ Omnimaga wonders if that stuff is possible to access through Ndless

I was wondering that myself. Maybe someday we'll have Ztetris for Nspire and be able to link it with any other TI calc. =)

This is true. However, writing to the port does not appear to have any affect on the link cord lines. I assume it must need to be activated somehow.

I wonder how much use it would have if you cannot link the calc, though. (assuming you are requesting a copy of the z80 emu for the TI-Nspire)

Another concern I have is if the speed is not 100% accurate (example, if it's 99.999% accurate), would linking with a real 83+/84+ or a computer fail, anyway?

There's generally a small amount of tolerance, and at least TiLP will allow you to configure values. If it's too far off, though, other calculators and TI-Connect probably won't be able to handle it.
(Btw, 99.999% is a deviation of only ~60Hz on an 83+, which is very normal and can be created by simply using older/newer batteries)
