I'm thinking about connecting a microcontroller w/ADC to a TI-86 through the link port, possibly eventually making a full data acquisition unit (DAQ). If I ever get it done, I'll upload it to the Hardware Schematics and Plans section.

No one's going to read this, but I finally started work on it.

50 Mhz single-channel oscilliscope/25 Mhz dual-channel
8-13 DVM channels
A few digital pulse/frequency measurement inputs

So darn hard to find a high-speed ADC in a package that I can solder easily...

Hello. I'm thinking of a microcontroller to communicate an TI Voyage 200 to plot results and data processing. Do you have any info about how to use the O/I port or the accesory port of any TI Calc?

Regards

I've designed an internal RTC (real-time clock) that would connect to the linkport of a calc. Once I write the drivers, build it, and work out the bugs, I'll upload the schematics and software to the hardware schematics and plans section.

It's me yet again! I'm writing a program that would allow you to control just about every customizable aspect of your TI-86. It will show sqrt progs, user routines, graph settings, homescreen settings, and many other things such as cursor flash and APD. I expect it to be done in a few months.

I've completed the memory and homescreen menus-graph menu coming up next!

Graph menu and text menu completed too. On to the user-routines menu.

Everything done!-except for displaying the amount of free and used memory. Does anyone know of a good routine to display ahl in the variable-width font?

Never mind-I found it at $3d0a in the ROM after much hacking with VTI.

I'll need some beta testers-I found the call in the ROM, so it might be specific to ROM version 1.6-I'll need to find out if it is.

I'll beta-test for you. BTW, have you stopped working on you pretty print for the 86? I haven't been able to find out why it doesn't work, and I was wondering if you had made any progress.

That would be great! I'll e-mail the program to you as soon as I can. I am still working on the pretty print program, and have about a third of it working (I write more of the code for it when I'm not working on complete system manager, dark forest, PCref, LogV, Divis, Cmath, etc.).

Just decided......I'm going to add security features, such as a password when you turn on the calculator, a locked link menu, and a memory menu that would either be locked, or would do a fake memory reset and make the delete menu appear blank. This is my first time using (sqrt)Key programs, so it might take a while.

I'm designing an external backup module for the TI-86. It would use the silent link protocol for sending and recieving files, so it wouldn't require any drivers on the calculator. Just press a button once for creating a backup, and again to restore the memory. It will probably be about 3"x3"x1" in size.

*submitted*, hopefully will be available soon.

If you don't know what brainfuck is, then you should find out ;) This is yet another brainfuck interpreter, this time for the TI-86.

enjoy.

If you don't know what brainf*** is, then you should find out ;) This is yet another brainf*** interpreter, this time for the TI-86. Revision 0.8, stable.

I'm finally almost finished with KeyRef 2.0, which displays key signatures, relative keys, and now, updated from version 1.1, music theory information about forming chords, scales, and more.

Just uploaded tonight!! That means that it'll probably be about another month before it gets into the archives. ;)

BTW, I realized that I've posted _most_ of the last page or two of comments....shows how little of a life I have.....besides listening to Bon Jovi.

Well, it's in the archives. An '83+ version should be in there soon, too (I've uploaded it already). BTW, look at the cool disappearing subject bar!

I am working on a encryption algorithm,(automatic generated key & a manualy typed key) does anyone like to try to decrypt the encoded message? It will give me an idea on how secure the software is.

I would like to if I didn't have so many other projects.....sorry.

OK, sorry, I realized that that comment was pointless.
