Anyone ever make there own calc link for a TI calc . I wanna back up my programs and download some from the internet and is there any good programs for making calc apps.

I basically mastered the little basic language, and wanna try some harder programing for my calc. I really want to see how a game is made, somthing simple like black jack at first. I was going to program that but I dont know how I would do the random #s.

Well what else is there to do in chem class, so my calc is my savior. But I made all the simple progs I need as well as an animation of an eye looking back and forth. To bad it's choppy.

Well, basicly im bored, need a link, and better programing to do. Any suggestions?

http://www.ticalc.org/ has lots of programs, as well on guides on making your own links, and overclocking your calc.

I dont know what is wrong with my electronic skills, but I tried making 3 different calc link cables (2 serial and one paralell) and none of them worked. I only spent about $20 for the materials for all of them, but I am still concerned why they didnt work. I ended up getting so frustrated that I ordered the Ti-graph link from TI's website. I would still like to figure out why they didnt work sometime when I have some spare time.
I even had my old electronics instructor look at them and he said I needed more practice soldering but that it should work. Hmm. Oh well.

Spent $5 on parts today. Damn radio shack didn't have exact parts. Got a 330 ohm resistor instead of 300, but with 5% tolerance it should work. My main concern is I had to get a 5.1v diode instead of 4.7v. Well I hope it works, wish me luck

What the heck is NPO capacitor? You need a .1 pf NPO capasitor to overclock the calc. They had .1 pf capacitors but didn't say anything about being NPO Not important though, to much work to install a switch anyway.

I built the cable, it didn't say which way to out the led so I put it neg end going to cal and pos end going to connector. I can't test it though, when I start the software it says "can't open communications port" How can I get the software to work?


Hey, you can barly tell they're homemade!

OK problem fixed, my modem had a conflict with my serial port. My cable doesn't work yet, but the led lights up though.

I never did try my cables after I got my TI-89, but on my 85 the calc would just freeze as soon as I plugged in the cable. Is this same thing happening to you? I will try to get some digital pics of my cables and post them here. I hope you get a cable working, I really want to get this to work, if for nothing other than personal satisfaction.
What calc do you have? The doorsOS for the 89 and 92 is a really good program for running assembly programs under.

I have a ti-83 plus. The calc freezes when its plugged in. I followed the directions exact and the LED lights. Still nothing will work. Well, my brother said at work he can grab me some serial ports and hopefully parallel ports. I might try another style cord.

If anyone here has ever made a calc link that works please tell me what cord it is. I made a copy of the serial "black cord", but it doesn't work.
