PS/2 Keyboards for Calculators
Posted by Eric on 3 December 2001, 01:15 GMT

Cullen Logan has written a technical document on something I've personally been interested in for a long time: using a regular PS/2 keyboard for a TI calculator (drivers are released for the TI-86; a TI-89 version is on its way). It's a good read for you technical types out there; basic schematics are now posted as well. Hopefully the ball will start to roll on this one...

Update (Nick B.): The ball has indeed started to roll, as it has been ported to the 83+ Silver Edition by Radical Software.

I just have a few things to say.
1. everything from the ti-89 and ap, is fantastically required if u want to be good at math and chemistry.
2. It has a great selection of games
3. EvilDead and army of darkness are fantastic movies.
4. From personal experiance and my opinion, the ti83/+ is a piece of trash.(remember my opinion)
5. Hemp makes a strong rope.
6. any game made with the name rainbow 6 in it is God, and nothing will change my mind of that.



:::The reason i did this was i was in a ti83sdk forum onthis site and say some distasteful comments toward me, my 89, and the evil dead movies. And i have a message to these and only these people. F&@K OFF!!!

Sorry, but you're a sick and obscessed person! Why do you always have to bug everyone with your Evil Dead stuff? You've already stated your opinion about hundred times and don't have to do it anymore.

It's everyones God given right to say what they think, not just yours. And if you hate 83+'s so dad, why were you reading a TI 83+ SDK forum in the first place? And why do you see it necessary to waste our time reading your retalliation (which would have made no sense without that brief explanation) here instead of where it belonged (where it would have made perfect sense anyway)?

Why anyone who thinks defending BinLaden is wrong no matter what they think.

"Have people yet to learn that defending the Afghanis is not going to bring anything to them but disdain?

I dont know what country you are from, but they probably hate you anyway. Can you understand that? When I hear that there is a group of people who consider killing inoccent people in other countries a GOOD thing, all I can do is follow my first rule of life:

There can be no problems if you eliminate the source of the problems.

Hence, we bomb them to Hell. We never let up. We reestablish a new government there (hopefully democratic so the littl bastards can be under our thumb...gotta love capitalism!) Then voila! We have screwed them up and the easiest way to make a bad dog be good is with a smack. This is our equivalent of a smack.

The people in this argument that think the U.S. is wrong by bombing the "helpless" Afghans obviously didn't lose anyone close to them on Sept. 11th. I too (like AlexRain) am from New York and have lost 2 friends to the attacks. Can you imagine what I'd feel like if my Government didn't do anything? The American people were SCREAMING for a month about how we weren't doing anything. Points I'd like to make:

1 - The reason we are bombing these scumbags is because they are harboring a terrorist which has performed multiple terrorist attacks on the U.S. (U.S. Cole, Kenyan Embassies) after they were warned for over a month.

2 - The major attack (WTC) was on CIVILIANS!!

3 - Any individual that follows a religion that says you should slaughter people because they are evil are just weak minded people who should die first. Didn't the world learn from World War II?

4 - And speaking of World War II, the WHOLE world owes the U.S. for saving them from that monster Hitler. If you think the Allies would have won without the U.S. you're crazy.

5 - Someone had meantioned that we used Nuclear weapons. Do you know how many lives were saved by dropping the bomb during WWII?

6 - NO COUNTRY IN THE WORLD IS SAFE FROM THIS MONSTER.

7 - I do not believe in killing civilians, but if it brings that monster to justice, then I can live with the fact that there are going to be civilian casualties. Do you honestly think the U.S. is purposely trying to bomb civilians? Get real people.

I would love world peace, harmony, and freedom for all, but unfortunately there is too much evil in the world. The U.S. has always tried to help other nations and all we get is grief in return.

WHAT OTHER COUNTRY WOULD BOMB A GOVERNMENT (NON-RECOGNIZED) AND THEN SEND FOOD TO IT'S PEOPLE? GOD BLESS AMERICA!! THE WORLD OWES YOU!!

You seem to forget, that it was the Russians who invaded Berlin in April 1945. The Allies would have won even without the aid from America. Sure, it would have taken longer, but they would have won. If you can't realize that, you're crazy....

Honestly, I disagree. Hitler's army had nearly reached Moscow when the US entered the war, and Hitler had to divert forces from his eastern front to his southern and northern fronts to hold us off, giving the Soviets (at that time they were Soviets, not Russians) the ability to slowly force the Nazis back to Berlin.

Also, in regards to 3- above, Islam does not condone slaughtering individuals, even those non-believers off Islam.

In regards to 5- above, I agree. The Japanese were willing to fight to the last man and the expected casualties were 1E6 (this is a calculator site) Americans and 100% Japanese.

Right. I know several Muslims personally, and have had discussions with them on the subject.

Hitler was doomed the minute he attacked Stalin. There is no way he could have defeated both the UK and the USSR. But that has always been the problem for Germany. They're right in the middle of things and it's quite difficult to defend Germany.
Also, the Germans were being fought back by the Soviets (you're right) in the winter of 1943 before the Allies invaded Sicily in July 1943 and Normandy 1944. I agree that that the whole thing went faster because of the US but it also went faster because of the UK and the USSR and because of Hitlers failure as a strategist. I don't think the world "owes" the US anymore than we "owe" the UK or the USSR. In fact, the USSR was the contry with most casualties so if anyone did a great thing for the world, it was the soviets. Just too bad they don't have a Hollywood of their own to tell of the heroic acts by the soviet soldiers...

Does this have anything to do with calculators? Don't start talking politics here.

Don't you understand that you are enticing me to react, jeez that's as dumb as Bin Laden bombing the US and not expecting a war, o wait is that it, do u like to fight, do u want a war, or is it that I want to fight, or we both do (knowone forced you to respond to that post).

Wow what an interesting concept, we all want to fight each other just for the sake of fighting. Its like the thing that makes all humans evil with the strong desire to cause pain. For instance Lord of the Flies, or better yet The Island of Dr. Moreau. Look at the poor doctor, trying to remove the evil from the animals so that the same technology could be used on humans, and everyone thinks of him as a monster. I personally think that to be an honorable cause. To remove the DNA that makes us want to commit malice acts, and I bet people with the means to do this research probably are.

I wonder how you and everyone else would respond to this post. Would people agree with me? Would you just prove my point, and further expose mans evil? Or would you try to bend the facts to make me look bad? Or would you not post anything being that I got you blocked from every vantage, and theres no way your getting up from this? It's almost comical-to watch you struggle, because I can guarantee that you'll return to see what kind of effect your post had on me, I laugh out LOUD :)

Who is the animal, we all are, but we're to ignorant to see this...Well I see it.

There actually is a movie called Evil Dead, you know. And it *is* the greatest movie ever made. It's a simply horrible horror movie. The plot is empty, the characters flat, and the blood as copious as snow in an arctic blizzard.

Is it common practice for calc coders to have pay pal links on their sites for donations?

/me remembers the good ol' days when we didn't care about that ;-) of course .. we were also 15 and living with our parents ..

The paypal is for them selling graph links I believe.

So what appened to the acz?

Topic Specific: The 89/92+ has an interesting feature whereby fake key presses can be sent in through the link port and the calc will respond as if they were pressed, so if the hw can send these codes then no on calc driver is needed.

This is what the keyboard by dba.ticalc.org does.
And if you want to play around with feature on the calc with vti then there is a program called remote control by Greg Dietsche: www.geocities.com/gdietsche

The ACZ died about a year ago. I've actually managed to meet one of their ex-members. He goes to Michigan Tech, and I sit next to him in my Java class... (little pun there, if you can catch it). He said that they pretty much drifted apart because they didn't have the free time to do what they wanted to anymore. Basically, it was because they either went to college or started doing their homework.

Pretty much. It's more fun to write code than to maintain a website :)

Actually, *ALL* TI calculators with linkports have that capability. This includes (for example) the TI-85,86,83,83+,89,92,92+, etc...

Only the ones with silent linking capability can do this. That means 83(+(SE)), 86, 89, and 92(+). The others cannot recieve data let alone keycodes without setting them into "Recieve" mode.

On a completely different topic, has anyone ever tried making a link emulator for a calc? What I mean by 'link emulator' is a program on calc A that lets it use the linking protocol of calc B. E.g.: if I have an 86 and an 83+SE with 86 link emulation, I could back up my 86's data on the 83 and then retrieve it with no special program on the 86. I think that this would be _very_ useful after a memory wipe or "crash."

Crash is sort of a misnomer for this, though because the usual meaning of crash that I encounter has to do with physicaly impacting multiple things such as a drive head and the disk it is reading. TIs have no moving parts, so they cannot crash in this sense. Why do we say this?
