Cool! 😀

Thanks, yeah I just couldn't believe my dumb luck in getting one blindly that had already been modified to do what I wanted it to do. 🤣
I just had to show you guys. 😜

Very nice. Loving the retro clock btw 😀

🤣 thanks. That was a goodwill find, I fell in love with it right away. Plus it was only 2$ so that helped seal the deal. 😜
It's about the only thing that can get me up in the morning, rather than beep it makes this god awful grinding noise. 🤣

The IBM PCjr joystick is best suited to arcade games it seems. It's sensitivity isn't the greatest and it tends to wing you around. 🤣
I think this could be partially fixed by getting softer centering springs (since you kind of have to wrestle the thing) but it's mainly due to it's method of registering movement.

I wonder which came first, the PCjr Joystick, or the Tandy version?

The Tandy was more or less a copy of the PCjr, so I would guess the PCjr joysticks came first. At least I am pretty sure the joysticks were available upon release.

Yeah the PCjr's joystick came first, this is a pretty common joystick though since Kraft also made some that were identical. I could have used one of those but I like having the IBM logo on it. I imagine they are exactly the same internally though.

I would also like to tack on this bit of info for anyone wishing to convert one of these joysticks. Here is how he did it basically, I'm quite impressed by how neat and tidy this mod is.

So simple a child could do it, but first someone had to think of it. 😜

Pinout for the Gameport. I've even gone and colour coded the diagram for quick reference. All you should care about for this mod are pins 1-7.
I should mention that Blue is that silver cable shielding stuff, it's a ground basically.

I disagree, because the joysticks for the Tandy 1000 are the the same ones that Tandy used for the Color Computer, which came out in 1980.

Yeah, I meant the TRS-80, not the Tandy 1000.

Edit: Formatting.

Oh 🤣. Well there you go. Tandy had the joystick first, it seems IBM and tandy borrowed from each other quite a bit then. 😜

Tandy joysticks are not exactly the same as PC or PCjr. joysticks internally. Tandy sticks connect the third terminal of each potentiometer to ground so that the pot functions as a voltage divider, IBM sticks leave the terminal unconnected so the pot functions as a variable resistor. Its simple to change to the other type.

Is there a difference in sensitivity? Because the PCjr joystick is pretty all or none when it comes to directional movement.
