Off the Shelf Trackball Options

[charmless]

I really want to pick up a trackball to use with Mister and Mame. I am having a hard time finding one on the used market. So, would something like a Kensington trackball work well? https://www.kensington.com/p/products/e ... ackball-3/

[XtraSmiley]

If you're going for a computer one, I would think bigger is better, like:

or

But I would stick with an arcade made one.

I was looking at this Couchcade and thinking it could be an easy mod to make into a wired USB controller with a £20 interface board. (Future EDIT, it is not.)

Computer trackballs aren't really a great substitute for an arcade trackball.

[charmless]

Thanks for all the answers. Looks like I am staying clear of Computer trackballs. The Couchecade option is tempting.

I tried the Kensington trackball way, and it works. The Kensington trackball is seen as a normal USB Mouse, and works as a mouse. But, it's like controlling a marble, rather than a trackball - it does work well enough.
The Atari Couchcade is a bit cumbersome, and has a rather large footprint - worse if you sit at a table/desk for your Mister because the couchcade takes up sooooo much room, it's even larger than my Hori Real Arcade Stick. and, you have to hope it has wiring that is compatible with a USB controller - but, you need a USB controller that has trackball support. Something like an Ultimarc IPAC 2 will support trackball, joystick, buttons, and even a spinner, all on one controller. The couchcade's main problem is that it is wireless, it uses a separate little wireless box to connect to the TV, and couchcade.

I am going to try a different route, and try to see if one of these can be modded/wired to an Ultimarc IPAC 2.

I have two of these, and the size is perfect for Mister use. The trackball is a little stiff, so may need some modding there. The buttons are smaller than normal 28/30mm, but they click, and feel ok. There might even be room for a spinner by drilling a 30mm hole underneath the Left and Right buttons.

Actually I seem to remember that Arcade1up needs it's own interface to connect their spinners. So it might be more difficult than I was thinking.

I'll be interested in see how you get on with this. I got hold of a PSX trackball with an idea to convert it to USB, but the mechanics were reversed to the
ball mouse I was going to strip of it's sensors.

Here are some pics of the insides. I guess, like the Couchcade trackball + spinner, all you really need is access to wiring of X and Y (both directions), Ground, and possibly 5v.
As you can see in a couple of pics, the boards have the directions written on them, so that should help with X1 X2, Y1 Y2 on the IPAC. Just need to find ground, and maybe a 5v feed if it uses one.

So what signal does IPAC want from a trackball and spinner. They both use an optical sensor through a slit fly wheel, so there's a pulse, but there's also logic to say which direction the pulse should be sent.

I have an IPAC2 in my modded Arcade1up Street Fighter, along with some buttons for 2 players, 2x Sanwa JLF-TP-8YT Joysticks, an Ultimarc Spintrak, but no Ultimarc Trackball, only a cheap PS/2 mini trackball - so I don't use that feature on the IPAC2.
Here is a close-up of the IPAC2 board.

You will see the block where the trackball connector sits, it's for Ultimarc's own U-Trak Trackball. The connectors are labelled X1 X2 Y1 Y2 +5v and Ground. I'm just guessing, but I would expect X1 X2 is for left and right, while Y1 and Y1 are for Up and Down.
On the Golden Tee trackball motherboard there are 8 wires going to the main board, 4 are labelled UP DOWN LEFT RIGHT - so they could be wired to the IPAC X1 X2 Y1 Y2. I would need to use a multi-meter to see if a 5v cable is used, as well as ground. The trackball on the Golden Tee also uses a slit fly wheel, so it MIGHT work, or might not work. Since I have a un-used Boxed Golden Tee - the one in the pics above, and a loose, but well-used Golden Tee as a spare, I may as well give this a try. If it works, we all then have an "option" if anyone else wants to try - the unit makes for a really nice, and smart mini trackball as it's not that big. If it doesn't work, I will just solder the wires back to the Golden Tee board.

I'm just waiting delivery of an IPAC2 board - which, unfortunately, has been posted vie Royal Mail, and they're on strike for some days upto xmas.

So I bit the bullet and got a Couchcade from Santa to see if it scratches that arcade itch and I got to say it's been good fun. But the intention was always to see if I can hack into it and use it as a USB controller. Going to get a Pi Pico next and see if I can wire it all up, and get some code running.

Here's the inside, the spinner is on the left.

Nice. Looks like the connections are all labelled for you.
I'm still waiting for my order (IPAC 2) to arrive, but due to Royal Mail strikes it's marked as late as Jan 6th, so I can't do much at the moment.
The only issue I have of the Couchcade is the size of it, it's too big for the desk my Mister is using.

[LamerDeluxe]

I just got one of these:

It is pretty cheap and works well on the MiSTer (you need a PS/2 to USB adapter, not all types work with it). You can use another controller for the buttons or connect three arcade buttons to it (which you then have to somehow mount to something).

This one has a transparent ball with a green light, which turns red when one of its buttons is pressed.

[Chilli_Vibes]

I also have one of the above, it's ok for the cheap price they go for.
Problem is, you need a mounting plate for it, and I haven't found a UK seller that sells them, only a Chinese seller.

They have it at this Dutch shop, but I don't know if that helps much.

Thanks for the link. Unfortunately, because of our (UK) Brexit stupidity, buying anything from Europe is a hit-and-miss lottery at the moment.
But thanks anyway. I will post here if I get the Golden Tee working as a USB trackball, when the USB controller arrives in Jan 2023.

Sadly, yeah. And the other way around as well: A $1 PCB from the UK got stuck for a month in customs here and I had to pay something like $4 duty for it.

[Hetzen]

Yeah I was concerned about that, but it actually plays well from the lap.
The spinner and trackball have some spin momentum and feel responsive. The the buttons are crap, but they can be swapped out.

So I'll see what I can do with a Pico, without destroying it and see if I can get my head around the code. If not I can always recycle it on Ebay.

Which PS/2 to USB adapter did you use ? I have the Monoprice adapter and does not seem to work when plugged into the Mister. Ball lights green but I tried the input test utility, no response ! Thanks

The arcade 1up couchcade is reduced at game in the uk for £99.98 at the moment. I couldnt see if anyone managed to get one amended to work on mister or not though.

[Akuma]

I always loved Arkanoid, but I found playing with the mouse quite cumbersome compared to the arcade. Would anyone recommend playing with a trackball or is the spinner the only way to go ?

[Bristles]

Arkanoid, does infact play very well with a trackball.
I would go as far as to say, it plays slightly better due to how easier it is to manipulate the trackball with your fingers.
It's just a shame that the Tron games require an actual spinner, because I have never been able to get both Tron games to work with a mouse, trackball, or a spinner that is seen as a mouse.

That black splodge is to stop people probing the chip underneath. I've not found anyone who's been able to decode the signals.

You can go to Thundersticks and get USB replacement parts but you'll be adding a further $50 plus shipping. Also the ABC buttons are too far apart to be comfortable for missile command. That game needs volcano buttons

[Armakuni]

This looks like a decent open source option

Just picked up the Atari Couchcade with Trackball and Spinner for £70 (Game UK).
Clearly the HDMI box is useless, so apart from the buttons which are just push to make switches, does anyone know what I can do with the spinner and Trackball which are stock in these?
Maybe a USB encoder which i can wire into the unit and hook all the controls up to?

[ghorricks]

So I have a couple of Arduino's now and am wondering which project may work with this 6 pin spinner encoder as shown above

Did you get any of the controls hooked to to USB for MiSTer at all?

[ghorricks]

I've had no luck with all the common arduino project out there that say they work with a spinner or track ball.

Trackball is 4 pin (optical pickup)

• 5v
• GND
• something 1
• something 2

Doesn't seem to be USB, tried with something 1 and 2 on the data bus both ways around.

The Spinner is 6 pin (plastic wheel with holes in)

• 5v
• GND
• TX
• RX
• SE0
• SE1

Now I tried just connecting the first 4 (without SE0 and 1), but none of the common arduino code worked with it

https://github.com/Niels3RT/SpinJoy/tree/main
https://github.com/willoucom/Arduino_ArcadeSpinner

Why are these parts so undocumented?

I did not. I've got replacement parts to swap out to make it compatible, but it's sat in it's box for a while whilst we have work done on the house.

Someone would probably need to probe the logic chip to hack it. Which is beyond me.
