SEGA System 16 trackball I/O

[Frank_fjs]

Does anyone here own the trackball I/O for System 16? Has anyone reproduced it?

I wouldn't mind having a go at reproducing it if anyone has one they can loan me. Would be fun to explore the trackball games and open up the 4 player games.

@Apocalypse have you done any work on this?

More useful tidbits of info here:

Someone else who repros them:

Sega 837-8586 (Trackball I/O module)
Sega 837-7968 (3 and 4 player module)
Sega 834-6180 (used by Dunk Shot)

Guru did some repros, I’ll see if I can find the schematic but he has a bunch of posts about it: http://members.iinet.net.au/~lantra9jp1_nbn/gurudumps/index.html

I also saw some here: https://forum.arcadeotaku.com/viewtopic.php?f=36&t=40851&sid=ed6a2fa9412e7fd8be00777acb9b7d3d

I have one of the guru repros. @Apocalypse was doing a multiplayer pcb repro but I forget where that ended up. Let’s see a combined pcb with both trackball and multiplayer, with a toggle or something

Other than SDI and Super League, what other System 16B games use a trackball?

Just posting to keep tabs on this.

I have one of the guru ones as well.

Excite League

Super League

Ace Attacker

Dunk Shot

S.D.I.

Action Fighter

Heavy Weight Champ

All use the IO board.

Same as you, was looking for an OG board to reproduce.
The other board (multiplayer) never got to finish it but pretty advanced.

 

[rewrite]

Would one of the repro's be useful to either of you?

I'm not using mine at present.

 

[Apocalypse]

@rewrite my goal was to have something also visually identical (same layout).

 

[djsheep]

If this goes anywhere, I'd be keen for one

 

[LazerFlux]

bump, keen on info due to my multis shipping soon

just as a heads up, this board will not work with System 16 A PCBs. The PCB part number is 834-5902, and you need two of them (one per player). I'll. upload scans of the SDI wiring schematic as well as pics of the PCB itself later.

The Scans for the schematics are here:

the pics of the 834-5902 board (top and bottom side) are attached to this post.

If this board could be reproduced, that would be awesome, because SDI needs TWO of these rare things. Better yet, it would be awesome if a single one could be created for both players.

I would go for 1-2 repros.

It seems that this link no longer works (or at least I can't view the page for some reason). Are these files available elsewhere?

Are these files available elsewhere?

The gerbers are still here.
I've also reattached the downloadable zip file from there.

Thank you so much! I have another question: do you know how the trackball plugs into the board? I haven't seen any photos showing the inside of a trackball panel or how exactly 3 of them are supposed to connect to the IO board. I'm going to have to make them myself so I really need to figure out what's required and how to connect it.

I'm not familiar with the technical details, sorry. But no doubt experts will help you.
