Tempest with Optipac problems...

Pages: (1/3) > >>

Added a CPU to a dead Tempest today.
Wired up the optipac to the original spinner...

nothing.

FYI, I did enable 'mouse input' in MAME...anyone have any idea what I might have missed?

Any assistance appreciated.

I think you'd be a lot better off to pot some pics of your wiring and explain a little more of what you did and all that good stuff.

It sucks that I cant post pics at the moment-
Wired the Optipac up correctly as far as I can tell, even tested the board and verified 4.6v and ground, the 2 outside signal wires I put in the y1 & y2 ports, but can get no response.  I also flipped the signal wires and still nothing.  It's pretty clear which wires are G and 5v, and I've got that right, so I'm baffled as to what else it could be.

From what I've read, you pretty much wire it up and enable mouse input, though I can't seem to get anything out of it.  Is there something more specific that could be the issue?

Okay, figured out a way.  (new phone) ;)

Here's the spinner, and the optipac.  (Ground wire black on spinner, but green to Optipac, jumped from harness.)  Anyone see anything wrong?

Does the spinner work outside of mame? Like does the curser move side to side? If it does, than it could be as simple as going into the mame ini file, and changing a 0, to a 1, in one of the settings!
