Twisted where are you at? I have seen some busted gun games go dirt cheap at the winston auction before. I considered a jurassic park sit down. It went for 25 and actually worked mostly.  Just so big to grab for just parts.

I'm located in NH... arcade selection around here is very slim. nearly all of my machines were shipped from some place else.

the nearest auction is a 5 hour drive away in CT. I've never attended but there's a lot of really bad reviews about them not paying consignors, and having shill bidders driving up the price of the lots. Rumor is they're going to be shut down soon due to lawsuits.

since this is it's own thread now... I built all the harnesses needed and got all the gun board working with an original NAOMI unit

As for adapting this to a PC for use with MAME and other emulators, I've confirmed that the gun sense board output does indeed go between 0V and 5V. On the Y-axis 0V is at the bottom and 5V at the top, but for X axis 0V is on the right and 5V is on the left. I'm wondering if this is because they originally designed the board for use in a mirror cab where left and right reversed. In any case once I have an analog I/O for the PC to test with we'll see if the X-Axis can be inverted .

I still haven't got around to ordering an A-PAC or uHID but I want to get this setup up and running on my projector before I work on adapting it to a PC.

Yeah both x an y are inverted.... typically the top of the screen is 0. 

If it's sending a variable analog output then there shouldn't be any issues adapting it to the pc.  What about off-screen shooting (reload)?  I'm guessing the triggers just use the standard jamma harness correct?  How about force-feedback (if any)?

How much was the unit?  I'm just trying to decide if this is more economical than the wiimote solution.

Assuming they don't cost too much, the interface solution I would use personally would be a cheap 6 dollar Arduino clone.  There aren't a lot of I/O pins, just the triggers and x, y and an Arduino would allow for easy switching between dual joysticks and dual mice, allowing for maximum compatibility.  It could even handle some force-feedback or blinky lights....... basically an entire light gun cab could run on the one board.

top right is 00,00
bottom left is FF,FF

this system is too new for JAMMA, it's JVS based which is why it works this way since JVS uses separate boards for each function instead of integrating everything onto the game PCB.

the Gun board sends an "off-screen" signal that is tied to button 1 so if it loses track of the gun it sends position 00,00 and "pushes" button 1 for that player. The trigger is button 2. There's no provisions on Gun board for kick back but that's because it doesn't need to, those provisions are handled by the normal JVS I/O board, or in the case of a setup on a PC could be handled by something like a PAC drive.  The Gun board pretty much only serves to track the gun position, I'm honestly surprised they even bothered with passing the trigger button signal through it.

My guns don't have kick back but the mold has a slot for the solenoids, I'm honestly not sure which games offered it. House of the Dead 4 and other newer Sega games also featured an accelerometer and an additional button for an alternate fire mode. Again, none of these were routed through the Gun board, they went straight to the JVS I/O since the Gun board just does pointer tracking.

This is NOT an economical solution, There are 10 IR emittor boards that go for $25-$35 a piece, the sensors in the guns tend to go for $90-$150 a piece and the Gun Sense board tends to go for $100-$150 if you can find a working one, and I don't think I've ever seen the Gun-protection board for sale. [There's a design flaw with the gun sensors where they tend to kill the gun sense board, the protect board fixes this, but it's also why the price of the parts is so high  (lots of boards getting killed by this over the years), would be pretty simple to build your own though, it's all just passive components.] Then you have all the harnesses and of course the gun shells and hoses. I bought all of my parts together in a lot for $250 and I've easily spent another $60 or so just on connectors and wire to build the harnesses to put it all together.

My goal was never a cheap solution, I wanted a solution that used actual arcade guns.

The cheapest method would be to pick up a Sega Jurassic Park game on the cheap. I've heard lots of stories of people picking them up for as low as $75-$150 range, which is a steal considering the e-bay prices for the gun electronics.

So far it seems like my options are the U-HID, A-PAC and the Arduino based KADE setup. U-HID looks nice but not worth the $80 price tag, Feature wise the A-PAC isn't bad but I really really hate the screw terminals that Ultimarc insist on putting on everything they make... I'd rather have connectors for everything. The Kade setup is definitely the cheapest but it only supports up to 4 axis at the moment. That will get me by for now since that's technically all I'll need to get up and running with these guns, but if I do decide to add in accelerometers for support in certain games then I'll have to find another option.
