GunCon2 on PC-monitor

oh so if I set my refreshrate right then any circuit will really work then right?..... that who thing that it caps to 15 sounds nice..... will think about it since the mame box I want to make will indeed be using a arcade monitor;P....

anyone know if you pay shipping on the ic? I'm maybe gonna order one:P

ARTIFACT:
What's the latest on this?

I am putting together a cabinet, and if there is a way to use a lightgun, I'd like to know! :)

Thanks in advance... I found this thread because it's linked from the Wiki:

Back from the dead!  What did happen with this?  I have a Betson, an AVG and 2 Sony brand Guncon2s, am I out of luck?

Yes.... It never worked properly.... Andy tested it, I tested it, and a few others as well. Nobody Ever got it to work in a useable way.

Your choice is either Act Labs Guns or LCD Topgun.

ZeroPoint:
The original "GunCon2 on PC-monitor" circuit really works very well. I have not tested Andy's circuit, but I can tell you how mine works. There are no microcontrollers, just standard logic circuits used. One XOR, one FLIP-FLOP and one AND gate.

It is really simple:
First a standard XOR sync combinder circuit. After the first XOR gate for the horizontal sync I just divide the signal through a D-type positiv edge triggered FLIP-FLOP. To get the original sync width back I "AND" this result with the original signal from the XOR gate and feed this resulting signal back to complete the XOR circuit. The last stage in the quad XOR inverts the signal into a negativ composite sync that needs to be divided with resistors (not the best way) to give the proper voltage to feed the gun.

I tested this circuit up to 1024x768 60Hz on both the original Blue Namco Gun and the Scorpion gun. Both working very well.

Pros:
More original feel than the LCD topgun
Gun can be used much closer than the LCD topgun

Cons:
Needs flashing of the screen to work properly.
Calibration is resolution dependent
Only for 31Khz+ CRTs (Possible to make it autosensing for dividing or not for use from15Khz and upwards)
Works best or only with lightgun games where the LCD TopGun can be used for nearly every game that can be controlled with a mouse

My recommendation is to use the LCD TopGun with SMOG's driver. I recommend to take the leds out (or use one high bright instead of three) and mount them as close as possible to the screen. You can also bring them closer together vertically than original.

Anyway...if someone wants the schematics, tell me so.
