Konami M2 Troubleshooting

I recently picked up 2 “non-working” Konami M2 boards. I’ve since managed to get both of them working. This hardware is actually fairly robust and it took minimal effort to get mine working but a long the way I learned a lot about how the hardware works and some common problems you might run into.

A Better Vewlix Power Supply

My Work-In-Progress Vewlix F

Recently I’ve been fixing up a Taito Vewlix F cabinet, this cabinet has the optional “JAMMA Kit” which includes the incredibly crappy Wei-Ya P271 Power Supply. This Power supply is notorious for pulsing the 12V line and killing itself (and potentially PCBs) when run on 120V AC.

Light Output on Hyper Bishi Bashi Champ for Konami System 573

Last week I posted an article on getting light output from Salary Man Champ on Konami System 573, I suggest you read that first. Much to my chagrin the shift-register circuit I used there didn’t work with Hyper Bishi Bashi Champ. Through pictures I found online it seems that the 2 Player Hyper Bishi Bashi champ cart, while using the same light output pinout and having the same outward appearance and a very similar looking cartridge PCB actually used a very different light output circuit. Rather than a pair of shift-Registers it uses a pair of 74LS175 D-Type Flip Flops.

Here are some photos of the HBBC 2P cart (courtesy of nem on Arcade-Projects.com)

Light output for Salary Man Champ on Konami System 573

I’ve been playing around with a non-rhythm game version of the Konami System 573 hardware, namely I’m interested in the various “Champ” games, these are collections of manic versus mini-games where you smack buttons and hilarity ensues.  The most popular is Hyper Bishi Bashi Champ and Salary Man Champ. If you’re unfamiliar with the game each player has just 3 colored buttons (no joystick) and the buttons also light up corresponding to what’s happening in game.
