I've posted a new article with more info than I'm sure anyone would ever want to know about the Williams Special Chips: http://www.seanriddle.com/blitter.html I ran hundreds of blits on my actual games and under MAME and compared the results, and used a logic analyzer to study the signals...

I'm doing some in-depth technical analysis of the Williams special chip 1 DMA blitter chips, and I was wondering if anyone had any spare :) special chip 2s that I could purchase or trade SC1s for. I've always been interested in knowing if there were any more differences in the 2 chips beyond...

I swear I remember JP saying "ooh - TRex got him" after a game when the match failed, but mine does not. It shows the animation of the dino picking up the car, but then Richard Attenborough asks me to play again. Does anyone hear that message? ROM revision difference maybe? Thanks- Sean

I picked up a JP in pretty good shape, other than being very dirty. I've been working on getting the electronics working- resoldering a few broken wires, replacing a bad diode and a bad transistor, etc. I noticed the coil for the diverter wasn't installed and the associated flashers weren't...

Anyone have plastics for Bad Cats for sale? Partial or full set, new or good condition. Let me know. Thanks- Sean

Hello- looking for a Cinematronics Tail Gunner control panel shipped to 73007. Or a complete (working or non-working) game within a couple hundred miles of Oklahoma City (DFW, Wichita, Fort Smith, Amarillo, etc). Thanks- Sean

I got a HS a while back and the kickback coil was fried, so I replaced it. After that, it would usually send the ball partially up the right freeway, and it would roll back down in front of the upper flipper, setting up a nice ramp shot. But sometimes it would still be weak, so I looked at the...
