Exidy Pepper II Repaired - Need a comparison to known working hardware
Hello all,
I recently acquired Pepper II in non-working shape, and after a some cleaning the connections on the PCB, the game came up, but still had a few graphic glitches and an intermittent audio communication error. When looking, I found that some genius decided it would improve things if they soldered the boards together at the interconnects, thus making it impossible to separate the boards. Needless to say, I had to cut off the board interconnects and replace them with .156 right angle connectors. Also, while I was at it, I replaced all electrolytic caps on the PCB and cleaned and reseated all the socketed chips. The game seems to be 100% now.
Here's the thing, there's a couple differences between MAME and the original hardware. I need to figure out if there is something else that is a problem, or if it's just one of those little differences in emulation versus the real thing.
First, when you first power on the game, Pepper appears in white at the bottom center of the screen, but on the original hardware, he always appears in white in a random screen location. When he turns yellow, he appears back at the lower center of the screen.
Second, some of the sound effects are distinctly different than in MAME. Specifically, the sound when Pepper eats the roaming eyes it much higher pitched - it almost sounds like the same sound effects in Atari 2600 pac man.
Can someone else with a Pepper II advise if they have the same differences on their hardware?
Thanks!
Sean
