Repair Party @ Channelmanic's

It was having another issue too. It wouldn't coin up. Worked great with no audio in free play mode but no coin up. There's a small Seibu custom chip that the coin up signal goes into and it made it to there but nowhere else. I reflowed it but no change.

Well, I looked it up in MAWS to see what audio chip it used and it's the same Yamaha chip that's on the silly CPS1 A board. I thought "maybe it won't coin up if it can't make the sounds."

Removed it from the A board and installed it... It works perfect. Sound system booted and worked... and coin ups are working.

Sooooo.... 5 reflowed surface mount ICs, replaced 1 missing Yamaha YM2151 sound chip, and patched three gouged traces.

We'll see how it goes.

Oh, and I forgot... "Replaced 1 missing EPROM" too.

DAMN! CM sounds like you built the game.

Well,

That's what happens when you flex game boards that have surface mount chips on 'em!

Too many ops just manhandle these surface mount boards without understanding what it does to them. IT POPS THE LEGS OFF THE SOLDER PADS!!!

Oh, hey guys... figured out what was the problem with my laptop and the EPROM programmers...

Andromeda Research has a small freeware program bundled with their software which is a parallel port driver that allows for better access to the parallel port when in XP/2k. Installing that program fixed the programming errors I was getting with both the ChipMax and TopMax.

Glad you figured that out... Since it was working until I touched it, I was a little concerned.

Awesome! Was figuring there was a driver issue that windows may have corrupted during some of those reads.
