NeoGeo MVS 6 Slot Arcade Hardware Repair Part 2, small update

Slow Progress:

Slow progress, waiting, more waiting, ordering parts, ordering supplies and tools. meh! I HATE WAITING!

 Something along the lines of a Star Trek Replicator needs to be invented, would put an end to a lot of waiting. A lot of items i need have to be ordered online, some for them USA or China, for various reasons, mainly being where i live, no "Radioshack" or decent local electronics suppliers. Just one big chain, which do not always have what i need. "Maplin" and can be a bit pricey.

other things have also slowed progress, more important events in life haha pesky life getting in the way of my nerding around.

On to the actual progress:

Area around the leakage has been cleaned and acid neutralized, as per Part 1, i have lifted a number of ICs(chips) from around the Area, a few HD74LS05Ps, a HD74HC32P, the D4990AC calender clock chip, a NEC uPA2003C and the DM74AS244N closest to the battery.

I removed these for three reasons; 1. To make sure the traces that run under the ICs were not corroded / broken, 2. To Clean up any remaining acid / corrosion, and 3. To make sure the chips themselves were not damaged and replace if required.

There was a fair amount of corrosion on the legs of the chips and the solder wasn't great either. so i decided to just cut away the legs from the DM74AS244N and the 74LS05s, the other chips came out with little effort so i cleaned up the legs on them and will try and re use.

I've also replaced a electrolytic capacitor that was right beside the battery, just because i had a few spare from previous projects (Game Gear Recap i think)
 


So Where i am now: 

What i get when the its all hooked up:

it's actually white not pink, poor lighting and the flash from camera(my phone cam doesn't like to focus well or take pictures of CRT's).

From the information I've got so far it looks like something is stopping the 68000 CPU from firing up, either a broken trace somewhere or a ram issue. or both lol.

Waiting! for some New HD74LS05s and DM74AS244Ns. more solder and some flux as I've ran out / have little left.

I may also order up some SRAM chips but will wait until everything else is in place.

I may also have another Neo Geo board coming my way soon, another multi slot but with a less severe issue, although this is not concrete yet.

I am determined to bring this beast back to life.

So basically this update is a Load of babble 

Finally I would like to thank l_oliveira over on www.assemblergames.com Forum for some useful info and pointers (also great group there, recommended place to check out)
