Heheheheh!!

Well at least you didn't fry anything!  Could have been worse.

I still haven't had a chance to check out all those caps.  Maybe tonight!

Wade:
Good news!

My parts arrived Saturday from Bob Roberts.  I didn't install the ARII rebuild kit since at this point, it didn't appear to be needed.

I soldered in a new RAM chip in place of the bad one (WOW, that was TOUGH... so tiny!), and the game works 100%!  I didn't know if the monitor even worked, but it's picture is quite good actually.  The blue is a bit fuzzy, but I figure a cap kit will solve that.  We'll see.  The tube has some burn, but it is where the mountains are (which never change), so it isn't noticable with the game on.

I'm happy!  Now to fix this thing up!

I'm keeping my fingers crossed that it keeps running for awhile.  Oh, I also threw the boards in the dishwasher because I was getting so dirty trying to work on them.  Came out looking great... I will probably throw the whole harness in there next, plus the monitor chassis and whatever else I can fit in there.

TTYL and thanks for the help!

Rocky:
Wade,

When you replaced the Ram chip did you solder it in directly or use a socket.

Wade:
No, I didn't use sockets, against everyone's suggestion.  I bought 10 chips and 8 sockets with the intention of replacing all with sockets.  Easier said than done!  It was impossible for me to solder the sockets on to the board.  There was simply no room to fit the tip of the iron!  I even bought the smallest tip i could find and filed it down even sharper.

I ended up soldering the chip directly because it was the only way I could get it to work.  If I have another chip fail, I will try soldering a socket again, since I might have a little better luck.

Hopefully, it will just keep working so I don't have to deal with it at all.  But I figure it will break again sooner or later.  Maybe I'll have more experience or have the right tools the next time. :(

TTYL,
Wade

RayB:
No room for the soldering iron tip?? You mean between the top of the circuit board and the plastic of the socket?

 *cough*  ...umm...

Did you consider soldering the BACK side of the board where the legs stick out?
