Default Re: My 500+ Project

So I took another crack at reviving my 500+ board last night:

I replaced the faulty trace with a direct wire connection:

I also tinned the feet of the Gary chip and tested a bunch of traces around the battery area with my multi-meter to ensure they weren't broken (none were) and then fired up my 500+.....

and got this: http://dl.dropbox.com/u/71121999/Ami...%2052%20PM.mov



It doesnt even attempt to boot from a floppy either so Im calling this mobo BUSTED! Oh well, it's been fun trying to repair it as I havent done any board level repair work sine about 1998!! gave me a good excuse to buy a new soldering iron too.

Anyway, all is not lost, I ordered a tested and working Rev6a Mobo from germany and will swap all the ECS chips onto it and upgrade the on board ram to 1MB using the chips from my Rev8a so it''l pretty much be a 500+ regradless.
