Re: Possibly the weirdest Tempest problem yet.

I had a Nemesis pcb that I bought from a fellow vacer.... It had a graphics problem with the spites iirc, he'd tried swapping all the custom IC's over from a working board and vice versa with no difference. Upon having a look and comparing it to a known worker, I noticed that one of the corner pins on the sprite custom IC had been very very neatly solderd/bridged to an ajacent pin (certainly wasnt a solder splash)... Unsolderd the bridge and it works perfectly again... Very strange that one !!

Cheers, Colin

  I just finished fixing a box of Tempest boards this week that I had sitting around for a long time. I came across one that had some miserable problems with the Mathbox. After careful inspection I noticed someone cut the +5v legs of most of the IC's on the board!! Someone actually went though the trouble of RUINING a tempest board. I'm happy to say I bridged all those cut legs with a clean solder bridge and repaired the main board and it's back in business.

  Has anyone else had to fix a deliberate sabotage? :)
