My experience has been that +5 failing doesn't kill much (if anything) off. Now losing the -5v is the kiss of death for your 4116s.. :) If you're not a "purist" (going for the complete restoration -- Hi Chris!) I'd definitly recommend taking this opportunity to change out the crappy wms supply and going to a switcher. If you did have some of the ram wiped out you might consider the 4164 hack (which also doesn't need the negative voltage). Kurt On Wed, Apr 27, 2005 at 02:03:38PM -0600, Sean McLachlan wrote:
The +5 on my Joust power board went out, the heatsink mounted transistor is fried and from the looks of the burnt connector some serious current went through it. I'm going to have to replace the molex or jump the wire someway, I've got huge resistance on it when it's connected now.
The header pins have cold solder joints aplenty, I'm hoping it was just a bad connection that caused the current to jump.
Have I fried anything on the boardset when my +5 went nuts? I'm hoping no, and I guess I'll really know when the PS is back up, but I'm wondering what to expect.
