I tried to reply privately, but it bounced, so... To: WTW101@psuvm.psu.edu Subject: Re: Flakey AT bridgeboards Read of your Bridgeboard dilemma. I have had many problems with my XT Bridgeboard. It would boot sometimes, others not at all. Binddrivers wouldn't work, and then I'd get library not found errors. Intermittent problems are hardware related, and after reseating the chips and messing with the cabling, I resolved myself to resoldering all the connection points on the board. My Brdgeboard hasn't failed in almost a year, now. It went from 20% to 100% reliability. While this shouldn't happen, it's not all that uncommon. If you deal with electronics very much, you will see this in the future. Hope this helps. -- Dan Griffin griffin@frith.egr.msu.edu "Crritic!" -- Estragon

I think half the problem with these boards is the 24 inch flux-monster cable they use to connect the two devices. What they should do is shield these cables with a foil/pvc jacket.

If the problem is excessive cable capacitance, shielding will make it worse. -- Phil Nelson . uunet!pyramid!oliveb!tymix!hobbes!pnelson . Voice:408-922-7508 War on drug abuse- YES.
