I'm looking for P&B style double and triple pole, double throw relays, that
fit into a base.  I don't know the number, or the generic style to search
on.  Maybe you all have an idea.

A buddy of mine asked if I'd shop a new Dell system for him.  I was
surprised to see Dell still shipping CRTs with nearly all of their low-end

My 1997 vintage KV32S22 died completely during the final moments of the AFC
playoff game last month.  After reading this group and a bunch of googles, I

I have an electrical problem with my rental unit.  The house is about

    I bought a new Compaq Armada 1520DM laptop around 1997.   A few years

"playing" (audio)  the CD.  Note: I have not used the CD ...
