You can always send me the dead modules and I'll rebuild them (GlitchWorks
== me, my wife sometimes helps with assembly). Whatever you do, don't throw
out the dead NVRAMs -- I'll buy them or pay for you to ship them or
whatever, they're not making more and they're the only solution that's 100%
Yeah, the "still works but pukes errors" is the typical symptom of the
newer, slightly incompatible 48T02s in Sun machines. I don't recall if mine
kept accurate time with the newer modules.
