5i25_prob_rfx2.bit 5i25_prob_rfx2.xml A fresh card works. So now I am in search of a 10 foot length of 8 gauge equ flat ground strap, to tie the computer to the drive housing and on to the frame of the G0704 to see if I can absorb an ground loop spikes that may have blown the other card. But in Weston, WV, they are fresh out of hens teeth... So I expect its fleabay search time. For a 25' roll of 6 or 8 gauge. Amazon had it, 1/4" wide, bought 2 25' rolls.
