  Unfortunately, I never got the chance to really investigate the
problem.  I was going to have one of the technicians at work try and
find out exactly what was wrong in case it was an easy-to-fix problem,
but I was more interested in just getting a working memory expansion.  I
DO know that the actual RAM chips weren't at fault. 

  As far as I can guess, there may have just been a batch of boards that
slipped past quality control at Supra and I just happened to run across
several of them.  I really dont have any other qualms with Supra, but this
experience made me hesitant to recommend this particular product.

  All in all, I dont think there is anything to worry about.  It was very
obvious that something was wrong with the board (i.e. programs crashing,
disks being trashed, guru's attacking from all sides, etc.).  You would
know if you had the same problem I had.

  Just wanted to clear it up...   Dean
