Good Day at the Test Box

["Thomas Droege" <tdroege2@earthlink.net>]

I have had a good day at the test box.  I now have 6 good memory boards and
working on a couple more.

I have not "solved" the flakey memory board problem but I have a solution. 
I find that if I adjust the RC time constant on the clock line so that the
clock pulse is between 160 and 360 ns the boards work.  They fail if the
clock pulse is outside this range.  I do not know why.  I don't understand
why this works, but it works on every board and the range is the same on
every board.  Merle, I know you don't want to think about this, but I am
curious.
