Re: "No board" error with the DRO kit

I just ran a new test with the "new dro software"from tom on my old 386-16
sx2 " I tested the board that I am sending to Fred Proctor. It ran fine on
both my 486-66 dx2 and my 386.
I susspect that if the softaware inn.t configured correctly that would do
it. Look at Toms web site for the addresses that match the jumper settings.
I use the second set from the left which is 544.
One other problem may be that you may have a folded pin or you installed the
74ls138 backwards.
