Hi, Fred:
You were right, Fred- changing computers solved the problem. I
switched from using my Pentium machine to my old 386-33, and it
worked fine. Some kind of timing issue?
One interesting thing, though. I still get this error, whenever I D/L
the pcode:
Board memory error: wanted 0c, got 3e at address 103f
But then it comes back with "Program D/L successfully."
At any rate, the board is up and running great. Thanks for all
your help.
Andy
