[DSP-10] Need Help!

[Chuck E. Swedblom]

Hi Bob,

I forgot to mention that I am using the KK7P boards and followed your
instructions
in the down load readme files to use the correct programs, as follows:

Read3x.txt         3/15/04
Uhf3x.exe          3/10/04
Uhfa.cfg             3/11/04
Uhfa                   3/9/04
Egavga.bgi          2/15/94
Gnu_gpl              9/3/99
Ezfast                  1/4/80

These are the only files in the DSP10 folder that are loaded with a .BAT
file
as suggested in one of your write ups.

I always see that the RED LED flashing before attempting to load the
programs.
I now see why the RED LED is glowing after loading the DSP.  I do see the
interrupts.

What really bothers me now, is why dosn't my old programs load.  They are
in a different folder that has not been disturbed.  

I have a schedule to run an EME shot this weekend using DSP10's on each
end.  I sure wish I had waited until after the schedule to load the new
stuff. Hi.

73, Chuck
