In my several years of programming experience, I think I know how the Z flag
works on the Z-80.  I also think I know which way a JNZ instruction is supposed
to jump.  Anyhow, if no one else can find the bug, I guess I have to assy
that I have a garbled copy of DDT AND DCON.  How they both got to be garbled
in the same manner is beyond me...  It seems more likely that something in my
system is causing DDT to malfunction - something in the BIOS, or possibly a bad
memory chip.
