Hello all,
If anyone has the CQ Magazine this far back, there was a product review. Maybe
the programmer is mentioned there.

Subject: Re: [CQ-Contest] Doctor DX clone (if you never used it, you just don't
"get it")
In a previous discussion of Dr DX a number of years ago (maybe on this
list, maybe elsewhere...), I recall the programmer of Dr DX responded to a
post about it. IIRC, he was a 6-land guy. Maybe some google and/or list
archive searches will find that post, if someone is interested in pursuing
it.
