Probably it is not a difficult project- but, I don't think one can make one
that easily- NI has probably patented all of its hardware. But, then, I
don't know how prologix is able to make it.

All the basic patents on GPIB have run out long ago, they belonged to
HP anyway. Even the NI patents (relating to IEEE-488.2) are getting
long in tooth. (about 15 years old) The converter is not particularly
hard, but you will have to learn IEEE-488 etc. well to make it.
