I assume that's HPGL of some flavour

Do a search for hp2xx. I found this about 6 years ago somewhere on the
net, it would translate HPGL into a number of formats, including .eps . I
assume it's still around somewhere, probably updated by now.

It would only handle a small-ish subset of HPGL, but it managed to
translate the output of EASY-PC (a cheap PCB layout program) into .eps so
I could include it in my LaTeX documents.
