I use a PROM programmer manufactured by http://www.artbv.nl/.  I bought
it years ago because 1) it is a standalone unit that takes serial input 2)
the serial protocol is ASCII and well documented.  Although I've never
used it without the MS-DOS program that comes with it, I do know that I
could use it on a non-widows platform if I wanted to.  I have used this
unit to burn 3/80 PROMs, so I know it works.

(If you're interested in the full specs for the unit I bought,
