Skip -
I would suggest building an adapter rather than buying a prom burner.
The cost of proms (when you can find them) has gone out the roof.
E-mail me direct if you are using 82s129s or 82s131 Proms as I have an
adapter already built to handle these proms (they were used in the Motorola
Syntor and MCX-100 radios)
See: http://www.brinkleyelectronics.com/adp/adp_fr.htm
You can also build the adapters by hand, all it requires is a header and a
socket and some time matching the input and output pins.
The cost of the eprom adapter is about what you would pay for a couple of
proms.
