burny-2.5

Hello all, I have a Navigator 60ST model plasma jet cutter here without a
controller. It's got the L150-S optical scanner (i think that is the
model). I'm have a terrible time finding information on this beast. The
manufacturer recommends the burny 2.5 controller, but after reviewing it,
I'm finding it pretty weak. I was wondering if anyone here has experience
with using a PC to replace the burny 2.5, and can point me to wiring/pinouts
anywhere? ----thanks, Dave L.
