And for our Next Trick ... How 'bout a diyTrionic?

Fri May 8 17:38:12 GMT 1998

I sent this out to the list, but again, I don't think it made it
through.

Here are some other SAE technical Paper listings that I found doing a
search for SAAB and " ionization". They may be useful for the DIY
Trionic stuff.
