I have one of those though mine's a 250mhz. I'm not using this card because i have a number of faster ones from Sonnet & Powerlogic.

In my box of G3 cards I have a couple of Newer Tech floppies. Ones titled MAXpower then a number I can't read

the others titled NUpowr G3 version 1.0.3. I don't seem to have the manual. PM me if you need a copy of those disks

I have two links on hand that may be of use to you
