If it may help at all, hop on Ebay and get a Rom 3 GS...
I have tried my 2 CFFA cards now in a total of 9 Rom 01 GS's of every different motherboard revision, and it so far only works correctly in TWO of them and those are the kind that have the SOLDERED VGC chip AND NO internal keyboard connector in place....
Even with that mother board, it ONLY worked with the Transwarp 1.8s in place and the CFFA in Slot 2.. I have NO idea why but that is what I have come up with so far.
HOWEVER, in a Rom 03 motherboard, I have tried 5 of them and so far if you have either NO labels on your roms, or if the Labels are NOT neatly typset ones, then it has worked PERFECTLY in every slot of the 2 I have that have the earlier printedhand labeled rom 03 labels on them...
Not sure about anyone else, but that is what is working for me so far, and it applied to BOTH my CFFA cards so it just isn't a fluke it would seem.
Good luck! When it works, it works great!
The one machine I decided to put it in permanently is a:
Pacemark Ram card 4 meg - 70ns simms
Slot 2 - CFFA Card
Slot 3 - Transwarp GS 1.8s 32k at 13.75 mhz - at 15mhz Appletalk quits working..
Slot 4 - Future Sound GS Stereo Output/Digitizer Card
Slot 7 - Ramfast Rev D Scsi Card 256K
Once I found a solid machine all was well for the CFFA.
