Drat. At least all hope isn't lost, I can still put that card in my Pentium 233, but since I got the datasheets for the 6306 and '07, perhaps if the pinouts are identical, I think I could probably try and swap the chips.. Even though I'm hesitant to do so as this card seems to be very obscure and I'd feel guilty about goofing up and irreversibly damaging it.I've been here before. The 6306 is a stinker and almost certain not to be recognised but the 6307 seems to work ok. YMMV as ever. Admittedly, this was when when I was putting hackintosh desktops together. Can't remember ever trying one in a real Mac.
I have not yet received the card yet, in the meantime I'm going to find a HD50 to DB25 cable so I can run my Jaz2 drive off the 7500.
@Tratkazir_the_1st yep that makes me think of gold plated cables for some reason
