I'd update the bboah but I can't tell which is the "real" one anymore, there are too many online. Anybody know?
Also their page is wrong about the "developer" card, it's not overclocked, it just has a 33Mhz 68882 driven by a 32Mhz crystal. The CPU isn't driven by that crystal but the FPU optionally is.
It's not that rare of a card but yours is definalty different as it has both CPUs on it installed. I have two but only an 030 on them. You can insttall the 2nd CPU and the jumper is there. They were sold in the Amiga 4000/030 and also some A3000T's that did not have the 040 card on them (and no onboard 030 I have one of these)
