I would highly recommend just getting the ROMs.  Though is was the hardest Amiga to get ROMs for as I had to order special ROM tower ROMs.  Mine go where the ROM tower use to be.  But once you have em there is no more worries!!  I currently have a CSMK II 060 card, Cybervision 64 and OS 3.9.  It works awesome.  Worth the hassle to get the ROMs.  Contact Softhut, they were awesome.  I was able to return the ROMs until I got a working set for my 3000.  I guess it only would work with the ROM Tower ROMs.  The regular ROMs in the other sockets were a no go.
