Apollo 2030 cards are the worst accelerator cards I ever seen for the Amiga :-(
It are slow (even doesn't compare to the slowest GVP card) and there is no real scsi chip on it, only one big MAC230 (if I remember well) that recreate it (badly) among other things...
For getting mine working I was forced to install an internal scsi hard drive WITH active termination AND an external active termination, as shown :
HD + active terminator --- A2030 scsi --- external scsi plug + active terminator
I was forced to use two identical edo simms, and mine was limited to 32MB total :-(
Try this, if it's still not working try changing the kicktart rom back to 2.0 (though my A2000 was 3.0)
tell us what's next :-)
