the syntax of the message doesn't mean much to me, but it looks like there's something wrong with your ROM. im assuming you own the hardware etc., so if youre having trouble with your ROM, i have functioning apple IIe, a quarda650, and performa ROMs and i'd be happy to send one to you. i'm afraid that's about as much help as i can be though.
I get that error message using the ROM I extracted from a Performa 630CD using the Fusion emulator's romdump program. Unfortunately, the computer in question is no longer functional, so I can't try to get another copy. Could someone send me a known-good ROM image?
