Re: booting macworks

all macworks versions I tried (from prerelease to XL 3.0) get the same result.
I'm now disassembling to understand were the emulator fails but the assembly code is not very compact. probably the code is compiled from an higher level language.

Lisa OS do not boot at all. The boot sector is read, then the disc is unclamped...

Does someone have good images of macworks discs, the one I found are bad for the tags CRC checksum.
