I’ve got an unmodified 512K logic board that boots up fine, but when I double-click (or use File > Open) on an internal or external 400k floppy, it gives me “the bomb” with System Error ID = 02.
Seems odd that it can read a disk to boot, but can’t view the disk content from the desktop.
It will even boot to an HD 20 external drive (using a 400k floppy with the HD20 Startup extension), but gives the same 02 System Error when I double-click the HD 20 icon.
It’s not the drive or the floppy cable; I’ve tried alternates with the same result.
Further oddity: I do not get the error if I use a 400k boot disk for an original 128k Mac!
System Error ID = 02 is an Address Error.
Anyone have any idea what on the board would cause this? Processor? IC chip? Capacitor? (C5 looks slightly distressed on one end.)
Thanks for reading!
