Hi all, Does anyone happen to have any IBM 2315 disk packs[1] available? The National Museum of Computing in the UK are at the point where they're looking for a few as part of the restoration of their 1130 system. [1] or functional equivalents to the genuine IBM ones, if any exist; by the sounds of it packs from various sources may physically fit, but sectoring / disk surface / other details vary. thanks, Jules
