Also we will be able to handle 1571 .d71 and 1581 .d81 files. All of them are (AFAIK!) simply linear disk dumps. I myself can produce disk dumps from 8050 disks (~500k) and 8250 disks (~1M) per disk with my setup. They have up to 29 sectors and up to 77*2 tracks. They also handle up to 224 directory entries. What actually are you planning to do? I mean, either provide standard CBM formats, or simply use the filesystem directly. I think 1M per disk image seems fine already, and for larger files, simply use the host systems directory structure. BTW, VICE handles directories in the host directory tree as "DIR" files (in the directory) and you can 'open 1,8,15,"cd:foo/bar"' into them :-) Andre -- Email address may be invalid.
