There are no other tables on disk. The disk itself is hard-sectored, with a sector length of 150 bytes and 16 sectors per track. They're interleaved 3:1 and grouped into blocks of 1200 bytes. The directory would correspond to block 0 and there are 72 entries in it, less the header. I can get the raw text, but how it's linked together and what file names might is still a mystery. --Chuck
