512 byte seectors. one map sector, one byte for each potential sector, I had a few mdvs of 250 sectors. Note tpp, every file fragmented of necessity by the interleave factor allowing the QL to digest the data from one sector before reading the next, some 11 or 13 further on. If the file were contiguous it would require a full revolution between sector reads. I had some of the Psion package which were "Turbo Load", laid out for optimum pickup speed, they had to be copied by special procedure equivalent to a DOS DISCOPY. -- No virus found in this outgoing message.
