It gives guidelines and code examples to follow when writing NEW scanners. To integrate your new scanner inside the above mentioned tools check the document about adding new scanners to FinalTAP (Stewart Wilson). text/html 2011-07-14T12:35:35+02:00 Luigi Di Fraia http://c64tapes.org/dokuwiki/doku.php?id=wiki:user:tce&rev=1310639735&do=diff Luigi was credited on c64tapes.org's forum as probably the single most important person for Commodore tape preservation since MTap and FinalTAP, due to his DC2N hardware and to his contribution to the TAPClean project. He has also been credited by FinalTAP author, Stewart Wilson, for single-handedly solving many of the intricacies of the brain boggling Super Pavloda and Cyberload tape loaders (amongst others). text/html 2011-05-11T16:40:36+02:00 Luigi Di Fraia http://c64tapes.org/dokuwiki/doku.php?id=links&rev=1305124836&do=diff TAPs * c64tapes.org - The C64 Tape Preservation Project database. * tapes.c64.no - The ULTIMATE C64 Tape Page.
