And put in a DOS loader as you suggest. Or *maybe* TEENY would fit. Probably not, but maybe. Of course you will break some applications and optroms that have any dependency on bytes in the cassette code. And I do mean bytes... some things just depend on short subroutines or just raw data content of the ROM for various tricks. In CloudT I hook all the cassette stuff to create a simple file/load save system to a browser file queue because there is a bunch of code there that knows how to deal with the Model T file system and formats. It was a hack but it works. -- John.
