Null Driver is a ProDOS device driver that does not store any data sent to it. It is for use when you have a program that has output you don't wish to store. The volume is named /NULL and is installed as slot 1,drive 1. You may send it as many CREATE commands as you like. On it is one file, NULL which you may READ or WRITE normally. Test your new compression program by writing all data to /NULL/NULL. There are two files: NULL.DRIVER and NULL.INSTALL BLOAD NULL.DRIVER, then BRUN NULL.INSTALL Null Driver does not conflict with VBLClock, though together they use up all of page 3. Null Driver is ReplyWare: If you use it more than twice, send me a message telling me you use it. This will improve my mental outlook, if nothing else. No charge for noncommercial use.
