What you need to do is just to emulate the Thunderclock in ROM. I don't have the ID bytes handy, but just get a hold of a copy of Beneath Apple ProDOS from Quality Software. It gives all the ID bytes needed for all peripherials ProDOS recognizes. BTW, this book is a MUST for any serious ProDOS programmer. ------- ******************** #include ************************** * Frank Uzzolino Penn State University * * f3u@psuvm 7 Hamilton Hall * * frank@psuvaxg (sometimes) University Park, PA 16802 * ********************************************************************** Flames (and soon my accounts) will be routed to /dev/null
