Hallo Marko, > By the way, why do you need the "tya" in the code? The remains of some debugging I forgot to erase. Same for using address $0000 as temporary storage for Y. I had problems with receiving data and I tried all kinds of tricks. At the end it appeared that I addressed an empty drive :( > Or the sei and cli? IIRC this was used in the original C= routine as well. I also wondered as I thought that SEI would block timer interrupts. Then how could the computer find out about time-outs? > Maybe in the screen memory, to give some visual feedback > to the user, like in Fast Hack'em on the Commodore 64. Why didn't I think of this nice idea? The debugging mentioned above was in fact displaying info on the screen. -- ___ / __|__ / / |_/ Groetjes, Ruud \ \__|_\ \___| URL: Ruud.C64.org =====DISCLAIMER================================================================= De informatie in dit e-mailbericht is vertrouwelijk en uitsluitend bestemd voor de geadresseerde.
