2 bit irq loader
Hmm, just a question...
Is there a 2 bit irq loader, which doesn't require blocking other interrupts while loading a byte?
i.o.w. Is there a realy fast irq loader which doesn't block any interrupts and let me use my beloved sprites? :-)

Why don't you just check it yourself? Doesn't take long to code, really. :) |

Oh, and btw., i have an idea on how to make the 2bit+atn protocol work with multiple drives connected (and turned on). Will implement that some day.. |

Sending "m-e" 0502 784c0602 to all other drives?
("m-e" 0402 is even shorter :) |

Dunno, I'm trying to code something for a drive for the first time. So I don't have any experience with this.
also, Vice lacks a way to "debug" the drive. I'd like a drive monitor as well :) |

Obviously you haven't tried that code or muting other drives when using 2bit+atn protocols before posting this :) |

Just out of interest, does this involve programming the idle drives to execute some kind of loop or is it something more convenient?

It's a loop, but i will try making the loader work on all connected drives, i.e., installing it on any drive on the bus and let the user load from any drive, i.e., the loader tries finding the files on any inserted disk. |

krill, I think this is an overkill, also what happens if the c64 resets while the demo is running ? he will find himself with most of his drives in an infinite loop. |
