 1551 IRQ loader

Well, is is there one? I'm done with the first part for my next demo, and it uses all 64K by itself. The 2nd part will use the same display code and be at least 50K... So, I need an IRQ loader. Seeing how I don't even know how the 1551 communicates with the Plus/4 I'm not capable of writing one myself, at least not yet :/

 Questions

Hi MagerValp,

Sorry I can't help you with the 1551 IRQ loader question. I'm ashamed to tell you that I don't know much about the Plus/4's disk routines at all... Anyway, in a thread you started a while ago (the one with the 32 replies) I asked you a couple of questions, but you probably missed it. So: "Finally, three questions: are you also from Sweden? Can I insert your picture into your record (the one from your webpage)? What does MagerValp mean?"

Sorry, forgot to answer that. Yep, Sweden, the pic's online for everyone to see so feel free to grab it, and for my nick you'll have to grab a dictionary (try google happy)

OK, after checking the schematics I noticed that the 1551 has no way of generating an IRQ in the Plus/4. Turns out the kernal code doesn't seem to mind a small raster IRQ running while loading... Great, saved me a lot of trouble happy

And yep, my next demo will probably be 1551 only...
