I have a book on writing code for Commodore printers and another one for disk drives like the 1541. As I delve into 6502 programming I'm more than a little curious how everything fits together.
I am a little late, but am kind of an IEC guy -- not your Jim Drew or Harold Seeley and Marty Franz, but maybe I can help. Things like this have occupied me for decades, and now, along with only hobby-ists and oldies (like me at a ripe 54)... I do have a very solid understanding of how it all works. Yeah, a little late -- I know.
Maybe you still want to do as originally intended, or maybe not. PM me. Who knows? Hey! I'm still busy trying to get the Warpspeed cartidge fast DOS routines into my ROM for the SuperCPU. A ten-year project in its entirety (my project), I found that Warpspeed was actually faster than JiffyDOS for many things, well, because they were the V-Max guys.
Anything I know is yours.
