drivecoding

Hi people!

I have looked for info on the topic with google, but I think there is very little info on this out there. Anyone can post some useful links?

other questions:

- anyone can give me a sourcecode which would upload any kind of prg to the drive, and execute it ?
- why atn cant be used to send bits ?
- where is the entry point in the drive rom of the soft reset routine?

count zero: not with the approach i use. it scans a track for the needed sectors on the drive side, then fetches and transfers only those sectors.
it's ages ago since i had a look at that ar loader and my copy of it, still i think this technique can be applied to it. and it's not noticeably slower, since you need only one revolution to scan the sector links. and it's faster for the first and last track of a file, and faster for files with only a few blocks. the drive ram, however, might not be large enough for an updated ar loader, i still have to evaluate that.
