- ; Hard-Trackdisk Example Routine - Loads sectors 880 to 883 off drive 0
- ; into $c0000 with an MFM buffer at $f0000
- ;
- ; No interrupts/exceptions are interfered with, and code is fully multi-
- ; taskable (within a Hardware or System based program)
- ;
- ; This is not an interupt-driven routine. nor will it ever be, i couldn't
- ; be fucked to do it... but wait n'see, i may have something sticky up
- ; my sleeve.
- ;
- ; Coded by psyKo, extreme hassle and lots of time have gone into this fucker
- ; so i hope you spread 4 all 2 c.. (retro corp production, 19/5/93)
-
- ; Note: This is the new-improved meatier/chunkier version..
- ; New control codes for the NuTrakker Segment are:
-
- ; d0 = 0 - Find available drives
- ; d0 = 1 - (new function) Reset drive (d1=drive) head to track zero
- ; d0 = 2 - Read Sectors
-
- ; The Zero Head function you should use before you load a set of sectors,
- ; NOTE: you dont have to do it every time you access the disk, just use
- ; it in initialization, and after a disk-change, or before a mass-multiple
- ; sector read (several Trakker Read Calls)... i hope it worx
-
- ; FINAL manufacture by Mr. Spillage 21-5-93
