; 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
