Interesting N* software

One of the diskettes given to me has what looks to be support for running the Morrow DJ controller under N*DOS. Here's the equivalent of a README: 10!"LIST THIS PROGRAM" 20STOP 30 THIS SOFTWARE HAS A TIMING CONSTANT SET FOR 40 A Z80 N* HORIZON. 50 IF YOU HAVE A DIFFERENT SYSTEM THEN YOU 60 WILL NEED TO CALIBRATE THE TIMING CONSTANT. 70 PROCEED AS FOLLOWS\ 80 1.COPY THE DOSCHG DISKETTE 90 2.POWER DOWN AND HOOKUP 8 INCH DRIVES AND CONTROLLER 100 3.BOOTUP YOUR OLD N* DOS 110 4.PUT COPY OF DOSCHG IN DRIVE 1 120 5.PUT AN 8INCH DISKETTE IN DRIVE 4 130 6. LF BASIC 2D00 140 7. JP 6519 150 8. SF BASIC 2D00 160 9. NOW BOOT THE DOSCHG 170 THE ABOVE PROCEDURE TIMES THE 8 INCH INDEX HOLE 180 IN THE DISKETTE FOR 1 REVOLUTION OF THE DISK 190 AND PLACES THE COUNT INTO THE SOFTWARE. 200THE NEW TIME CONSTANT IS AT 64E5 64E6 210FOR REL 5 8DIGIT BASIC. 220 DOSCHG IS NOT DESIGNED TO RUN UNDER THE TIMESHARE PROGRAMS 230THE TIMESHARE PROGRAMS INCLUDE THE 8 INCH DRIVERS. 240 AT THE END OF BASIC. THESE ROUTINES ARE USED 250 YOU MAY REPLACE THE DOS 260 ON THE DISK WITH ONE OF YOUR OWN BUT REMEMBER 270 TO USE RELEASE 5 DOS ONLY. 280 THE FILE BASIC IS 58 BLOCKS LONG BUT 290 AFTER BOOTUP BASIC ENDS AT 65CAH AND IS 56.7 BLOCKS LONG 300 THE OLD VERSION OF THIS SOFTWARE USED 3 BLOCKS IN 310 MORROW'S CONTROLLER RAM. REV 4 OF HIS BOARD WILL 320 NOT ALWAYS WORK WITH A PROGRAM IN THE CONTROLLER RAM 330 THE SOLUTION WAS TO MOVE THAT SOFTWARE TO THE END OF BASIC 340 YOU CAN USE THE MONITOR TO TEST THE CONTROLLER RAM 350 BY TM E400-E7FF 0 360 THE PROGRAM GCOPY COPIES 8 INCH TO 8 INCH DISKS COMPLETELY 370 THE DISK MUST HAVE THE SAME DENSITY AND NUMBER OF SIDES. 380 THE DENSITY IS SET BY THE PROGRAM 8INT. 8INT IS USED 390 TO INITIALIZE 8 INCH DISKS. 400 THE PROGRAM COPY IS USED TO COPY BY FILE FROM/TO ANY DISK. 410 LOAD AND RUN BASIC AS A PREREQUISITE TO RUNNING 8INT,COPY OR, 420 GCOPY. YOU MUST THEN GO BASIC, BYE, GO 8INT,COPY OR,GCOPY AND THEN 430 GOBASIC. 440 PGM1 IS USED ANYTIME YOU MAKE CHANGES TO BASIC AND 450 WANT TO SAVE BASIC ON THE DISK. THERE IS A JMP AT 2D00 460 WHICH MUST BE REWRITTEN BEFORE SAVING DOSCHG BASIC. 470 THE BASIC IS SET FOR 32K STARTING AT 2000. Here's a directory listing: DOS 4 12 D 0 BASIC 10 58 D 1 2D00 CF 39 6 D 1 2D00 CD 42 4 D 1 2D00 8INT 44 4 D 1 2D00 GCOPY 46 2 D 1 2D00 COPY 47 6 D 1 2D00 PGM1 50 8 D 2 INFO 54 8 D 2 CONTROL 58 4 D 2 TEST 60 4 D 2 TEST1 62 4 D 2 Does this ring any bells?
