1581 Autostart Device # Changer by Jim Collette (January 1988) - This is a handy little utility that will let you create an autostart floppy disk that will change the device number to whatever you like when the device is turned on or reset, overriding the hardware dip switches.

d64 floppy.jpg 1581 Diag

This simple little program tests for two problems some first run 1581 drives might have.  As stated in a newsgroup post I found:

The first one involved an improperly grounded jumper (J1) on the PC board
inside the 1581 disk drive.  Allows the drive to use the 6 ms step rate.

The second involved a bad batch of WD1770 chips that were later replaced
with the WD1772 chip.  A typical symptom of this problem is a corrupted
directory after a disk copy.

d64 floppy.jpg 1581 Director v1.0

By Thomas R. Grady. This is a directory editor for 1581 disks. As noted in the built it documentation, this early version only allows for swapping positions of files and a few other basic functions. I like to include early program versions like this for historical completeness.

d64 floppy.jpg 1581 LM Backup

Based on LM Backup by Luke Mester, this version is for the 1581 drive. The interesting thing about this file copier is that it will let you copy files between partitions on the same drive with a 56k buffer. Note that line 2 of the program has the default drive set to 9, so you may need to edit it if you have a single 1581 setup as drive 8.
