First - Download the zip file containing the backup that matches the software release for your control from here:

Acramatic 950 backup disks

YOU MUST REGISTER ON THE FORUM TO BE ABLE TO DOWNLOAD THESE.

The archive does contain a file for each disk called "UPDATE.CMD". A lot of virus scans and email systems will complain about this file. It's a completely harmless file and NOT a virus.

Extract the zip file. You will have 2 folders. 1 for the Master Save Disk, 1 for the Restore Disk.

Copy the files from the Save folder onto a floppy. Don't copy the directory to a floppy. Just the files. Your floppy should have only 2 files on it. UPDATE.CMD and MASTER. Master is a 0 byte file, so don't worry.

Copy the 3 files from the Restore folder onto a floppy. Your floppy should only have 3 files. UPDATE.CMD, MASTER, and RESTORE

This article covers the method of finding the control software version of your control.
