Disk Surgeon an Ultrabyte Disk Utility
As you know Ultrabyte was a copy program, so this seems as it states a Utility Disk. Was it later included with Ultrabyte? Remember Ultrabyte was around for multiple years with multiple versions.
Also included three Public Domain programs.
1. a file copy
2. Single Track Copy
3. 4 Minute copy
This might sound strange today, BUT back in the 80’s many, many computer stores sold or rented computer disk with Public Domain software on it. Remember there was no Internet to trade software back then. We had 300 baud modems and small BBS’s.
