To get the most out of the Commodore 64's limited amount of memory, the BBS program has been divided into several program overlays. All the overlay file names begin with "√bbs." and have a suffix in the form of an alphanumeric. For example:
- √bbs.ovl 8000 = Main Overlay, Version 8.0
- √bbs.ovl 8001 = Main Overlay, Version 8.0 revision 1
- √bbs.ovl 8100 = Main Overlay, Version 8.1
- √bbs.ovl 810a = Main Overlay, Version 8.1.0a
For the purposes of this manual, suffixes will not be referred to when discussing specific overlays, but note that version 8.1.0a does have some unchanged files from previous iterations of 8.0/8.1, so not all files will be shown with suffix “810a”.
