     It refers to compatibility with older GS software.

     Here's some info on GS System versions which helps show which ROM models
are most likely to be compatible with software released under a particular
System:


System       GS/OS         Date        Tool Patches     Finder
6.0.1        v4.02       06-May-93     ROM-01, ROM 3      6.x
6.0.0        v4.01       04-Mar-92     ROM-01, ROM 3      6.0
5.0.4        v3.03       20-Aug-90     ROM-01, ROM 3      1.3
5.0.0        v3.00       14-Jun-89     ROM-01, ROM 3      1.3
4.0.0        v2.00       18-Aug-88     ROM-00, ROM-01     1.2

System    P16 & Loader     Date
3.2          v1.6        14-Jun-88     ROM-00, ROM-01     1.1
3.1          v1.3        29-Jun-87                        1.0
3.0          v1.3        29-Jun-87                        1.0
2.0          v1.2        18-May-87                       Desktop
1.1          v1.1         2-Dec-86                       Desktop


     Running a particular piece of software doesn't necessarily involve parts
of System which are changed (or changed enough to have much impact).  So,
newer GS's can run lots of the old stuff.
