S4.2 is on the underside (Layer 2?) of the PCB. And S4.1 is only on the top (Usually called Layer 1).
So I would presume they used the number after the point to mark the PCB's phototools artwork, so they knew which phototool sheets needed to go where when the PCB was being made.
And maybe the '4' signifies the version of PCB for that product - Issue 4
- It's a bit confusing, being as they mostly dropped the Softy name after the Softy-2, replacing it with hand-held 'S3', and then an 'S4' (before the current S6, which isn't standalone anymore!)
