SC501 is a 7-slot backplane designed for Z50Bus.

SC501 has 7 Z50Bus sockets, with narrow (0.6″) spacing.
Backplanes with narrow slot spacing (eg. 0.6″) are best suited to building compact systems, while wide slot spacing (eg. 0.8″) is more convenient when experimenting and developing hardware.
The main features of this design are:
- Seven Z50Bus sockets
- Simple passive design
- Compact 0.6″ (15.24mm) slot spacing
