7.6.1Design and Theory of Operation

The bus board is designed as a passive link between the motherboard and the expansion modules. It is mounted with a screw.

The bus board has two ISA slots and two PCI slots, as well as a shared ISA /PCI slot. The power supply to the expansion cards is effected via the connection of the bus unit with the basic board. An external power supply (+5V and +12V) is provided.
