Design 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.
