+.Sh DESCRIPTION
+The General System Connect (GSC) bus
+is the core I/O bus for all HP 9000/700 workstations.
+All I/O subsystems connect to this bus.
+The devices can be either on separate chips, expansion
+cards or on an integrated megacell, like the LASI MBA.
+.Pp
+The
+.Tn GSC
+bus is a 32-bit wide, address and data multiplexed bus.
+In its "standard" implementation it has a maximum throughput of 160MB/s,
+the "2x" implementation reaches up to 250MB/s.
+Some HPPA CPUs directly attach to this bus, namely the PA7100LC and PA7300LC.
+.Pp
+As for the expansion cards, there are different form-factors, depending on
+bus-speed (standard or 2x) and specific models.
+The standard formfactor is the "EISA form-factor"; cards that look like
+typical EISA cards with a different connector (100-pin female EBBL).
+The Series 712 have their own special type
+of GSC expansion cards, called the "GIO form-factor", which is quite small and
+mostly has only one VLSI chip on it (in most cases LASI/WAX).
+Newer systems sometimes feature the "HSC formfactor", which is a 1U-VME
+card-like expansion card with a 100-pin male pin+socket connector.
+Mixing cards with different speeds is supported but downgrades
+the performance of the whole I/O-subsystem.
