C_Bus
From ArchaicPixels: HuC and PCEAS Documentation
This article is grossly incomplete, and is a Work-in-Progress.
The C Bus is the bus interface used in NEC's line of PC98xx personal computers. It is roughly equivalent to 16-bit ISA, though the pinouts and edge connector formats are different.
The number of existing PC-FXGA and FX-98IF add-on cards using this bus interface is high, while it is rare to find one for ISA.
