There is one Printed Wiring Board [PWB] size [dimension] defined in
PC/104. However the board may be produced in three different
configurations; the standard form is with either a PC XT bus or PC AT bus.
With the addition of the PCI bus, the specification is called PC/104
Plus. Up to six cards may be stacked together. The board or Circuit Card
Assembly [CCA] mechanical dimensions are shown above. An additional
standard; PCI-104 removes the IBM XT and AT
buses, and only uses the PCI bus [J3]. The board form factor remains the
same size. Boards may be stacked 6 high when using the PC-AT [PC/104]
bus, but only four of the boards may use the PCI bus.
