15 J1 and J2 for the ISA Bus The ISA BUS Connectors J1 and J2 carry the signals for the ISA Bus. These signals match definitions of the IEEE P996 standard. Below is shown a picture of the ISA BUS Figure 4. ISA BUS layout According to PC/104 specifications, KEYs are filled holes in the upper side and missing pins in the lower side of the bus connector. This is made to avoid the wrong insertion in/of another module. For further info about ISA (PC/104) bus, please refer to

8. Press evenly the module onto the PC/104 stack. The picture below shows a typical module stack with 2 PC/104 modules, 1 PC/104 16-BIT module, and 1 PC/104 8-BIT module. The maximum configuration for the PCI bus of PC/104 modules is 4 plus the Host Board. If standard PC/104 modules are used in the stack, they must be the top module(s) because they will normally not include the PCI bus. Stackthrough 8-bit module 0.435 in. (11 mm) 0.6 in.
