14 PC/104-Plus – CPU-1461 Module
Figure 3 shows a module stack with the CPU-1461 on the top of two PC/104-Plus modules.
If standard PC/104 modules are used in the stack, they must be the lowest modules because they will
normally not include the PCI bus. An adapter module must be used.

Figure 3. The Module Stack
Do not force the module onto the stack! Wiggling the module or applying too much pressure
may damage it. If the module does not readily press into place, remove it, check for bent pins
or out-of-place keying pins, and try again.
