The maximum number of PC/104-Plus modules that can be placed on a stack is four. This is defined in section 3.2.2 of the PC/104-Plus Specification (version 1.2). However, the number of the boards on the stack may be less due to the number of PCI devices on the base CPU board. For example, a board based upon the Intel 430TX can directly support a maximum of 4 devices. If the base CPU board has the video and ethernet controllers included, then the maximum number of PC/104-Plus modules on a stack is two.
