27. MOUNTING PROMETHEUS ON A BASEBOARD
Prometheus is designed to allow installation upside down onto a custom baseboard. The CPU
board may be thought of as a “macro-component” when used in this way. All the key I/O headers
on the board face up and are at an even height, allowing the board to be turned over and
mounted onto a base board. A mechanical drawing showing locations of mating connectors on
the baseboard is shown on the following page.

The board-to-board mounting height for this application is 14mm (.551”). Spacers for this
application can be purchased from many suppliers of metric hardware. Standard spacers with
metric length will have metric threads (for example M3 x 0.5). Diamond Systems can supply a
custom-designed 14mm aluminum hex male/female spacer with #4-40 threads (DSC part no.
684045).

Using the board in this manner eliminates all connecting cables for most applications. All
connections except IDE, floppy drive, and switched power output are accessible through the
vertical I/O headers on the board. If you need to use IDE, floppy, or switched power output, you
will need to use cables to access the corresponding I/O headers.

Note: The -12- in the Samtec part numbers above indicates standard insertion force components.
This may be replaced by -37- for low insertion force components. Because of the number and
location of the mating headers, the effort to remove the Prometheus from a mating board is
significant and requires careful effort. Therefore low-insertion force components may be preferred.
