WARNING!
Before the PC-500 is powered on for bench testing, all eight
standoffs, screws and washers should be secured to the
board. The standoff pieces will ensure full support of the
PC-500 not only on all four sides, but also in the middle of
the board. These hardware pieces will reduce the circuit
board flex when the PC/104 expansion board and/or the SSD0
are inserted. Flexing of the PC-500 board should be avoided,
since it can cause problems with the copper circuit traces
Figure 2-4 PC-500, keyboard, and monitor and the surface
mounted components.

Accidently crossing the wires, i.e., pl5V wires into
the ground connector or the ground wires into the +5V con-
nector will damage the PC-500.
