The CUBIC instrument electronics boards
were designed by Tim Entingh and Roland Green of our laboratory.
Roland Green and Mark Catalano did the printed circuit board layout
and populated the boards, which were manufactured by Trend Circuits.
This photo shows a segment of one of our digital boards, which
incorporated 11 different layers of wiring and power/ground planes
to achieve the reliable, low noise performance necessary for the
proper functioning of the instrument. The instrument is operated
in flight by an on-board computer consisting of a NEC V30 CPU
operating at 10 MHz with
2 Mbytes of memory protected from bit errors by an additional 1 Mbyte
of RAM that is used by our Error Code Correction hardware.
Although slow and small by today's PC standards, this computer is
adequate to the task and is robust in the harsh environment of space.
