The CPU card is found plugged into the PC/104 bus connectors of the I/O card.
The CPU card operates with a microprocessor running at 133 MHz. The CPU card has a built-in
flash hard disk drive, which contains the operating software, parameters and calibration points
for the system. The processing power of the MPR E-Scan is performed by the microprocessor
on the CPU core module. The layout for this card, with standard cable connections, is shown on
the above figure for the CPU card layout. When the Comm/LPT card connection board is
supplied, cables also run between the parallel printer port and the connector board. The optional

Block Mounting Kit addendum.
This card is always installed on the I/O board and additional cards such as the 422 optional card
