, the Card-PC contains 16 Mb of DRAM. The Card-PC
interfaces with peripherals through a single ISA-compatible bus that is used to connect to BD287
discussed below.
16.4 BD287 FRONT PANEL BOARD
The Card-PC MPU module connects directly to BD287 through its EASI bus connector. BD287
is proprietary to Zonge Engineering.
The BD287 board contains:
All I/O decoding
Flash disk for program storage, data caches and calibration caches
keypad decoder
annunciator
power monitoring circuits
power supplies for the digital circuits and LAN interface
The flash disk retains data for extended periods of time even when the GDP-32

is turned off.
The capacity of the flash disk is sufficient to hold many days of data under normal use. Time
series data obtained while running the AMT/MT program are stored on the hard drive.
