3.1 Item definition.
The memory circuit card assembly
provides the Mortar Ballistic Computer (MBC) with 14 336 8-bit
words of random access memory (RAM), 131 072 8-bit words of
erasable programmable read only memory (EPROM), and the RAM
standby control circuitry. The EPROM is organized into 4 lower
banks of 16 384 8-bit words each located functionally between
hexidecimal addressees 4000 and 7FFF, and 4 upper banks located
functionally between hexadecimal addressees 8000 and BFFF. Be for
programming or reading from EPROM, 1 upper bank and 1 lower bank
must be enabled. The memory organization and major hardware
functions are shown in Figure 1 and Figure 2. The connector
contacts are listed in Table 1.
