2.5.1 Memory Card interface
The memory interface consists of a PD6722 controller and two PCMCIA compatible card
sockets. Both sockets consist of 60 signal and 8 power connections. The controller
communicates with the CPU. Card insertions and removal are also detected by the controller.
The MemCards are PCMCIA-ATA compatible. The MemCard files are MS-DOS compatible, and
they can be copied for archiving with any MS-DOS compatible computer equipped with
PCMCIA-ATA specification compatible card drive.
The MemCard function is optional. The operation requires a software option.
The monitor software can be downloaded to the monitor Flash memory through the memory
interface.
2.5.2 Power supply
The memory section receives its power (+5V, +12V) from the CPB. PCMCIA card programming
voltage is +12V. The card programming voltage is controlled by the interface controller.
