itself has become a bit cluttered; so here is a separate one to
describe the various plug-in modules.
||« This is a photograph of the D16/M Main Memory and Bus Terminator Module. It carries 64K words of CMOS RAM, 32K words of EPROM, and termination resistors for the D16/M bus.|
|« Here is the
Serial/Parallel I/O Module. It provides two RS-232 compatible
serial ports and two Centronics-compatible printer ports, and supports
either polled or interrupt-driven operation.
|« This is the new SD Card
Interface Module. It allows the D16/M to access up to four SD
flash memory cards, using a hardware- driven implementation of the SPI
serial protocol . There is a 32 MB SD card plugged into Unit 0,
the socket on the left.
