Supplier who makes equipment for sale by a third party.
The equipment is usually disguised by the third party
with his own labels.
A program that supervises the computer's operation,
including handling I/O.
A 32-bit local bus that provides connections for 32-bit
add-in boards. The bus operates at an external clock
speed of the microprocessor (up to 33 MHz). PCI devices
are configured automatically by the system.
A removable media with various uses (such as disk drive,
network or fax/modem) for expanding your MW-520. It
should be used with the PCMCIA slot.
Either of the two sockets on the processor into which the
PCMCIA cards are placed (supports 16 and 32 bit).
A portion of the system's memory that is designed as a
temporary storage area for data and programs. RAM
includes conventional and extended memory.
A modem signal which indicates that a remote modem
has called (literally, "the phone is ringing").
An integrated circuit which takes a character of data
(eight bits in parallel), and transmits each bit serially over
an asynchronous communication channel. It also accepts
asynchronous data and provides a character to the device
in which the UART is installed.
