Abstract
The excessive usage of peripheral devices such as TTY's,
VDU's and printers, have a significant load on the frontend
processor of the Alcatel X83 minicomputer. Because of
this, the response time of the front-end processor to the
peripher~ls is excessive. This can also be attributed to
the fact that the peripherals have small buffers or no
buffers at all. These peripheral devices also operate at
slow speeds. A slow response time from the mini-computer
results in decreased productivity. The mini-computer does
not provide ports for parallel printers even though there
is an abundance of these type of printers. The
unavailability of a variety of interfaces on the minicomputer
makes the reconfiguration of the peripheral
network inflexible. Replacing the existing peripheral
equipment in order to overcome the above limitations will
be costly. This thesis describes the design, development
and implementation of a data buffer and interface
converter which would overcome the above mentioned
limitations.
