Appendix IV:
An experienced users introduction to
the CPC464
The CPC464 is a low cost colour personal computer
with a generous,
effective and thorough implementation of established technologies,
presented in format designed
to offer
exceptionally attractive value
for money coupled with substantial capacity for expansion, and
thus be attractive to both first time and
experienced users.
The hardware and ROM software have been designed to provide newcomers and experienced
programmers with a friendly environment in which existing software may be tailored, and new
software written to take advantage of the many features supported by the CPC464.
The major features of the system are
:
Z80CPU
The most widely used microprocessor found in home computers throughout the world, and with the
best supported software base - especially since the CPC464 offers the potential for the
implementation of CP/M. The unique interrupt handling structure has enabled the CPC464 to
innovate with the BASIC features AFTER and EVERY, and other ‘real time’ facilities controlling
sound and timers.
64K RAM
A generous amount of RAM is supplied as standard, over 42K of which is actually available to the
user, thanks to the implementation of ROM overlay techniques when implementing the BASIC.
Screen
The CPC464 supports three basic screen handling modes, including 80 column text, a palette of 27
colours, and resolution up to 640x200 pixels.
