Introduction
This PC is based on the Amstrad PC7386SX computer, using an 80386sx
processor. It has 1Mb of RAM (expandable on-board to 16Mb), and a
VGA controller capable of 640 x 480 resolution with 16 colours.
In addition to these standard PC functions, the PC also supports the
extended sound features of the Adiib sound synthesizer, and has a built-in
dual analog joystick port.
Butit is the last major feature which makes this machine unique in the PC
world. That is the ability to play not only PC-based games, but also the
highly successful arcade-based games in the Sega 16-Bit Mega Drive
cartridge format. Thatmakes yours a very MegaPCH

PC Operation Mode
Operation in this mode is exactly as for a normal PC and is described fuity
in the PC7386SX user manuai. The oniy part of the hardware not
described in the PC manual relates to the extra PC sound- system and
games port facilities.
PC Sound System
The range of sounds available from the PC's own internal speaker is
without o doubt very limited. Your MegaPC, though, has abuilt-in digital
FM sound synthesizer (Adiib soundcard compatible) which allows you
access to a whole new dimension in Pt) generated music and sound
effects.
The speakers for listening to the sounds produced by your MegaPC are
built Into your monitor, so there's no need for any trailing wires or loose
speakers. If you need a little more privacy, there is a headphone socket
at the rear of the machine for you to use. This will disable the monitor
speakers. The synthesizer sound volume is controlled by the slider at the
front of the machine. The PC speaker has its own independent volume
control.
Joystick/Games Port
The 15-way D-Type connector accepts any of the wide range of industry
standard analog joysticks currently available, The joystick supplied with
your machine Is precise and smooth In action, as well as easy to hold and
use. A digital joystick (which normally has a 9-way D-type connector) orily
has up. down, left, right and the four diagonals, but there are digital types
available that are compatible with the analog port.
Although there is only the one connection available at the rear of the
machine, it is possible to play dual joystick games by using a special
splitter cable. Contact your dealer to find out details of where you can
buy a ready-made cable.
Other Notes.
For all other points referring to the PC, plepse refer to the PC7386SX user
manual included in the keyboard pack. When reading this manual please
bear in mind that the sliding front panel must be fully engaged to the left.
