( Part 2: Connecting your peripherals .... This section explains how the various peripherals, or add-ons, are connected to the CPC6128 system. Details concerning the use of these devices will be found in the appropriate sections ofthis manual. Joystick The AMSOFT joystick model JY2 is an additional item that you may wish to purchase if you are using the 6128 computer with games software which incorporates the facility for joystick control and 'firing'. Connect the plug fitted to the JY2 lead into the socket marked JOYSTICK on the computer. The 6128 can be used with two joysticks; the !?econd joystick should be plugged into the socket on the first joystick. The AMSOFT joystick model JY1 is also suitable for use with this computer. Further information onjoysticks will be found later in this manual. The AMSTRAD Light pen model LP-1 may be connected to this socket. Programs may be loaded from, or saved to tape instead of disc. The commands which instruct the computer to direct data to and from disc or tape are explained later in this manual. To connect your cassette unit to the 6128, you will require the AMSOFT CL1lead, or any other equivalent standard cassette-interconnecting lead. Insert the end of the lead with the larger (5-pin DIN) plug, into the socket marked TAPE on the computer. Insert the plug at the end of the Blue cable into the socket on your cassette unit marked REMOTE or REM. Insert the plug at the end of the Red cable into the socket on your cassette unit marked MIC, COMPUTER IN, or INPUT. Insert the plug at the end of the White cable into the socket on your cassette unit marked EAR, COMPUTER OUT, or OUTPUT. Foundation Course Chapter 1 Page 7
It is important to remember that the successful transfer of data between the 6128 and cassette is largely dependent upon the correct setting of the LEVEL or VOLUME control on your cassette unit. If you cannot seem to load or save programs properly, experiment with different LEVEL control positions until the optimum setting is found. Printer The 6128 may be used with any Centronics compatible parallel printer. If you intend to connect an AMSTRAD printer to the 6128, simply use the interconnecting lead provided with the printer. If you wish to use any other Centronics compatible printer, you will require the AMSOFT PL1 printer interconnecting lead. Connect the end of the lead which is fitted with the flat edge-connector plug, into the socket marked PRINTER at the rear ofthe computer. Connect the other end ofthe lead which is fitted with a Centronics style plug, into the socket at the rear of the printer. If the printer is equipped with security clips at each side ofthe socket, these may be clipped into the cut-outs at the side of the printer plug. Details of printer operation will be found later in this manual. A 2nd disc drive (AMSTRAD FD 1) The AMSTRAD FD1 may be added to the system as a 2nd disc drive. The advantages . o(a2-driVeSystem -wiICbe partlcuw.rlY-apparenCto the-regular CP/M user, since many programs are configured to run with the library program disc inserted in one drive, and the working data files stored on a disc in the second drive. Operation under CP/M always requires that a program be loaded from disc (there is no access to the ROM BASIC). Since CP/M allows the use of multiple files by an overlay technique that permits programs that are larger than the RAM memory, the actual library disc may contain so many program files that there is little workspace left for the data. Thanks to the versatility ofthe utilities provided with your 6128 system disc, you can do all necessary file maintenance; copying, erasing etc, on a single disc drive. However a second drive will certainly speed up these processes and reduce the scope for accidents. To connect the FD1 to the 6128, you will require the AMSOFT DI2 disc interconnecting lead.
