Printer; A 2Nd Disc Drive (Amstrad Fd 1) - AMSTRAD cpc 6128 User Instruction

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

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 inter-
connecting lead.
