Connect the end of the lead which is fitted with the larger edge-connector plug, into
the socket marked DISC DRIVE 2 at the rear ofthe computer.
Connect the other end ofthe lead which is fitted with a smaller plug, into the socket at
the rear of the FD1 disc drive.
DON'T FORGET - Before connecting or disconnecting the 2nd disc drive, make sure
that any discs are removed from both drives, and that the system is switched off. If
connections are altered while the system is on, it is likely that the program in the
computer's memory will be corrupted. Always save any valuable programs before
meddling with connections!
When the FD1 is connected to the 6128, FIRST switch on theFD1 using the slide
switch on the rear panel of the disc drive, THEN switch on the 6128 using the slide
switch on the rear panel of the computer. Both the green and red indicators on the
front panel of the FD1 should be illuminated. The 2-drive system will then be ready to
operate.
Details of2-drive operation will be found later in this manual.
External amplifier/speakers
The 6128 may be connected to a stereo amplifier and speakers to enjoy the full
3-channel capabilities of the computer.
The input lead to your stereo amplifier should be terminated with a 3.5mm stereo
jack plug, which should be inserted into the socket marked STEREO on the computer.
The connections to the jack plug are:
Plug tip - Left channel
Plug inner ring - Right channel
Plug rear shaft - Ground (Common)
The 6128 will provide a fixed voltage signal out of the STEREO socket, and you should
therefore use the controls on the amplifier itself to regulate volume, balance and
tone.
High impedance headphones will also operate with the 6128, however the volume
will not be adjustable by the VOLUME control on the computer. Low impedance
headphones, such as those usually used with stereo systems, will not operate directly
plugged into the computer.
Details concerning the directing of sound to the required output channel will be found
later in this manual.
