Internal harddisk for EX5
This document is meant to help
everyone willing to install the internal harddisk for Yamaha EX5.
It's quite easy when you know
what you are doing, but you can damage EX5 and/or HD permanently
if you dont!!
Required before installation:
(For additional info, please check Michael Gerber's document "Internal

- ASIB1 SCSI interface.
- Two power cables (named A and
B in this document) [included in ASIB1].
- Harddisk power cable [not included

- Frame for harddisk.
- Screws to install the frame.
1. Power cable
The power supply inside the

existing power cable for harddisk,
so special cable have to be done to get the power for HD.
Figures 1-3 shows the
Figures 4-6 illustrates
how to connect those cables together.
2. Harddisk frame
Figure 7. Because there
is no any suitable stands or racks where to install the
HD but only a free space, a
harddisk frame is needed. The only requirements
are that it's small enough to
fit in its place and that there is possible to drill holes
where to get it connected to

in the power supply where to connect the
own power cable. It also shows
where to find the internal SCSI connector
Figure 10 illustrates
the installation of HD-frame. HD-frame is screwed to it's
place in one side. Cable tie
is used in the other side.
Figure 11. Before connecting
the own power cable one of the existing connectors
must be detached. There is only
two connected wires so using the other two that
