INSTALLATION GUIDE
DISCLAIMER:
Before attempting the procedures outlined in this guide, please be advised
that neither Mr.Atari, nor the manufacturer of this device assume ANY LIABILITY
WHATSOEVER for damages caused directly or indirectly by the installation of this
product. By attempting these procedures, YOU AGREE to assume all responsability
and liability for any damages that may occur.
FURTHER NOTE:
This document also assumes that your 6502C CPU is installed in a high
quality, double-contact socket on your motherboard. A small percentage of XE
machines were built by ATARI with socketed CPUs. The vast majority of XE
machines, however, had the CPU chips soldered in place from the factory. The
MyIDE-XE kit does include a suitable socket for this purpose. The procedures for
removing a "soldered-in" CPU and replacing it with a socket are beyond the scope
of this text. Furthermore, this task is (in our oppinion) beyond the level of
what should be attempted by the average hobbyist. We reccomend referral of this
task to a professional electronics repair facility, or to a person very
experienced in removing and replacing "soldered-in" chips. DO NOT ATTEMPT TO
DESOLDER YOUR CPU FROM YOUR MOTHERBOARD UNLESS YOU ARE SURE YOU CAN HANDLE
IT.
STEP 1: INSTALL THE BOARD
First, remove your 6502C CPU from the socket.
There is an electrolytic capacitor directly to the left of the CPU socket. On
some XE machines, this capacitor is too tall, and could possibly interfere with
the bottom of the MyIDE-XE board. You can either replace this capacitor with a
shorter one of the same equivelancy, or just remove it entirely. This capacitor
is only used for the "audio-input" signal from the cartridge slot. VERY FEW
devices (if any) have ever made use of this signal. Possible exceptions are any
sort of audio sampler that plugs into the cartridge port and uses the TV/MONITOR
speaker as a "live audio monitor." I am not aware of any such devices currently
available for the 8-bit ATARI.
Next, carefully plug the MyIDE-XE board into the socket, making sure that all
pins go into the appropriate holes. The pins are designed to be very tight in
the socket. It is normal for quite a bit of insertion-force to be required, but
make absolutely sure that all of the pins are going in straight before applying
downward pressure.
Finally, solder the wire from the MyIDE-XE to pin 14 of the 74LS138 chip on
the motherboard.
STEP 2: FITTING THE DRIVE
You will need an IDE notebook to desktop interface adaptor such as the one
pictured above. You must supply +5Vdc and Ground to the adaptor board with wire
that is of adequate size to supply the drive motor. 14ga or larger wire is
reccomended. If you plan to power the drive from the ATARI's power supply, make
sure your power supply is rated at least 1.5A. Some newer power supplies for the
XE series were only rated at 1.0A. If you have one of these 1.0A power supplies,
try to find one from an 800XL or older XE that has the higher current
rating.
Place the drive in the exact position shown in the photos above, and drill
the two holes in the back casework for the drive mounting screws. Please make
sure that the drive is pushed all the way to the left, with the interface
adaptor board against the plastic cartridge slot boss. Also, make sure that the
hole (A) shown in the photo above is not covered by the drive. Otherwise, your
top case-half will not fit without modification.
FINAL STEP: CABLE CONNECTIONS
You will need a standard IDE cable. The picture above shows my custom
shortened IDE cable. It is approximately 5 inches long. I shortened this cable
to minimize the length of the IDE bus and make the cleanest possible
installation, but this is unnecessary. A standard desktop IDE cable works just
fine. Be sure and note the orientation of pin 1 on both ends of the cable. On
the MyIDE-XE board, pin 1 is located on the rightmost end of the connector. The
hardisk activity LED connector is located to the left of the CPU, as installed
on the MyIDE-XE board.
This is how my finished installations look. Yours may vary, but as long as
it works, and the case goes back together, it should be fine. Please refer to
Mr. Atari's other on-line guides for detailed instructions on how to format,
partition, and install operating systems and software on your drive. Thank you
for your interest/purchase, and best of luck to you from Mr. Atari and the
MyIDE-XE team.
