Help!
Just a few tips:
Terminators:
The terminators will be little rectangular packages (2mmX3mmX20mm).
There will be three of them and they will be very near the 50 pin
connector on the PC (pee-cee) board (the 'green card' you referred to).
They SHOULD be in sockets, allowing you to remove them. You can pull them
out with a pair of needle nose pliers or a toothpick, or anything small &
pointy – just don't get too violent trying to pull them out :^)
Tips about wiring and figuring out which way to plug in the cable:
The terminators and cables must be plugged in the right way.
Fortunately, they've made it easy.
The flat ribbon cable should be marked on one edge with red or some other
color. This indicates PIN 1, and it should always be hooked up to the SCSI
device so that it is closest to the little '1' that should be painted on
one edge of the 50 pin connector on the CD-ROM (or whatever).
If there is no number painted near the connectors on the device, PIN 1 of
almost ALL device is usually indicated by a white square painted around
one of the pins. If this is not visible, check the solder holes on the PC
board itself themselves – PIN 1 is almost always a different shape than
the other.
The terminators will indicate PIN 1 by having a small dot painted near the
pin that should be plugged into the corresponding pin on the device.
Tips on cabling & termination:
Your Amiga probably has a 25-pin SCSI connector. So, you will need the
following:
A cable (25-pin male [DB-25 style] to 50 pin male [Centronics style]) to
hook up to your external box. (A 'Standard' Mac SCSI interface cable)
If your box is a PASS-THRU (ie: it has 2 connectors on the outside), then
you SHOULD NOT terminate either device internally. Instead, leave them
unterminated, and use an EXTERNAL SCSI terminator. This would be plugged
into the other connector (the one NOT plugged into your computer).
The reason for this is threefold; 1. You can then plug in another device
in-line without having to take apart the box and remove the terminators.
