The $35 dollar manual is the OEM manual which you probably don't need.
When I called up Archive to get my 2060Ss set up, they sent me a
little 5 or 6 page manual called something like Quick Setup Guide or
something (I'm at home so I don't have the thing in front of me).
This guide pertty much just shows the jumpers and what they are for,
which is really all you need to know in most cases.  I got mine free,
your mileage may vary.

Okay...the RxD/TxD jumper is really a little serial port used for
factory testing.  Not useful for anything else.

I don't remember what DIA and PEN stand for, but on the known-working-
under-SCO-Unix Archive 2060S I have here, neither is installed.

CF0-2 set, as I recall, the maximum block size that can be transfered
over the SCSI bus to the drive at one time (is that right?).  You are
currently set for 16K.  I had to set mine to 32K to get them to work
properly.  This setting is all jumpers shorted.

You are correct that ID0-ID2 are the SCSI address.  You are currently
set at ID 1.

Yes...if you mount it internally, you will need to terminate the
drive.  NOTE!  You will also have to remove the terminators from the
controller board.  They are located right next to the extrernal SCSI
connector on the 1452x's (x = {A,B}).

I don't recall the values of and sources for the terminators.  Ithink,
though, that you should be able to use the resistors that you remove
from the controller.

Hope this helps...
