Subject: Beebug buffered disk drive interface

Hi,
       I have a second hand Beebug Ltd (1990) Archimedes Disc Buffer
(Niche design 0480 214729). I am thinking of use this on another machine
to buffer disk signals from a longer cable i.e. from a BBC disk drive.
       The board consists of 1x SN74LS123N, 2x SN7207N, 1 x GAL and
selection of resisters & capacitors a power connector and dip switch
block plus IDE ribbon cable for input and a IDC socket for output.
       On the device is a 8 way dip switch selection switch. What I
need to know is what this selection switch does as I have no manuals
with the device?
Does anyone have a manual for the device or know what the selection
switch does?
       The original person I bought the unit from is unresponsive by
email so I am unable to contact him for advice. The unit work however on
its default settings.
       Default settings are 
                       Switch 1  2  3  4  5  6  7  8
                                0  1  0  1  1  1  1  0

Where 0 indicates off and 1 indicates on.

Thanks
Chris
