• Enable the secondary fire button on Commodore Amiga
computers if not automatically recognised
o The value of the surface mount resistor (R1) in the
ArcadeR has too high a value for some Amiga
computers to recognise the additional fire signals.
o For PCB version 1.5b, removal of this resistor and
replacing with wire, or a 0-ohm resistor will enable
the ArcadeR secondary fire button to work with an
Amiga.
o PCB version 1.5c has a jumper on the underside of
the board to bridge R1.
▪ Remove the circuit board from the ArcadeR to
access the underside.
▪ Install a jumper across the two-pin connection.
o Note: This modification is only necessary to utilise the
secondary fire button.
o IMPORTANT NOTE: bridging resistor R1 as mentioned
above is for the Amiga ONLY. Using an ArcadeR with
this modification on any other type of machine can
cause damage to that device.
