There were a whole bunch of slightly different makes of 1084, and at
least one version was *very* different from the others.

You should maybe ask Ray Carlsen on comp.sys.cbm, who is the
Internationally Accepted Guru (TM) for the finer points of Commodore
harwadare connectors, and also a pretty nice guy. He also has or (had) a
homepage somewhere with lots of info of that kind.

If your 1084 is not a 1084S (the S has stereo speakers) and it has a
covered hole on the back shaped like a SCART connector, the SCART is
fairly easy to retrofit. Connections are already on the PCB and all you
have to add besides the connector is something like two pieces of wire
and two resistors, all marked on the board IIRC. You will probably need
a schematic for this, though. The 1084S unfortunately uses the same area
of the PCB for connecting its stereo amplifier board, so it's not as
easy to convert to SCART as the plain 1084.
