CoCo3: Tandy TRS-80 Color Computer 3
These were obviously versions sold in Australia - nothing to indicate they
were special for this market though.
I have the CoCo3 Service Manual, and the Australian version is very
different to the US version. To get PAL video out of it, they ignored the
composite output from the GIME chip and fitted a PAL encoder board
connected to the RGB outputs (which also went to the RGB connector of
course). The mainboard layout is different, the clock crystal and, IIRC,
BASIC ROM, ara also changed.
Of course the name is almost certain to be unchanged.
