Yes. There's just a single programmable tuner, much more flexible.

I've got one and I made up a lead - though I cheated with the lead by
keeping seperate I/O lines and modifying the ATS ROM slightly, this
probably isn't neccessary but I followed the same layout as GC used with
the parallel port lead.

Hmmm, this is what I've got.

1      blue    8       pb1
2      green   5       0v
3
4      red     20      pb7
5      white   6       pb0

I suspect pb0 is input, pb1 is output (on the Morley and what ATS expects
by default, these are both on pb0 as a tristate line - try it by ignoring
the pb1 connection) and pb7 is the clock.
