I've also noticed that the FCC ticket machines at SPILL have blank
circular plates - I presume that they will be converted to Oyster pads
in due course (so far I've yet to discover any Oyster-compatible
machines that were not built by Cubic).

You want non-Cubic ticket machines that do Oyster eh?!

London Overground has both Scheidt & Bachmann Ticket Xpress...

....and Shere Fast Ticket machines...

....which have both been adapted to to include an Oyster reader (can't
find any photos so perhaps I'll take some).

I'm pretty sure all the Shere machines were installed after the
decision had been made to let TfL take over the Silverlink Metro
routes, but whilst Silverlink was still in charge. The Scheidt &
Bachmann machines are as found at ex-Silverlink County stations, so
they were definitely Silverlink's choice of self-service ticket
machine.

The preference of TfL for the Shere machines perhaps makes sense -
they are certainly the more elegant solution when fitted with Oyster
readers, the readers on the S&D machines look a bit like a bit boil
that's just been stuck on.
