Has there been any recent RETRO action?

I haven’t seen any since the launch competition.

Not much there sadly

That’s too bad.

I have tinkered a little recently with the RETRO.

Unfortunately it seems that GHI/outrageous circuits no longer keep the firmware up to date with the evolution of mbed. Not a train smash, but unfortunate because it is a really fun platform.
