The technical stuff seems to finally converge to a phase that launching of the Retro-uC campaign is getting close. In the current state four product options are planned: a chip, a breadboardable board, a prototyping board and a stand-alone board with Arduino MEGA IO layout.

The details are given in my latest blog post. All feedback and suggestions for improvement are welcome here. Do realise I may only be able to reply when I'm back from FOSDEM next weekend.
