Johan Sahlberg has had some ME-16 expansion boards manufactured, based on a design I did that never saw the light of day. If you’re interested, contact him directly at f_l_y_h (at) hotmail.com. He has a very limited quantity available.
Work progresses slowly on the DSS-1 upgrade. However I have almost completed the design for the new processor daughterboard.
I’ll probably end up missing the 2017 self-imposed deadline unless a miracle happens.
