I have four three extra boards and panels (unassembled) for my version of Halting Problem (Kosmo Turing Machine clone), and also four three extras each for my versions of two expansion modules:
Not putting these on Tindie, but if you are interested in one or some or all give me a DM. $10 for the main module and $5 for each expansion sound good? Or trade for some other Kosmo stuff? Or, I dunno, you tell me. DM me. Payment via PayPal. Postage (to US) extra.
