Most (all?) of you here probably know I resurrected the Steiner Synthasystem modular. Believe me, this is, and was never meant to be "for profit". That said, as I got the PCB layouts finalized, I bought some small runs of PCBs and so have some of all the modules (last three module's PCBs are on order) available to buy if you want a true re-issue of the original Steiner-Parker system.
Have a look and PM or email me (email on the site) any questions or comments you might have.
