I have a mess of Rainin Control/Interface modules. They are basically lab interfaces for controlling "stuff". I have no docs, and not much more idea of what they do beyond this simple description. I imagine they have some relays or optoisolators in them. If you know what they are and want a mess of them, make me an offer (privately please). -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]
