PDP-8s has been used for just about everything and have almost as many different front panels. This is one of the more esoteric ones I've seen: http://www.flickr.com/photos/joachimschwanter/414790437/ Is this a one off custom build? Rebuilt by a PDP-15 lover perhaps? Appearantly it was showcased at VCF Europe in 2008, maybe someone was there and can shed some light on it. Hope this is tech enough for cctech :) Cheers, Pontus.
