The guy who gave them to me related that the PDP-6 had been decommisioned circa early 80's (replaced with a FOONLY - that ought to narrow it down for you!), and he was keeping KS10's and Massbus disk and tapes drive running in his house through most of the 90's :-). I'm not sure why I'm making any attempt at obfuscating this guy's identity, I gave away so many clues above that it's obvious who it is by now! Maybe my obfuscation is a lame attempt at stopping the "you tore up a PDP-6" blame game. Tim.
