Hmm I've been on the lookout for a DTC01 for years. This is tempting... but I probably should get a PRO first :) /P On Tue, May 20, 2014 at 05:04:39PM +0000, lee.gleason at comcast.net wrote: If anyone out there is hankering to have one, a DEC PRO telephone Voice Unit is on Ebay right now. http://www.ebay.com/itm/NASA-Digital-DEC-DTC11-B-Voice-Unit-Professional-30… -- Lee K.

Of course... :-( Anyway, I just realized/remembered that I'm not sure if the PRO was ever mentioned in the context of PDP-11 with graphics and sound. The PRO obviously always have grahpics. But there was also a sound option to it, which could interface with telephone systems. Not sure exactly how capable it was, but I have some blurb in a handbook somewhere. Johnny
