An I have DECtapes from this system. I recall at least one being labled DOS. Could the content of these tapes be of help? In that case I should make another effort to dump these tapes (I have dumped a few). /P > > /Mattis > > 2016-03-15 17:46 GMT+01:00 Bob Supnik <b...@supnik.org>: > > > I've pulled together the hardware pieces for the PDP-15/76 (PDP-15 with > > UC15 PDP-11 IO processor), so now it's time to consider what software can > > be run. > > > > The most likely candidate is XVM/DOS-15.
