I have had it successfully boot from the TU60 tape drive. The plan is now to attach a contemporary console terminal to it. I happen to have a LA30P which looks suitable and would make it a nice looking system. I have documented the effort here: http://www.datormuseum.se/computers/digital-equipment-corporation/pdp- 11-04 The LA30 is now working fine but the problem is that I don't have the M7910 or M791 card that make up the LC11 Unibus option as this terminal was once upon a time connected to a PDP-8/E instead. Is there anyone that have a M7910 or M791 card who wants to sell or trade it for something? During the restoration process of the LA30 I found that it is using quite uncommon paper. I needs 9-7/8 inch (250 mm) wide paper. Is there a source for this kind of paper somewhere else than in the USA? If there is no M791 or M7910 available I have to either make my own M791 or make a serial / parallel converter to go into the LA30P (I guess that no one has the M7389 and M7731 boards that make it a LA30S, or?). When looking for more information on the LC11, there were limited amount available on the net. I did find the LC11 Decwriter System Manuel (pages 4-2 and 4-3 was missing which is quite annoying) but not the LC11 Decwriter System Engineering Drawings. Anyone knows an online source for that one? /Mattis
