PDP-11/05

From owner, Daniel Daigle:

The DEC PDP-11/05 came in three versions: 11/05 was in a 5-1/4" tall box, but the 11/05N comes in a BA11-D box which is 10-1/2" tall, and the 11/05S had the BA11-K box which is also 10-1/2" tall (my machine is an 11/05S).
All of these variants were also produced as PDP-11/10, which is the same thing but DEC branded (11/05 were more intended for OEM branding by companies packaging them into their applications, such as what Tektronix did here.)
