A 1960s/early 1970s typeface. Shown in 1973 by Photoscript and later also by Typeshop as Disco. Coal (Walter Haettenschweiler, 1969) is a similar all-caps alphabet shown in Lettera 4 (1972).
Various digitizations including Disco (Softmaker, B&P, Brendel), Disandat (Brendel Informatik & SoftMaker, 1990–93), Outland (FontBank, 1990–93, used for the sample), Discotheque (WSI, 1993), D730-Deco aka Disco (Softmaker, 2002, all pretty similar), and Circular Saw (SWFTE, 1995).
Geodezyx NF (Nick’s Fonts, 2008) is a commercial version by Nick Curtis, who mentions Disco as his source. It appears to be less authentic in some details. Differences are most notably in ‘ajsS235’.
