I have located the Cray Y-MP EL, in addition to other other interesting items, including an Intergraph 6400 workstation with tablet, a PDP-11/23, an IBM System/34 with 5251 terminal and keyboard, a Unisys A-Series mainframe, and a Symbolics 3640 Lisp machine (includes console, but there is no keyboard).
Pictures can be found here: https://photos.app.goo.gl/rgkBddeuosjnJ3TC6 I am taking offers on all of the above listed items. Thomas Raguso
