‘The Original First-Week Engagements Of “Star Wars”’ article written by Michael Coate, from the ‘in70mm’ website.
The article can be read via the Internet Archive’s WayBack Machine, here:-

‘The Original 70mm Engagements Of “The Empire Strikes Back”’
‘Remembering “Return of the Jedi”’ (with some 70mm information)
