This is one of the "New ACE Science Fiction Special Editions" edited by Terry Carr. Probably the starting point of the cyberpunk movement, but his second book, Count Zero, is much better (in my opinion). Actually, I still think the precursor for the cyberpunk movement is Brunner's Shockwave Rider.
Note: a pre-publication cover used different colors for the
graphics.
