It was a Sony News Workstation, with an IBM branded grey scale monitor displaying 16 grey levels at 150 pixels an inch. Total display was about 1900x3600, a bit larger than an opened two-page newspaper spread. It was a CRT monitor, requiring two feet behind the screen for the back of the monitor and quite thick cabling. It was a Unix workstation, used to author R&D CD ROMs, back when the CD ROM itself was R&D.
