Prior to the VAX line, you could get quite acceptable performance out of a PDP-11 running RSX11-M with 5-10 users and 256kB running on a pair of removable 10Mb disks - of course this was using character based terminals like VT-100's but you could do quite a lot of graphics using vector based devices like the Tektronics 4006 etc... see ftp.emgsrus.com/pictures/lab02.jpg for a picture of an 11/23 running a real-time video data collection system (7 cameras) and 3 terminals.
