Another Java panel simulation for BlinkenBone is there, the classic PDP-11/20. In function and style it fills the gap between the PDP-8 and the later PDP-11's. The GitHub distribution starts the 1970 Paper-tape BASIC, download here: https://github.com/j-hoppe/BlinkenBone/releases Info http://retrocmp.com/projects/blinkenbone/simulated-panels/253-blinkenbone-s… and next page. Now we have PDP-8/I, PDP-11/20, PDP-11/40, PDP-11/70 and PDP-10/KI10. Not to mention the PiDP8 replica and soon the PiDP11. Joerg
