Hi guys, There is now a special 11/40 adapter board for the BlinkenBone system. With that you can plug a physical 11/40 panel to the extended SimH running on a BeagleBone. Surprisingly there was some demand for the 11/70 panel adapter, so adding the '40 panel may be worth mentioning. There is no own '40 documentation, see again the 11/70: http://www.retrocmp.com/projects/blinkenbone/physical-pdp-11-70-panels/288-… If you want it: I made the '40 ?10 cheaper then the '70. Entry to far-too-many web pages here: http://retrocmp.com/projects/blinkenbone All in all there are now at least 6 different (but compatible) ways to get a blinking PDP-11's with SimH. - Connect a real 11/40 or 11/70 panel. http://retrocmp.com/projects/blinkenbone/physical-pdp-11-70-panels - Run the virtual Java panels for 11/20, 11/40 or 11/70, also with play isntruction for the physical ones: http://retrocmp.com/projects/blinkenbone/simulated-panels/253-blinkenbone-s… http://retrocmp.com/projects/blinkenbone/simulated-panels/254-blinkenbone-p… http://retrocmp.com/projects/blinkenbone/simulated-panels/252-blinkenbone-p… http://retrocmp.com/projects/blinkenbone/simulated-panels/247-blinkenbone-s… http://retrocmp.com/projects/blinkenbone/simulated-panels/243-blinkenbone-p… Download & run from github https://github.com/j-hoppe/BlinkenBone/releases - get Oscars Vermeulens PiDP11 http://obsolescence.wixsite.com/obsolescence/pidp-11 I will be at VCFPNW in Seattle with that stuff. kind regards, Joerg
