11LOGO

Hello, I have a 1972 version of 11LOGO, which is the dialect of Logo which was done by the Logo group at MIT. Their computer was a PDP-11/45. I have it running in a PDP-11 simulator, 11SIM, which runs on the ITS operating system. If someone is interested in running it in some other simulator like SIMH, I can provide files and assistance. The nice thing about 11SIM is that it emulates the one-off TK display system which provides 8 vector displays. 11LOGO uses it to view turtle graphics. It would be interesting to add this capability to SIMH, but I'm pressed for time. I can provide documentation, though. There is a second application, the Dazzle Dart game, which uses this display as well. It doesn't run in 11SIM because it uses FP11 instructions which are not implemented. Best regards, Lars Brinkhoff
