I have been having trouble running some GT40 software with this. Turns out one crucial detail is missing: An interrupt vector for the VT11. Apparenty the ROM and Lunar Lander don't use the VT11 interrupt, but some other software does. With the addition of set vt vec=320 those programs work too. This conflicts with the DZ11 device which is enabled by default; it's not part of the GT40 hardware so just remove it. Now the GT40 can be used with Emacs and Spacewar. _______________________________________________ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
