Welcome to ELVIRA!



A sligthly modified version of Bob Supniks PDP11-emulator running RSTS/E:

Connect to ELVIRA port 4000, login as user: 99,99    password=user

(If you are using a broken win telnet client or c-kermit, press ESC instead of ENTER after user ppn
Update: Modified character mapping so the above should no be needed, please also note that "DEL" (=Ascii 127) is used to remove characters from input buffer, "BS" (=Ascii 8) does only backspace and does not remove character from buffer)

Operating system is RSTS/E V 8.0.
The emulator is now running on an AMD K6-2 300, so it is slightly faster than a real PDP11/73.

NOTE: disconnect is a bit slow after logout.

RSTS/E documentation for use with the emulator is here.

Some other RSTS/E related info here.
