The Norsk Data computer emulator project:

The first version of the emulator for the Norsk Data 16 bits computers is soon finished and will be available for download. The first version will emulate the instruction set of the ND-120CX CPU, but not including all the CX-instructions. It will be possible to run programs in 1-bank background mode and a number of the most frequently used monitor calls in SINTRAN III are emulated, including file system monitor calls. The next version of the emulator will run 2-bank programs with emulation of the Alternative Page Table mechanisms.

Versions for Linux and MS Windows are available.

The emulator is now able to run programs like MAC, NPL, QED, FTN, NRL, BRF-EDITOR and programs compiled with FTN and linked by NRL.

I am lacking a listing of the SINTRAN-III file system, some programs like QED and MAC are still using some old undocumented monitor calls which give me some problems, actually these monitor calls are invoked by an 163xxx instruction and not 153xxx.
These monitor calls comprise MON 20 (WCI?), MON 42 (open file), MON 15, MON 25.

If you have access to the code of these monitor calls or know the exact functionality, please mail it to me.
