A complete Definicon software set. Includes GreenHills C (K&R only), Fortran and Pascal compilers. Filenames are in mixed case. An assembler is made by the Computer Systems Design (Perth, Western Australia) and language compilers are from the Green Hills Software. Assembler is quite powerful and supports module concept for the 32000 (unlike many other assemblers including GAS). Also two alternative assemblers included. Object module format is proprietary. Executables *.e32 are in an a.out variant (loader sources is available in the LOAD sources).

This C compiler (tested under emulator) is trying to include a “system” HOST header files from the /usr/include. This does not work because of non-K&R syntax and complexity of the modern headers. Use a “local” header files (in double quotes) #include “stdio.h” in your sources.
(TODO: Make a “fake root” in emulator ?) C Compiler options: dsi32-copt

ln linker uses unusual syntax. It requires a special “definition file” (slightly similar to “response file” for a Microsoft's linker). Software distribution provides sample files with def or d32 extension.

Definicon software requires a DSI-32 card with real 32000 CPU installed in PC. In 2016 Dave Rand wrote an DSI-32 emulator using a 32016 software emulator from the Acorn 32016 Tube Coprocessor Board project:
https://github.com/hoglet67/PiTubeClient
https://github.com/hoglet67/PiTubeDirect

DSI-32 emulator:
http://ftp.berklix.org/~dlr/dsi/emu32k/

I did a slightly improved version:
- Renamed emulator executable file to “load” to conform DSI-32 name loader
- Added “file normalization” to translate ALL filenames to lowercase.
- Commented on service calls
- Many other small improvements (and new bugs)
http://wiki.sensi.org//download/ns32k/emu32k_load_10a.tgz

With this patch you can use lowercase filenames everywhere. File extensions is unnecessary. All options after -a are passed to the 32000 program (like as real LOAD.EXE).

./load cc -a -O -ge -X88 test.c
./load as -a test
./load ln -a file=test
./load test

A bash command to rename all files in the current directory to lowercase:

for i in *; do mv $i `echo $i | tr [:upper:] [:lower:]`; done

A mon2m is a symbolic debugger. To use a symbolic debugger you have to make a <name>.s32 file with linker directive symbol. Debugger will load it automatically. Second argument <name>.e32 is a program to debug. It becomes argv[0] argument. Symbolic names must start with . to inform the debugger that the string is a name and not a hexadecimal input:

./load ln -a file=test map symbol
./load mon2m test
*L._main
Module name = test.c, Symbol name = _main
008000  ENTER   [R3,R4,R5],H'0
008003  ADDR    H'0(SB),TOS
008009  CXP     _printf
00800B  CMPQD   H'0,TOS
00800D  ADDR    H'1C(SB),TOS
008013  CXP     _printf
008015  CMPQD   H'0,TOS
008017  ADDR    @H'7F,TOS
00801B  MOVD    H'DEAD,TOS

008025  ADDR    H'2E(SB),TOS
00802B  CXP     _printf
*

Trace does not work since not implemented in the 32016 emulator. TODO?

GENIX was a National Semiconductor's trademark for the UNIX-class OS for the NS32000 architecture. Early GENIX was a 4.xBSD port and later GENIX was a UNIX SYSV (R2 and R3) port. A significant number of workstations used this OS: i.e. Whitechapel Computer Works, Trinity Workstation and NS SYS32/20. There were also proprietary 32000 UNIX ports under it's own name (i.e. Sequent DYNIX, Siemens MX 300 SINIX, Encore UMAX, Tektronix UTek e.t.c)

Tilson, Michael (October 1983). “Moving Unix to New Machines”. BYTE. p. 266. An article about porting early UNIX to NS32000 architecture. Seems this is source of the “unreliability” opinion about NS32000 CPU.

Since GENIX 2 is based on the AT&T SYSVR2/3 hence most of documentation are suitable for GENIX 2 too.

1) http://bitsavers.trailing-edge.com/bits/AmericanInformationSystems/AIS_GENIXsrc_ 6-20-85.tar.gz
Early GENIX sources (derived from the 4.1BSD) for the DB16000 board. Also includes SNXC (early 32000 crosscompiler) for VAX 4.1BSD. An assembler sourcecode is written in Pascal (sic!). C compiler is PCC. Binary format is a.out (variant).

2) http://bitsavers.trailing-edge.com/bits/AmericanInformationSystems/AIS_oldUsr_10-3.cpio.gz
/usr cpio archive from a more recent GENIX (SYSVR2). Not sources. /usr/bin contains binaries in the ns32k COFF format (similar to the Opus binaries, see below). Some binaries are not stripped.

3) http://wiki.sensi.org/download/ns32k/SysVr2.0_32000.tgz
A full SYSVR2 sources ported for the NS32000 processor for National Semiconductor SYS16/SYS32 machines. Includes NS32000 assembler, loader and C compiler sources. This UNIX sources correspond to the well known SYSVR2 sources for VAX floating around: i.e. sysvr2-vax.cpio

as assembler is written in a “classic” LEX/YACC. Unusually, m4 is used as macro-processor. Unfortunately, this assembler is very “fragile” - it coredumps on a errors in the input file. Object format from this as and ld is COFF (ns32k variant). Assembler has a quite unusual syntax: all numerical constants and variables are treated as “absolute” (even without “@var”). According to some reports, this addressing mode works faster. The syntax for var(pc) (PC-relative) addressing mode is unknown.

Sources may be compiled under working SYSVR2 (i.e. SIMH/VAX or SIMH/3B2) to make a sort-of “crosstool”. It is possible to build it under relative old GCC too (I've successfully built it with GCC 2.7 on a i386 RedHat Linux 2.1 Bluesky, November 1995 under Virtualbox).

4) http://bitsavers.trailing-edge.com/bits/OpusSystems/Floppies/
Full binary distributive for the Opus5 card ( http://cpu-ns32k.net/Opus.html ) also know as National Semiconductor SYS32/20 Development Board. It's SYSVR2 (GENIX2). No sourcecode. Binaries are in the ns32k COFF format.

Siemens SINIX-H is an UNIX-class operating system for the Siemenx MX line of the computer based on the NS32000 CPU.

http://oldcomputers.dyndns.org/public/pub/rechner/siemens/mx-rm/index.html
Floppy images for SINIX-H. All floppy disks are copied twice: in Catweasel floppy backup hardware (*.DMK) and ImageFloppy tool (*.IMD). SINIX uses unusual 80-track SD/DD variable-density floppy: Track0 is in FM 16×128, while all another tracks 1-79 are in MFM 16×256. These images are bit-copy of tracks including sector's headers so you have to translate it to the raw-data format (w/o headers). Adam Sampson's dumpfloppy can extract individual tracks from the *.IMD files into raw format.

First 3 diskettes are bootable disks(?). Diskettes 005..006 is a kernel+miniroot(?) image. Diskette 004 and starting from Diskette 007 contains installation data as concatenated Install+Data tar files (Data tar starts at offset 0x6000) (Update: Diskette 013,014,020,021 contains productive kernel + root filesystem dump(?), not a tar). To extract diskettes:

SINIX uses a.out format (variant) with extensive use of ns32k architecture module feature. There is no known tools to examine this executebles.

National Semiconductor's SNXC16 (later known as NSX-32 and GNX (GENIX Native and Cross-Support)) was a cross tool including C, Fortran and Pascal compilers, linker, assembler and supporting tools. Assembler accepts an “old” or “classic” NS16000/32000 syntax.

Network was in the “embrionic” stage in the 4.1BSD. An emulated “tape” may be used to “import” and “export” between emulated OS and host. To extract a .tap SIMH tape image there is a “extracters/rawtap” ulility from the SIMH's utils:

NSXC16 Assembler Reference Manual

GNX v3 and v4 was intended for National Semiconductor's evaluation boards:
NSV-CG16-EDB, NSV-CG160-EDB, NSV-GX32-EDB, NSV-GX320-EDB, NSV-FX-GC-EDB, GC160LX-LBP, NSP-AM160-EDB, FX16FAX

There is very few information about these boards. I've found this article:

Take a GNX 4.4
http://oldcomputers-ddns.org/public/pub/rechner/national_semiconductors_series_32000/gnx/nsc-gnx-4.4_images.rar

Add the following options to the dosbox-0.74.conf (C:\Users\%USERNAME\AppData\Local\DOSBox) :

...
...
[autoexec]
# Lines in this section will be run at startup.
# You can put your MOUNT lines here.

set PATH=%PATH%;C:\GNX
C:

Extracted GNX 4.4 folder (Software\folder.gnx) into host i.e. C:\TEMP\GNX (programs sees it as C:\GNX inside DosBox)

DosBox provides 16MB of DOS XMS memory by default (GNX/MS-DOS uses built-in DOS Extender).

GNX v3 and v4 use relative modern COFF format (with debug info, modules support e.t.c). GNX4 cross-tools has a SYS5_2 and SYS5_3 (with shared libraries support) targets. “GNX Language tools 4” book has “COFF Programmers Guide” chapter.

GNX v4 C compiler supports ANSI C and function prototypes.
