- /* machine description file for Gould PowerNodes with UTX/32 2.0 and 2.1.
- (See MACHINES for older versions.)
-
- * NOTE: If you are running a pre-release of UTX/32 2.1 you should #define
- * RELEASE2_1 in config.h. This may also be necessary with un-updated
- * official releases of 2.1

- /* The following line tells the configuration script what sort of
- operating system this machine is likely to run.
- USUAL-OPSYS="note"
-
- NOTE-START
- Gould Power Node (-machine=gould -opsystem=bsd4-2 or bsd4-3)
- (gould.h; s-bsd4-2.h or s-bsd4-3.h)
-
- 18.36 worked on versions 1.2 and 2.0 of the operating system.
-
- On UTX/32 2.0, use -opsystem=bsd4-3
-
- On UTX/32 1.2 and UTX/32S 1.0, use -opsystem=bsd4-2 and note that compiling
- lib-src/sorted-doc tickles a compiler bug: remove the -g flag to cc in the
- makefile.
-
- UTX/32 1.3 has a bug in the bcopy library routine. Fix it by
- #undef BSTRING in gould.h.
-
- Version 19 incorporates support for releases 2.1 and later of UTX/32.
- A site running a pre-release of 2.1 should #define RELEASE2_1 in config.h.
