Despite Gould’s location being a few minutes drive from where I first arrived in America, I never had any idea they existed, were making their own exciting machines, or were even a Unix VAR. At a time during the Unix wars one was left to choose SYSV or BSD, but Gould had gone another direction with UTX with a ‘why not both’ approach. Truly an 80’s miracle of Unix.
Even better he’s included tape images, and working INI files which I was able to make into a working system! (after some help with a tape bug)

It’s very BSD feeling on the boot and in the /usr directory there is 5bin 5lib
Sadly transferring stuff by just pasting on the console reveals that there is some IO issues in the simulator:
syncing disks... done dumping to dev 101, offset 11776 ioi: channel dc0 at 800 online dump succeeded
As a matter of fact doing anything too fast can/will panic the simulator. That goes for Ethernet and additional serial ports.
Interesting highlights of the platform:
Produced by hard-params version 4.1, CWI, Amsterdam Compiler does not claim to be ANSI C Char = 8 bits, signed Short=16 int=32 long=32 float=32 double=64 bits Char pointers = 32 bits Int pointers = 32 bits Alignments used for char=1 short=2 int=4 long=4 Character order: short: AB int: ABCD long: ABCD
Obvious issues with the platform is a lack of GCC. The PCC compiler while standard for early 80’s non PDP-11/VAX machines is a bit lacking as the years went on. I was unable to build gzip due to the following error:
# gmake cc -o gzip gzip.o zip.o deflate.o trees.o bits.o unzip.o inflate.o util.o crypt.o lzw.o unlzw.o unpack.o unlzh.o getopt.o ld: warning: near subsegments too big for static base spanning ld: gzip.o: no base for reloc of memref instruction at .nbtext+0x18 relative to symbol _progname ld: 1221 more 'no base ' errors gmake: *** [gzip] Error 4
The constraints on address space on a Gould are quite severe.
Bummer. Additionally neither Hack 1.0/1.03 or PDP-11 Hack will build either. Surprisingly bash-1.14.7, make-3.75 and ircii-2.5 compiled. Obviously with no networking IRC is kind of pointless.
It’s an interesting time capsule of life outside of AT&T/CSRG or SUN, going in a different direction. It seems like a larger lost opportunity to take their ‘it runs both’ approach software and not have it available on different platforms. Granted for a hardware company once the software leaves the compelling reason to buy the hardware evaporates. Hello NeXT.
If anyone wants to try to re-create it, download and build the SEL32 emulator from github, and I put my vague instructions here.
Or for like minded OS tourists, you can give it a spin here: UTX32_2.1B.7z. I included a ‘9346-UTX-blank.disk’ file which is already prepared if you don’t want to go through the 15 questions to prep a disk. Likewise I made a ‘9346-UTX-biga-blank.disk’ image which is just a single large ‘a’ partition as it’s trivial to just add a bunch of big disks these days.
Full 32bit Unix machines from Ft Lauderdale! Who knew?
