My sister's father in law used to work for AT&T. He was based in England working as a project manager, but he travelled all over the place. Next time I see him I'll ask when he worked for them, since it was around 1983 that AT&T was broken up.
I started learning C just over two years ago (you beat me to it by 25 years), it was only recently that I put the two together.
I got a friend in Hong Kong that helps me run blastar.in and we do virtual machines in QEMU of old operating systems like IBM OS/2 2.0 and Windows NT 3.1 Advanced Server and each one has a Visual C++ or C compiler in it. Even some FORTRAN compiler as well.
He made this Windows NT 4.0 MIPS virtual machine using QEMU-MIPS and it has a Visual C++ for it that also does C90 I think. He compiled a version of Conway's Life in it for fun. There are these Watcom C/C++ compilers as well, Google for OpenWatcom for the free versions of them they exist for OS/2, DOS, and Windows compiling and I think they even use C90 standards.
We are trying to do retro software in QEMU virtual machines, we got a collection of Unix images between us like some old SunOS and Solaris stuff, etc. Got Solaris in QEMU-SPARC running for a bit but had problems with the network stack. Older versions work but Solaris 7 seems to have a NIC bug in the kernel.
My father worked for Western Electric, 1-ESS switches, had tried to turn them into minicomputers running Unix System V and other stuff by working with Bell Labs and other divisions. I think the 1983 breakup put a stop to that. He did some work on a DEC PDP I am not 100% sure but I think a PDP-11 or something using Unix. When I was young he introduced me to Dennis Richie, who told me to learn Unix and C when I was older. They even wanted to hire me at AT&T when I turned 18 in 1986, until the breakups prevented that. So in 1987 I was in college and took a C class, it helped me learn a lot of different languages out there. Sort of like learning Latin or Greek if you ask me.
My father died in 2010 of brain and lung cancer. But I am still trying to get things done. If you want to work on a project let me know, I might know others who know C90 and can join in via retro legacy programming.
