chjara wrote a small kernel in Ada, that was really exciting.

  @Moon reminds me, is there any kernels in Fortran?

  @lanodan https://en.wikipedia.org/wiki/PRIMOS apparently yes but I bet it still has a C core somewhere deep inside

    PRIMOS
    
    PRIMOS is a discontinued operating system developed during the 1970s by Prime Computer for its minicomputer systems. It rapidly gained popularity and by the mid-1980s was a serious contender as a mainline minicomputer operating system. With the advent of PCs and the decline of the minicomputer industry, Prime was forced out of the market in the early 1990s, and by the end of 2010 the trademarks for both PRIME and PRIMOS no longer existed.Prime had also offered a customizable real-time OS called RTOS. Internals One feature of PRIMOS was that it, like UNIX, was largely written in a high level language (with callable assembly language library functions available). At first, this language was FORTRAN IV, which was an odd choice from a pure computer science standpoint: no pointers, no if-then-else, no native string type, etc. FORTRAN was, however, the language most known to engineers, and engineers were a big market for Prime in their early years. The unusual choice of FORTRAN for the OS programming language had to do with the people who founded Prime. They had worked for Honeywell on a NASA project. FORTRAN was...

  @lanodan I found source code for PRIMOS but it's all in some kind of tape backup format I don't think I can read.

  @Moon Probably would have to use a Prime/PRIMOS emulator on those.

  Haha, no it doesn’t. No doubt it has some assembly-language though.
  They developed hardware optimized to run FORTRAN, including machine instructions that directly implemented FORTRAN’s distinctive 3-way branch operation.
  PRIMOS was all IBM-flavor computer tech. Big-endian, probably in EBCDIC. C was a separate project, from academia, being developed on DEC machines. Little-endian and ASCII.
  They didn’t talk to each other.
