    Hello everyone, hope yourCOre all keeping safe and well!
    IrCOm a first-time poster here and a recent, but very enthusiastic, fan of the PDP-11. I have started a blog to track my journey of discovery (https://www.learningpdp11.com/) and I would love to get some feedback. For those of you that are also members of the PiDP-11 forum, I posted there first because it was the only forum I was aware of, but now I'm reaching out to some other forums that I have found.
    There is a lot of information on the blog that I havenrCOt been able to find anywhere else (e.g. an instruction-by-instruction breakdown of the bootstrap loader and the absolute loader). Right now IrCOm working on a complete line-by-line breakdown of the PDP-11 BASIC application.
    Hopefully itrCOs a useful resource for those who like getting really low level understanding, like machine code/assembly stuff.
    IrCOm sharing this link here beacuse I thought it might be of interest to some of you and if anyone has suggestions, either for topics yourCOd like me to cover orrCawell, anything really, IrCOd love to hear!
    Thanks!

    complete line-by-line breakdown of the PDP-11 BASIC application.

    What flavor of BASIC for which operating system?

    ISTR that DEC had different BASIC language implementations for the
    different operating systems.

    OIC now, this is a standalone BASIC implementation that *is* the
    operating system. OK...

    It's possibly the original PDP-11 BASIC. I was given a copy of the source listings back in the seventies. IIRC it was written at Dartmouth College, the home of BASIC, under a contract from DEC, and I think it used IOX, the "Input/Output Executive" package for I/O. DEC provided source for IOX and
    for FPMP, the floating point package.
