  • 18-bit Serial Card in 22-bit backplane

    From cli...@gmail.com@cliff52@gmail.com to alt.sys.pdp11 on Tue Nov 22 05:41:33 2022
    From Newsgroup: alt.sys.pdp11

    I'd like to run a DLV11-J (18-bit) in a H9270Q (22-bit) backplane. Haven't tried it yet but wondering what problems I might encounter. The CPU is KDJ11-AA so no serial or ROM there. I'm using a QBone in 22-bit mode for memory, serial port and ROM.

    DLV11-J is documented as working in a 22 bit backplane. It's an 18
    bit device, but it doesn't do DMA, so it's not a problem. See DEC
    Micronote #5.

    Lessee, what else....you need to put it in the highest priority slot
    (IO slot that is closest to CPU and memory), otherwise higher
    performance devices will keep it from getting much done. See DEC
    MicroNote #33.

    IF you plan to use VMS SYSGEN CONFIGURE to see what vector and
    address to use, you'll be out of luck, since DLV11J apparently isn't
    supported by that tool (been wrestling with that problem myself for a
    few days). What vector and address are you planning to use? If it
    conflicts with any existing ones in your machine, you may have some
    writewarp work in your future....

    Yes. Obviously. I have several of them. But the best tool for
    planning what CSRs and vectors to use for options on VAXes AND PDP11s is
    VMS SYSGEN CONFIGURE. You give it a list of options, and it will give
    you back a list of the CSRs and vectors to assign to them, following all
    of the configuration rules. It's a handy tool - for PDP11s as well as
    VAXes. It you're doing any hardware modifications to a system (yes,
    including KDJ11-AA and other PDP11s), you should check it out.

    And, although usually I wouldn't think it would be necessary - just
    in case I have to spell it out here - you run the tool on a VAX running
    VMS - even when you are using it to generate configuration info for a
    PDP-11. There is no VMS SYSGEN CONFIGURE available for the OS's
    generally found on a PDP-11.

    Glad you spelled it out. Thank you. Not everyone has a VAX available to configure a PDP11. I do but they run UNIX. Haven't had the time or the need to install VMS. Been kicking around the idea of dual booting a vax but don't have the heart to dive into that anytime soon. Any chance it was ported to Unix/Linux ? (or other OS's). Source code available?

    Actually, I've been doing a lot of searching about CONFIGURE
    lately,trying to find out why it doesn't seem to support the DLV11J, and
    I came across a UNIX implementation of it. Haven't used it, but it
    looks pretty good. Sources included. It's available lots of places,
    here's one - https://www.tuhs.org/Archive/Tools/Misc/sysgen.tar.Z

    There's one included with the simh tools as well.

    If you are running RSX, and have DECnet installed, then there is [200,200]FLOAT.CMD

    However, that one don't know about the DLV11-J.

    There is a basic C implementation that does the same as VMS SYSGEN also,
    which I compiled on my RSX system.
    However, that one *also* do not know about the DLV11.

    With that said, I believe the DLV11-J is what was used with the TU58
    commonly, so if you play based on that, you would end up correctly.

    .run sysgen
    Type device names one per line, optionally followed
    by a comma and a repeat count. Finish with EOF.
