  • Any Horizon users out there?

    From John@21:1/5 to All on Mon Dec 30 10:54:50 2024
    Just checking if there are any other Horizon owners lurking out there.

    Any recommendations for a good wood polish for the cabinet?

    Not regularly, as my N* Horizon has been in storage for a while

    Wouldn't know as my Horizon is a strange beast. It's a full complement
    of N* cards (CPU, 64K DRAM, FDC, HDC) plus a non-N* 32K SRAM card with
    a Vector Graphics BitStreamer-II (3-serial/2-parallel) standing in for
    the Horizon motherboard's UARTs in a 12-slot S-100 backplane all mounted
    in a 19-inch rack-mountable enclosure. 1 floppy drive and a 15MB hard
    disk.

    It originally had a bunch of custom I/O cards as it used to be the
    maintenance workstation for a Cray X/MP supercomputer. It boots
    both N* HDOS and/or CP/M 2.2. The CP/M hard-disk partitions are
    implemented as large HDOS file(s) so CP/M is actually running on
    top of HDOS.

    That's a nice setup.
    I'd like to get some of my systems rack mounted. But they are all
    desktop versions.
    I keep buying more desks as the collection expands!


    I'm using 'Orange Glo' wood polish at the moment.
    It works well and is absorbed by the wood in a day or so.
