    Took some up-to-date photos of #SHORK 486 #Linux on my #IBM #ThinkPad 365ED, demonstrating kernel 7.2-rc working with 486/586 support patched back in! More photos: ftp.sharktastica.co.uk/shork-linux/...

A photo of an IBM ThinkPad 365ED running SHORK 486 with the SHORKMATRIX screensaver running. It is a "digital rain" screensaver where random characters are illuminated by falling blue/cyan droplets. A photo of an IBM ThinkPad 365ED running SHORK 486 with tmux "multiplexing" three "windows". The top-left window is running Vim and editing a C source file. The bottom-left window is running nano and editing a Gfortran source file. The right window has just compiled and run a C program with the Tiny C Compiler.

    A productive start of the week for #SHORK 486 #Linux with Cscope, Ctags, dialog, Indent, Make & NASM compiled and tested! There was also "budget" to enable 33 new BusyBox coreutils. All can now be tried from the PT1 branch! Here are all the available commands on a Plus build as of tonight!

    The #SHORK #Linux build script now has an option to configure SHORK 486 for serial console usage for you! Here's a demonstration of it...

    A screen captured demonstration of SHORK 486's serial console. A VMware VM with SHORK 486 is started. Then I switch to a terminal window on the host computer to use socat to connect to it through ttyS0. I then try some SHORKUTILS and SHORKOFF the system. ▶

    #SHORK 486 #Linux has finally got Vim! Wasn't so easy since it turns out it's a RAM hog on 486 levels of RAM... If you have 16MiB RAM + 16 swap, 24+8 or 32, it's fine. Otherwise, opening files that trigger syntax highlighting is too much... To fix, SHORK automatically creates a swapfile for Vim.

    #SHORK 486 #Linux will be getting some minesweeper! I found an interesting implementation, terminal-mines by Joel Ekström, that I forked, simplified given the target platform and added SHORK's visual cues. Available with SHORK soon! github.com/SharktasticA...

    A quick demo of the WIP #SHORK INSTALLER (shorkstall). If your system is too old to boot a CD, you can at least use SHORK DISKETTE as a boot disk, mount the SHORK DISC CD with it, and still run shorkstall. Note: on real 486 hardware, it won't be as fast as this...

    #Linux #kernel 7.2-rc1 on #SHORK 486 now in testing with restored 586 and x87 math emulation support! SHORK DISC is now available for building and burning SHORK to a CD - just make sure you have an El Torito-compatible BIOS. SHORK DISC will soon serve as the basis for SHORK 486's installation media.
