  1. Dracula rises again: my 1980 text adventure, rebuilt from the EXE

    9 min #retro #basic #text-adventure #reverse-engineering

    Someone who played my Dutch text adventure Dracula as a child reverse-engineered it. The same night I got the BASIC source back from the old EXE with Claude, and ported it to C.

  2. Back to Unix V6, on a PiDP-11/70 with my own VT100 and LA120

    6 min #retro #pdp-11 #unix

    I built a PiDP-11/70, hooked up a real VT100 and LA120 over USB-serial, and patched the V6 kernel until backspace behaved.

  3. Retrotractor: A head gasket story on my MF133's Perkins A3.144 fixed with AI

    7 min #tractor #massey-ferguson #perkins #diesel

    My Massey Ferguson 133 lost power and ran on two cylinders. The compression test pointed at a valve; with the head off it was the head gasket.
