Welcome to the Mind Dump

Welcome to Chris' Mind Dump — an unfiltered stream of half-formed ideas, questionable experiments, and the occasional stroke of brilliance.

This isn’t a polished tech journal. It’s a place for the things bouncing around in my head that need somewhere to land:

  • Retro computing deep dives (Commodore, Amiga, AS/400 — the good stuff)
  • Hardware mods and weird electronics projects
  • FPGA builds, usually way more complex than they need to be
  • Scripts and tools that solve exactly one problem but solve it well
  • Rants about IT, UX, and whatever else is breaking today

If you're into floppies that still spin, terminals that still blink, or just enjoy taking the long way through a wiring diagram — you'll probably feel at home here.

Expect the occasional side quest. I’m not promising consistency — just curiosity.

TN5250 Emulation on Raspberry Pi 5 with Auto Login & Auto Start

First we have to prepare the Pi's SD card! I'm doing this on a Mac but the process should be similar on a PC.

  • Download Rapberry Pi Imager
  • Launch the application and use the following:
  • Raspberry Pi Device: Raspberry Pi 5
  • Raspberry Pi OS: Raspberry Pi OS Lite (64-bit)

Once the card has been prepped go ahead and insert into the Raspberry Pi and connect the Pi to a keyboard and a monitor and power of course!

First lets get the font size just right!

sudo dpkg-reconfigure console-setup
  • Encoding: UTF-8
  • Character Set: Guess optimal
  • Terminus
  • 16x32
