Another post to simply create a mind dump in case I ever need to / want to do this again!

I recently found myself restoring an old CompuAdd 810 (XT Clone). I was able to get it up and running and also at in an XT-IDE card running the latest Universal Firmware. Long story short, I needed to run the Firmware Configuration tool and make sure that I set the device type to Rev 1 (Compatbility Mode) in order for things work.

So now I've got a working XT Clone with a Hard Drive and DOS 6.22 installed. What to do next? Of course I can't play DOOM or Wolfenstein but there are some other nostalgic games that this machine can run such as Tetris, Pac-Man, Digger, Prince of Persia, just to name a few.

The tough part is getting them from my Mac to the PC. A lot of the utilities and OS's come as ready to write disk images, while the games are unfortunately just a bunch of files in a folder ususally.

So I needed a quick and easy way to create Floppy Disk images on a Mac!

If you're like me and you have a handful of static IP's and want to host multiple servers behind a router such as web servers, minecraft servers, gitlab servers, etc.. you'll need to put in some work. Initially I thought this wouldn't be possible with the EdgeRouter X but I finally got it working. I'm going to throw out some example IP's and an example setup which should allow anyone to adapt this to their own!

Public IP Space: 10.1.1.240/29 Private IP Space: 192.168.1.0/24

Start by logging into your EdgeMAX EdgeRouter X and head to the Dashboard

Typically eth0 would be your Internet connection, this is where we will define our WAN addresses:

• Actions -> Config
• Click Add IP
• Select Manually define IP address
• Add one of your WAN IP's
• Repeat for each WAN IP address you have
• Click Save

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

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.
