Disk hardware

Here is a new update.  There are some new puzzles where you get to read and write to the (simulated) hard disk with low, low level I/O commands.  Can you build your own file system?

For this version, the installer was replaced with a zip file. This will work better for people who are using the itch.app.   If you are just downloading the zip from the website: unpack somewhere and double-click TX-15.exe.
