-# Arcade Trackball Mouse
+# Mouse-Trak Teensy conversion
 
-A completely unnecessary, but fun computer mouse using arcade components and a billiard ball.
+Got an old 1998 MOUSE-TRAK but the Z86 MCU seems fried.
 
-# Design Files
+I decided to just replace it with a teensy.
 
-All printed parts were designed in Fusion 360 and can be viewed and downloaded here: https://a360.co/2Rxvm0l
-Or find the STL files in the `Fab` folder.
+# How
+
+Later.
