is widely considered the "Swiss Army Knife" of Morse code keyers, offering a staggering range of features from Winkeyer emulation to PS2 keyboard support. While the project is legendary, its versatility can make the initial hardware setup feel daunting. If you’re looking to "repack" this classic schematic into a cleaner, more efficient build, here is how to approach it. 1.
