Commodore 128D Pro Tip
If you are running out of space on your desk because of how large/deep the unit is you can move the unit to a shelf below and just extend the keyboard cable, or sit the 128D itself up on its side like a tower (assuming you 3D print some stabilizers to keep it from toppling over).
The keyboard uses a standard DB25 so you can extend it with a
Parallel/Serial Port extension cable so long as it is Male to Female!
So the keyboard can be quite far from the computer if need be.
I sold MattSoft my 128D Keyboard so depending upon if he kept it you might actually be using my old one, lol.
