when [John Floren] Acquiring an old Depraz mouse, he began to be content with such a great history.But if you are like him, you know just have something.What would it look like use it?
To understand, [John] Started the task of building a USB adapter for his not-so-new peripherals.
The Depraz mouse was originally used in very early terminals with a Unix GUI, and it used the unusual male DE9 connector instead of the female DB9 used in the more familiar RS232 serial mouse. Deviating further from the specification, he found that the quadrature encoder was directly connected to the DE9 connector.
With the Arduino Pro Mini and some wrong sample codes, he started to work.The problematic code mentioned earlier is discarded, a New sketch of Arduino Pro Mini Depraz mouse is provided with a USB interface that it lacks. [John] It was also discovered that he was not the first hardware hacker to modify the mouse for their use. Be sure to read the end of the article to understand the retro surprises lurking in the mouse shell! You can see the mouse operation demonstration in the video below the interruption.
Looking for an interesting mouse hacker? Maybe you want to use a more modern USB mouse on a retro computer, or try to recreate an earlier Apple mouse used on a modern computer.
