Re: [TUHS] Depraz/Logitech Digimouse manual

I stuck an Arduino on it and with surprisingly little code I have it acting like a 3-button USB mouse. The only problem is that the pointer doesn't move smoothly. It does OK left-to-right, and can move down pretty well, but going up is a problem. I think pushing the mouse forward tends to move the ball away from the Y-axis wheel, and the old spring on the tensioner just doesn't have the gumption to hold that heavy ball bearing in any more. john ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Wednesday, August 4th, 2021 at 9:12 PM, ron minnich <rminnich(a)gmail.com> wrote: > John, you can see that "stick a bird on it" -> "stick an arduino on > > it" -> "stick a pi on it" has gone as you once predicted :-) > > On Wed, Aug 4, 2021 at 8:59 PM John Floren john(a)jfloren.net wrote: > > > ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ > > > > On Wednesday, August 4th, 2021 at 6:12 PM, Henry Bent henry.r.bent(a)gmail.com wrote: > > > > > On Wed, 4 Aug 2021 at 20:52, John Floren john(a)jfloren.net wrote: > > > > > > > Having just been given a Depraz mouse, I thought it would be fun to get it working on my modern computer. Since the DE9 connector is male rather than female as you usually see with serial mice, and given its age, I speculate that it might have a custom protocol; in any rate, plugging it into a USB-serial converter and and firing up picocom has given me nothing. > > > > > > > > Does anyone have a copy of a manual for it, or more information on how to interface with it? If I knew how it was wired and what the protocol looked like, I expect I could make an adapter pretty trivially using a microcontroller. > > > > > > This might be of some help? > > > > > > https://www.vcfed.org/forum/forum/technical-support/vintage-computer-hardwa… > > > > > > -Henry > > > > This looks great, thank you! > > > > john
