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 thin= k pushing the mouse forward tends to move the ball away from the Y-axis whe= el, and the old spring on the tensioner just doesn't have the gumption to h= old that heavy ball bearing in any more. john =E2=80=90=E2=80=90=E2=80=90=E2=80=90=E2=80=90=E2=80=90=E2=80=90 Original Me= ssage =E2=80=90=E2=80=90=E2=80=90=E2=80=90=E2=80=90=E2=80=90=E2=80=90 On Wednesday, August 4th, 2021 at 9:12 PM, ron minnich = 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@jfloren.net wrote: > > > =E2=80=90=E2=80=90=E2=80=90=E2=80=90=E2=80=90=E2=80=90=E2=80=90 Origina= l Message =E2=80=90=E2=80=90=E2=80=90=E2=80=90=E2=80=90=E2=80=90=E2=80= =90 > > > > On Wednesday, August 4th, 2021 at 6:12 PM, Henry Bent henry.r.bent@gmai= l.com wrote: > > > > > On Wed, 4 Aug 2021 at 20:52, John Floren john@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 rath= er than female as you usually see with serial mice, and given its age, I sp= eculate 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?
