I have revived my CH Mach III twice now with DeoxIT on the potentiometers. I've owned that stick for over 30 years at this point.

P.S. I wish someone made a modern joystick with a similar feel, but more than two buttons.

The CH Mach III looks tight! I was messing around with a DOS game Sword of the Samurai and was wondering what types of sticks were being used by enthusiasts at the time since that game supported a joystick.

What kind of things were you playing with that when you purchased it new? I'm in this industry in no small part to watching my brother play Descent with a joystick in the 90s. I think his was made by the same company - F-16 Flightstick. I remember it having suction cups on the bottom though

New would have been Chuck Yeager's Advanced Flight Trainer various EPYX sports games (e.g. Winter Games & California Games) A bit later would be Wing Commander and Traffic Department 2192. Even later (besides several Wing Commander sequels and spinoffs) Tyrian, One Must Fall 2097, and Duke Nukem 3D (keyboard & joystick instead of keyboard & mouse).

That works quite well, but I had to repeat it a few months later. I recommend cleaning also the other stick as the plastic in the DS4 casing can break from opening it too often.
