This project came about as we have all of these 'redundant' PSX controllers everywhere, and they're not actually that bad if the truth be known.  The joysticks which we had in the 1980s aren't really suitable for fast positive movements, unless of course we're talking about the arcade style ones made out of metal and weighted down to the ground.  Which is where JeST comes in.  You plug JeST into your computer, and the PSX controller plugs into JeST.  The project adds a great deal of functionality to the standard joystick where you can completely reprogram the button assignments and save different user setups for later use.

If there is one thing that Microsoft has wholly excelled at then it's their mice!  The mice of the 1980s were quite poor if the truth be known, that and certainly today they're quite difficult to find.  You really will notice the difference when comparing the two side by side.  PeST enables you to use a modern PS2 style mouse with the Atari ST, with the preference here being the 'Microsoft Wheel Mouse Optical 1.1A' as it appears to be the benchmark.  Scaling is greatly enhanced, and the wheel is used to action a drag-and-drop feature or to change speed of the pointer.  Most PS2 input devices can be used, as can their USB (with a PS2 feature) equivalents.  PeST has been about since 2004 and to date there's about 200 of them across the world.

The most difficult bit here is the soldering, which requires the ability to individually solder pads on a 1.27mm (0.05") pitch.  Once you can do that, then you can do it.  For the most part it's little more than connecting wires to the right place.  You will need a Fast Page SIMM and not an EDO SIMM, which is why it is recommended that you build a test socket to get things up and running.  Thereafter you fit the SIMM in permenently.  I also fit an external switch to allow the ST to be taken back down to 1Mbyte, as some applications hit the 4Mbyte ceiling (bad programming) which produces a hardware error and crashes the machine.

Flickr is used here to host the big images, mainly as they're set up to do it and they do it well.  It also gets them out there and into the public domain for others to see.  Quite often there will be more images uploaded to Flickr than are referenced here.
