The Atari Eiffel PS/2 comes as a DIY electronic project kit. Skills in soldering electronic components is required to complete this project. This project is simple to make and accessible for beginners in electronics.
If you rather buy a version with the components already soldered, see the Assembled version.
The Atari Eiffel PS/2 adapter allows you to connect a PS/2 keyboard and mouse to your Atari Mega ST(E) or Atari TT to the keyboard port (RJ12).
Although compatible in theory, the Atari Eiffel PS/2 adapter cannot be connected to an Atari STF or Atari STE which have an integrated keyboard, because it uses an RJ12 port (telephone cable) which the Atari STF and STE do not have. To use a PS/2 or USB mouse on an Atari STF or STE, rather use an adapter to plug into the joystick port instead.
This version of the adapter is a compact version (80mm x 35mm) without a joystick port, and only allows you to connect a keyboard and a mouse in PS/2 format.
I don’t recommend using a USB to PS/2 adapter to connect the mouse, as it doesn’t always work. Some say it works, but the tests I’ve done have never give good results. Preferably use a native PS/2 keyboard and mouse, with a ball or optical, both work.
The PIC microcontroler provided is already programed.
To connect the adapter to your Atari, you will need a RJ12 (6P6C) straight cable (not provided).
