Shop : Atari Eiffel interface for connecting a PS/2 mouse and Keyboard to your Mega

Atari Eiffel interface for connecting a PS/2 mouse and Keyboard :

Right after the ST-2-Mega adapter was designed i started investigating the Eiffel project a little further.
I stumbled upon this earlier but had no real use for it.
Now that i had purchased a keyboardless Mega , i needed a solution for using a mouse and a keyboard for that machine.
Since i already designed and use PS/2 keyboard and PS/2 mouse adapters on my Amiga 500 and 2000 it was more convenient to have a PS/2 connection then a ST keyboard adapter.
Therefore i started reading up this wonderful creation called Eiffel  interface.
Based on a PIC16f876 microcontroller this interface reads scancodes from the PS/2 devices and translates them to codes that the Atari ST can understand.
Standard functionality without a driver , scrollwheel support available with the use of a driver.

Atari Eiffel interface some History :
