This listing is for:

This is the long version of the PS2MouseMini from Stuart Tyrrell Developments. It converts PS2 mice to the Acorn protocol and connector. It will convert any PS2 mouse. It has an Acorn mouse plug on one end and a PS2 socket on the other.

This one is new; a spare that is now surplus to requirements.

It works with 3 button mice and also wheel mice, where the wheel can be configured as a scroll wheel or just a button if you prefer.

No driver needed for the simple like-for-like replacement, but RISC OS pre-dates scroll wheels so a driver/patch is required from STD's web site for earlier OSes. Later Select/Adjust and RISC OS 6 support scroll wheel as standard with this interface.

I also have available an original Acorn mouse - see my other listings.

Particularly suitable for the A3000 because it allows you to bring the PS2 socket out to the back rather than connecting underneath. Also compatible with the RISC PC, and earlier Archimedes range, or any of Acorn's ARM based machines except for the A7000/A7000+.  See other listing for original shorter version.

Not suitable non-Acorn computers.
