SmallyMouse2 Cased USB to Quadrature mouse interface for Acorn/RISC OS Description:
SmallyMouse2 is a universal USB to quadrature mouse adapter for many 8-bit and 16-bit retro computers and allows the use of most USB mice on machines such as the Acorn BBC Micro, Acorn Master, Acorn Archimedes, Acorn RiscPC, Commodore Amiga, Atari ST and many more. Unlike most existing mouse adapters, SmallyMouse2 implements a fully USB compatible interface (most other adaptors are PS/2 based) this allows the use of any modern mice including those that use wireless communications.
Not suitable for the A3000, which has a slightly different socket, which the Smallymouse's plug will not fit into reliably. For a suitable version for the A3000 please see this

Copies of the source code and designs are available from ourselves on request.
