The RCBus is an extended version of the RC2014^TM bus, designed to overcome the limitations of the RC2014^TM bus. The bus extensions and formal specification have been developed by members of the retro-computing community via the retro-comp forum.

The RCBus specification v1.0 is available below.

RCBus forum: retro-comp google group.

The RCBus exists for these reasons:

• To overcome limitation of the RC2014^TM bus
• To help clarify what is a genuine RC2014^TM product and what is a product with a degree of compatibility to an RC2014^TM
• To reduce the chance of trademark infringement (RC2014 is a trademark belonging to RFC2795 Ltd)

The RC2014^TM bus specification is a subset of the full RCBus specification. This subset is defined by the RCBus-2014 specification. Similarly, the Z80 family extensions are defined by the RCBus-Z80 specification. Other processors and applications have their own extensions within the RCBus specification. Compatibility can be defined by which specifications are supported.
