reZet80 to RC2014 bus adapter

The adapter provides a simple one-to-one mapping of the bus signals.

Well, with the exception of BUSACK, BUSREQ, HALT, NMI, RFSH and WAIT that are only available on the extended RC2014 bus. Together with INT these signals are available but optional (can be user-defined signals) on the reZet80 CPU bus.
The RC2014 signals RX and TX are not available on the reZet80 CPU bus.
The signals USER1, USER2, USER3 and USER4 correspond to the user-defined but optional reZet80 signals.

This adapter can accomodate one reZet80 card or one RC2014 card and can further be connected to a reZet80 or an RC2014 backplane.
