This PCB is designed as an aid to prototyping Z50Bus cards on solderless breadboards. It allows Z50Bus signals to be easily connected to a breadboard with Dupont cables. The board includes flexible I/O address decoding, so you don't need to include such circuitry on every prototype. The decoding has jumpers to configure the start address and range. This includes allowing partial decoding with shadow addresses. The address decoding circuit provides an I/O enable signal (/IOEN) and also separate read and write versions (/IORD and /IOWR). This range of enable signals allows easy interfacing to most I/O devices. **Features** - Easy access to Z50Bus signals - Flexible address decoding generates /IOWR, /IORD and /IOEN - Connection to solderless breadboards with Dupont cables **Documentation** This product has a user guide (PDF), which includes component sourcing and assembly instructions.
