If you’re into making I/O cards for the RC2014 than this enhanced prototype board will be of interest to you.

It features circuitry to for selectable decoding the I/O address and also gates to generate !IORD and !IOWR signals, as well as two spare OR gates.

It is larger than a normal RC2014 card but that is intentional so you have as much prototyping area as possible for building a circuit.

It features both the classic single 39-pin row pin-header for the original RC2014 pin-out and also a 39-pin double row pin-header for the newer enhanced RC2014 bus pin-out.

It is designed for DIL components and features central tracks for easy connecting 5V and ground power rails. Extra 5V and ground rails are available around its edges.

The IC’s used are:

• 74LS32 Quad OR gate
• 74LS688 Octal (8-bit) magnitude comparator

Available as a PCB only or as a PCB + connector kit
