reZet80 HWDK - hardware development kit

This post describes the reZet80 HWDK (hardware development kit).
This is a pure hardware project.

The reZet80 HWDK provides all the parts needed to build your Z80-based hardware projects: 3 different power sockets, on/off switch, a simple reset switch, 2 bus slots and 1 expansion slot to further extend the system and a large wire-wrap area that can be used for your custom-designed circuits.
Additionally, 38 data, address and control bus pins are located alongside the board to easily attach logic analyzer and oscilloscope probes.
One of the bus slots has to be populated with a reZet80 CPU board R2.
Only a 5 Volt power supply has to be connected to one of the 3 power sockets/connectors.

Bill of materials:
- 1x reZet80 HWDK R0 PCB
- 2x 40-pin female sockets (CPU bus slots)
- 1x 40-pin right-angled female socket (CPU bus expansion slot)
- 1x 2-pin male connector (power supply)
- 1x 8-pin male connector (CPU data bus)
- 1x 14-pin male connector (CPU control bus)
- 1x 16-pin male connector (CPU address bus)
- 1x tactile push button switch (reset)
- 1x on/off/on switch
- 1x female DC power supply socket
- 1x 2-pin screw connector (power supply)
- 1x red LED
- 1x resistor (choose according to LED specs)
- 3x capacitor 100 nF
