Some of my designs are available as kits at Tindie. These include Z80 computer kits, Z180 computer kits, and modules for RC2014 and Z50Bus. Unless otherwise stated, everything is included, except tools, solder, batteries, and cleaning materials.
Some components, spares, and accessories are available here, including programmed ROMs.

Kits designed for BP80 bus
Backplane 80 (BP80) is an RC2014 bus extended to 80-pins, with pins 40 and 80 forming a Z80 mode 2 interrupt daisy chain. Official RC2014 modules work with BP80 backplanes, but BP80 modules do not work with RC2014 backplanes as they require the extra pins.
