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.

Standalone systems

These kits do not have external expansion buses.

Kits designed for Z50Bus

These kits are compliant with the Z50Bus specification.

Kits designed for RCBus

The RCBus is an extended RC2014 bus able to support a range of processors and advanced features.

Kits designed for RC2014 bus

These kits are compliant with the RC2014 specification. The modules listed here all work with BP80 backplanes (below).

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.
