Kits

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.

• SC131 – Pocket-sized Z180 RomWBW CP/M computer

Kits designed for RC2014 bus

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

• Backplanes: (40-pin)
  • SC133 – Modular Backplane
  • SC141 – Modular Backplane
• Modules: (RC2014 standard profile)
  • SC102 – Z80 CTC Module
  • SC103 – Z80 PIO Module
  • SC104 – Z80 SIO/2 Module
  • SC108 – Z80 Processor Module
  • SC110 – Z80 Serial with Timer Module
  • SC129 – Digital I/O Module
  • SC132 – Z80 SIO/0 Module
• Modules: (RC2014 low profile)
  • SC134 – LED Output Module
  • SC135 – Digital Output Module
  • SC136 – Digital Input Module
  • SC137 – I2C Bus Master Module
  • SC142 – Power Supply Module
• Motherboards and SBCs:
  • SC114 – Z80 SBC/Motherboard
  • SC130 – Z180 SBC/Motherboard

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.

• Backplanes:
  • SC112 – Modular Backplane
  • SC113 – Modular Backplane
  • SC116 – 3-slot Backplane
• Modules:
  • SC111 – Z180 CPU Module
  • SC119 – Z180 Memory Module
• Motherboards and SBCs:
  • SC126 – Z180 SBC/Motherboard

Kits designed for Z50Bus

These kits are compliant with the Z50Bus specification.

• SC118 – Z80 Processor Card
• SC125 – Serial and Timer Card
• SC127 – Compact Flash Interface Card
• SC128 – Modular Backplane
• SC140 – Z180 Processor Card

I2C Bus

• SC138 – I2C Memory Card
• SC400 – I2C Bus Modules
  • SC401 – I2C Prototyping Module
  • SC402 – I2C Memory Module (24xxxx)
  • SC403 – I2C 16-bit Digital I/O Module (MCP23018) – soon
  • SC404 – I2C 8-bit Digital I/O Module (MCP23008) – soon
