Backplane-8

The RC2014 was designed such that standard stripboard could be used as the backplane. This board essentially does the same as stripboard, but has been designed specifically for the RC2014 and has a few extra features features

Backplane8

  • Expandable up to 8 daughter-boards – Although the standard RC2014 only requires 5 slots, this gives you the option to use up to 8 boards in total
  • DC power socket – 2.1/5.5mm barrel jack. If you wish to power the RC2014 with 6v – 14v, there are pads for mounting a LM7805 regulator and capacitors to give a regulated 5v to the board. If you are using a regulated 5v supply, such as from a USB adapter,simply short the two pads shown within the LM7805 footprint
  • Isolating pads on data and address lines – Many Z80 designs have resistors placed between the CPU and some peripherals. This backplane gives you the flexibility of totally isolating any of the address or data lines, adding resistors or simply soldering links or jumpers across. Slots 1 & 2, slots 3, 4, 5 & 6 and slots 7 & 8 can all be partitioned off if required.
  • 40 pin sockets – RC2014 modules typically uses 34 or 36 pins, but additional sockets are available for extended features.
  • Clearly labelled pin identifiers.
  • Nice rounded corners and mounting holes
  • Power LED
  • Reset button

For a minimal RC2014 I recommend using slots 2,3,4,5 & 6 with the clock in module 2.  That way you do not have to solder links across any of the address or data lines
