RC2014 is a simple 8 bit Z80 based modular computer. It is inspired by the home built computers of the late 70s and computer revolution of the early 80s. It is not a clone of anything specific, but there are suggestions of the ZX81, UK101, S100, Superboard II and Apple I in here. It nominally has 8K ROM, 32K RAM, runs at 7.3728MHz and communicates over serial at 115,200 baud.
The original RC2014 was designed such that standard stripboard could be used as the backplane with all the essential signals fitting within a 36 pin bus. The Backplane 8, with 8 slots of 40 pins is ideal for this.
For more advanced uses, however, a 40 pin bus is insufficient and 8 slots can be limiting. For a while, new modules such as the SD Memory Dump Module, 64K RAM Module and the Pageable ROM Module have been designed with the Enhanced Bus in mind. Whilst these modules can easily be connected on the standard Backplane 8 or Backplane 5 with jumper cables for the additional signals, this backplane gives a neater, more professional solution.
If you are using regular modules, and you haven't run out of slots on your Backplane 8 then, probably, you don't need to upgrade. However, this does open the door to a much more advanced RC2014, if that's what you're looking for. Features include;
