What is RC2014?

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.

As a bare minimum, you will need a CPU, ROM, RAM, Clock and Input/Output module. The RC2014 is designed in such a way that you can build your own modules to expand it. As such, if you have access to similar components, or have specific needs, you might not need all the items I have on offer.

What is this module?

This module allows you to add an IDE hard disk to your RC2014. It is based around the Intel 8255 Programmable Peripheral Interface (PPI) chip and is supported using RomWBW. An RC2014 82c55 disk IO driver has also been added to z88dk, enabling disk access from your C programs. ChaN's FatFS has been adapted to run on top of this enabling FAT filesystem access https://github.com/feilipu/z88dk-libraries/tree/master/ff. Note that there is no support to load or save files from a standard RC2014 running BASIC

Both connectors are included to allow a standard 3.5" or laptop style 2.5" drive to be used. If a 2.5" drive is used, it can be powered from the RC2014 power bus, or from an external 5v supply via the barrel jack.

Where have I seen this before?

This product is a simplified version of Ed Brindleys IDE Adapter, but using a DIP-40 chip and standard RC2014 address circuitry. The jumpers and switches have been removed to allow for an easier setup, but otherwise it operates the same. No changes will need to be made to RomWBW to use this.

What do I get?

• Standard Kit This includes all the components to build the 8255 IDE Module, including PCB, all chips, headers and passive components.

• PCB Only Go on, take a guess what this kit includes ;-)
