CF Card PPIDE for RC2014 public

This module is intended to combine the reliability of the parallel port IDE module (https://z80kits.com/shop/rc2014-ide-hard-drive-module/) with the convenience of a Compact Flash socket.  

There are some useful notes about the CF socket and the PCB footprint for it here: https://github.com/PickledDog/rc-cfcard

It's worth noting the pin spacing on the CF socket is very tight. This makes it a very hard part to solder. I don't recommend trying unless you're experienced at soldering and you have the right tools (fine tip soldering iron, solder wick to fix any bridges, etc).

The remaining parts are pretty common. Stephen C Cousins has very helpfully documented many of them here: https://smallcomputercentral.wordpress.com/components/
