I've gotten an (really, another) RC2014 , and it's up and running. While I didn't design the hardware, it's nice to have a test platform for Z80 development. I'm using a Raspberry Pi as the serial terminal, which isn't so great (that's another project for another day), and it all works together nicely. I've got mine set up with the RomWBW and a Compact Flash card (that isn't working yet), so it should be a nice little dev platform.
 I have an RC2014 Pro, but it spews garbage on the console. All signs point to an issue with the serial board; while I have a replacement on order, I wanted something that works now.
