New #RC2014 boards that arrived today work exactly as planned. That's a huge relief having changed a lot since the last revision.

Spent a lot of time on the firmware today. Happy to report that it is making progress... bars

Thankfully, with the upcoming #BlackFriday sale for #RC2014 kits, I am not expecting anybody to buy anything from #z80Kits in the next couple of days, so I should be able to crack on with the development of this.
