Z80 SIO2 Dual-UART Card for RC2014 bus (with clock)

Following on from last months Z80 CPU module for the RC2014 bus, here is a dual-serial SIO UART board.

So what makes it special?

It will work with either the standard RC2014 bus or the latest enhanced bus where all the Z80 CPU signals are available.

It includes several options for generating a Baud-Rate clock clock: Crystal, Oscillator or taken from RC2014 back plane.

The schematic is here:

and you can find it on Tindie here:
