This is the most capable and versatile of the Z80 retro computers I have built. It uses the Zilog Z180 CPU rather than the earlier Z80 version. It utilizes the same instruction set but is able to address 512 megabytes of ram and runs at a faster clock speed. This board also has two serial ports built in as well as two SPI ports and an I2C bus. This makes it easy to add readily available on board storage such as an SD card and Compact Flash. The main buss system is RC2014 compatible allowing for use RC2014 expansion cards. I am using the RC2014 CF expansion card and the RC2014 Digital I/O card with good success.
