Z80.tar.bz2

The Z80 software running on the microcontroller. It will support execution of Z80 codes with a modified libZ80 library. The loadIntelHex function works with interrupts, but with a limited rate transfer. See PV on linux.
Download a hex file with:
pv -L 500 myhexfile.hex > /dev/ttyUSB0 (or USB1 depending on your setup)
