what is the I/O on this? I don't see anything that looks like video out, or a serial port, so how to you interact with it?
(BTW awesome looking, I already have one ordered and am looking forward to playing around with CPM)
Thanks!

I/O on the Z80 Retro Badge is via the built in USB to serial chip. Just plugin in and it should show up as a com port. This is the main way of interacting with the badge.
There is also an expansion port. 40 pins that expose the address and memory buses, the necessary control lines, and even a couple of clock lines. This port opens up a lot of possibilities to expand the badge. You could theoretically create something like a video card and attach it.
