Greetings!
I wanted to add a serial port to my 1981 Gorf arcade machine. Since it is
really just a specialized Z80 computer, I was just going to tap the signals
from the Z80 pins and create a small sub-board with a UART. I haven't really
got this working yet and was since I have virtually zero experience with any
hardware design, thought I might beg a question or two.
First, you can see the schematic and other info here:
