+# RetroScreen
+C# to visualize a digital signal like MDA, CGA and EGA using an USB logic analyzer
+It is loosely based on the sigrok2EGA project and uses the hardware connections defined there (see at the end).
+
+If started without arguments, it tries to start sigrok in 24Mhz mode. Currently the sigrok location is hardcoded here:
+"C:\Program Files\sigrok\sigrok-cli\sigrok-cli"
+
+It can also be started in a CMD window with the "-" argument and accepts an 8 bit data stream as stdin. ("myprogramm | CGATest -").
