+# Hex dump of tiny 8080 programs.
+
+Each program can be loaded into the simulator via the
+loadDataAsHexString() interface or the "LOAD DATA" input box.
+
+The HEX bytes in the strings are the binary sequence of 8080 machine
+instructions.
+
+## Simple adder
+
+Adds the two values stored at 0080H and 0081H, then writes the result
+to 0082H.

+```
+
+## Pattern shift
+
+Keep right shifting the value of register A.

+## I/O test
+
+Echos IN to OUT. Reads from SENSE SW. switches, then outputs the
+value.
