+PIOMON is a program to verify operation of the Z80 MBC DUALPIO board
+
+Most testing requires the use of loopback hardware constructed as:
+
+Channel A   RDY STB  D0  D1  D2  D3  D4  D5  D6  D7
+             \   /   |   |   |   |   |   |   |   |
+              \ /    |   |   |   |   |   |   |   |
+               X     |   |   |   |   |   |   |   |
+              / \    |   |   |   |   |   |   |   |
+             /   \   |   |   |   |   |   |   |   |
+Channel B   RDY STB  D0  D1  D2  D3  D4  D5  D6  D7
+
+The DUALPIO has, well, 2 PIO chips.  Only one chip
+is tested at a time.  At startup, PIOMON will ask
+you for the port of the chip to test.  It defaults
+to the standard port number for the primary PIO chip
+on an MBC DUALPIO board.
+
+The port number specified is the base I/O port.  Each
+chip has two channels which are addressed in the
+menu by specifying A or B.
+
+MBC DUALPIO Primary PIO = 0xB8
+MBC DUALPIO Secondary PIO = 0xBC
+
+If you try to use PIOMON without the RDY and STB
+cross connected, you may have interrupt issues
+because STB will be floating.
+
+N.B., V1 and V2 of the DUALPIO lack a hardware reset.  The
+PIO chips will reset at power-on, but they do not reset
+when the reset button is pushed.
+
+Happy St. Patrick's Day!!!
