The Family Basic Keyboard (HVC-007) was a peripheral released with the Family Basic package in 1984. With the data recorder that could be attached to it, it allowed the Famicom to have the abilities of the average home computer of around that time. It is a generic 72 button keyboard using common matrix logic, and can be connected to the Famicom at the expansion port.

||+-- Reset the keyboard to the first row.
|+--- Select column, row is incremented if this bit goes from high to low.
+---- Enable keyboard matrix (if 0, all voltages inside the keyboard will be 5V, reading back as logical 0 always)
Incrementing the row from the (keyless) 10th row will cause it to wrap back to the first row.
Output ($4017 read)
7 bit 0 ---- ---- xxxK KKKx | ||| +-+++--- Receive key status of currently selected row/column.
Any key that is held down, will read back as 0.
($4016 reads from the data recorder.)
