# Volksboard 2 is planned to support separation of the two haves of the board,
# while using only 8 cross wires; to accomplish this, it is anticipated that
# a 3-to-8 decoder would be used to drive the columns. That means a budget
# of 3 cross wires for the columns; 2 for power and ground; leaving only 3 for
# the rows. Thus, the decision to use 7 columns (vs 6 on the Volksboard)
# and 3 rows on each side (vs 7 total on the Volksboard - 3 per side plus one for vowels
# that appears on both sides); and also the decision to wire it
# so that the columns are driven and the rows are sensed -- so the diodes
# are reversed in polarity from the Volksboard.
