 * 1 -|A0       VDD|- 18
 * 2 -|A1      DOUT|- 17
 * 3 -|A2      OSC2|- 16
 * 4 -|A3      OSC1|- 15
 * 5 -|A4        TE|- 14
 * 6 -|A5        D0|- 13
 * 7 -|A6        D1|- 12
 * 8 -|A7        D2|- 11
 * 9 -|GND       D3|- 10

 *    Pin Assignment:
 *
 *	PIN0 = A5
 *	PIN1 = A6
 *	PIN2 = A7
 *
 *	PIN3 = D0
 *	PIN4 = D1
 *	PIN5 = D2
 *	PIN6 = D3
 *
 *	PIN7 = TE
 *
 * A0 - A4 are also very important. This source code
 * does not care about those pins. On the original PCB
 * you had to choose a code via dip switches. Now either you
 * put similiar dip switches on your new PCB (which I didn't)
 * or you just hardwire them to VCC or GND. But don't forget
 * to randomly pick a combination and use the same one on
 * all sockets!
