1st board for NEDONAND project

This is a 1-bit slice of NEDONAND ALU supporting shift right RRC (000), shift left RLC (001), NAND (010), XOR (011) and ADD (1xx) operations. Pins description:

1) GND - ground;
2) O0 - bit 0 of ALU operation;
3) O1 - bit 1 of ALU operation;
4) O2 - bit 2 of ALU operation (if it's "1" then O0 and O1 are ignored);
5) A - input bit A (always from accumulator);
6) B - input bit B (might be from register or number);
7) C - input bit C (carry);
8) H - higher bit for rotation right;
9) L - lower bit for rotation left;
10) COUT - carry out;
11) DOUT - data out;
12) VCC - power +5V.
