The card is made up off NAND gates connected in such a way as to create 8 outputs from three inputs.
I dont own this card but I solved it.
could someone try my solution:
| Spoiler (Rollover to View): |
i copied the circuit into a simulation program and tried every possible combination of inputs:
Input Output
000 01000101
001 01001100
010 01000101
011 01010000
100 01001000
101 01000001
110 01001110
111 01010100
The outputs spelt ELEPHANT in binary code
