My arbitrary sequence counter won't function, help please!

[XPISigma]

Hello,

Been working on a circuit for class that counts up through 0,1,4,3,7,6. 

I made the excitation table, did the kmaps, and found what gates I needed to add. That left me with:

More info if it helps.

JC is C

KC is C' + B'

JB is A + C'

KB is C'

JA is B'

KA is A + B'

Thank you for your help! I'm at such a conundrum. The display only has a 7 on it, it won't even budge.

XPISigma,

I arrive at a slightly different set of equations, where JB = AC', JA = A' + B' and

KA = A'B' + AB

With these, I get a counter with the required sequence 0-1-4-3-7-6.

best,

Chris
