Please help with Battlezone board

Watchdog is resetting in play mode. In test mode, I get 2 low beeps (2114's
at H2 and J2 are testing good), then I get 2 high beeps (A1 and A2 are
testing bad).
I've socketed and replaced A1 and A2 with tested good 2114's. I've also
socketed and replaced the LS245's at P2 and F2. I socketed replaced the
LS244's at K3 and N2 with new AS244's. The 6502A is tested good in another
board. Address lines from the CPU all show activity as they should.
I'm pretty stuck on this one, please help if you can.

Thanks Very Much,
Michael Kelley
