Camerica CME-01: 0.6" 28-pin PDIP (Mapper 71 or Mapper 232 depending on PCB)

                                     .---v---.
(R)  $C000.2 OR CPU-A14 (PRG A16) <- |01   28| -- VCC
(R)  $C000.1 OR CPU-A14 (PRG A15) <- |02   27| -> $C000.3 OR CPU-A14 (PRG A17) (R)
                   (R,N)  CPU-A12 -> |03   26| -> $C000.0 OR CPU-A14 (PRG A14) (R)
                     (N)  CPU-A14 -> |04   25| <- CPU A13 (R,N)
                     (N) CPU /RMS -> |05   24| -> PRG /CE (R)
                     (N)  CIC+RST -> |06   23| -> PRG /OE (R)
                     (N)  CPU R/W -> |07   22| <> CPU D7  (R,N)
                   (n/c)  $8000.4 <- |08   21| <> CPU D0  (R,N)
                   (n/c)  $8000.2 <- |09   20| <> CPU D6  (R,N)
                   (n/c)  $8000.3 <- |10   19| <> CPU D1  (R,N)
                           MOSFET <- |11   18| <> CPU D5  (R,N)
                     10MHz CLK IN -> |12   17| <> CPU D2  (R,N)
                    10MHz CLK OUT <- |13   16| <> CPU D4  (R,N)
                              GND -- |14   15| <> CPU D3  (R,N)
                                     '-------'

The data bus injects a NOP slide for a fixed amount of time, relying on using the MOSFET connected to the MOSFET output to brown out the NES's power supply and crash the CIC.
