CR10-A found in a MV4FS.

Serial-In-Line capacitor and resistor array used on NeoGeo boards, to protect input ports and auxiliary circuits (MV-LED). Also found as "CR10-A-*" on late NEO-CDD boards. Drop-in replacements seem hard to find but using common 1/4W resistors seems to be enough for a quick fix.

They are composed of 4 identical circuits. The leftmost pin's net pulls all outputs through 1k resistors. The 330 ohm resistors provide current protection (sometimes as fuses), the capacitors smooth out eventual spikes.
