Boss OC-3 repair

[bandmbill]

I have picked up a broken Boss OC-3 pedal - anyone got a schematic?

The one you are looking for is not there but here are a bunch of other boss schematics for anyone that cares.

Looking at the PCB it appears to be a generic board - some components are not fitted - is the board shared between several pedals.

heres the oc-2 , i'd assume they are pretty similar...

[bandmbill]

Unfortunately not the same - the OC-3 has a couple of large multi-pin (one with 80 pins and one with 64) - most of the components are SMD.

can you post what the chips are? you'll probably need a magnifying glass or something...

The 64 pin is R03349278 B100C3 V1.00

80 pin R0256501 I think - there is a red line across it.
