Trying to track down this issue on an MPU-200 for Meteor and not sure of the next step:
MPU will boot and I get all 7 'flashes', but it is running slow. It takes about 35 seconds to get thru all 7 flashes, and the 'flashes' themselves last about 1 second each.
I checked the clock into the 6800. Both phases are nice clean square waves, but at about 233kHz each (about 1/4 speed). It is jumpered for the higher clock rate.
I checked resistor values and continuity in the clock circuit, and didn't see any issues.
At this point, I'm looking at U15 or U16 as being the culprit, or maybe the caps at C14 and C15? Is there any way to isolate which component? Those are all part of a feedback loop, so it's hard to isolate without breaking the feedback (i.e. taking something out of the circuit).
TIA
