Don't understand that Ronnie? If the 100Hz is going in it should come out as a nice 100Hz square wave about 5v p2p assuming the chip is powered ok. Pin 12 feeds IC2 (6840) and IC3 (6821) but I can't believe they would be causing anything.

Hi chaps, and chapesses. As I get MPU3's in various states of damage one of the most usual things is the cart holder is either missing or broken. As everyone knows without the holder intermittent faults abound due to vibration. Trying to find spare carts is more or less impossible so I thought I'd have a go at knocking up a 3D version. Here's the 2nd attempt, the 1st one the mounting holes spacing were about a 1mm out. I can probably use it but wanted a good one straight off the printer. Having said that it does need a little filing to ease the connector in but everything lines up which is the main objective. I will install it this afternoon and report back but so far all looks good. The rough bits on the bottom are where the supports have to go to enable the raised bit which takes the metal brackets. I cut those off with a small chisel. If there's any interest I'll post the STL file so you can print your own or if you want to improve it. All I ask is you post it back here so I can use it as well.
