As mentioned in my blog HERE, There is a new small batch of 4MB MMU RAM boards being produced.

During my testing I have seen that its probably not apparent that people are supposed to fit this board level and if they try and push it totally flushed, the right-hand side of the MMU adapter board (under the connector) having no pins, will push down further than the left-hand side causing a wonky insertion than can cause contact problems.

In order to address this problem I have designed a spacer which can simply be put on top of the MMU which will prevent the board from being inserted at an "unnatural angle".

These spacers will be included from the current batch onwards (August 2025).
