Looking across the main distributors of Scalextric products it appears that stock of the C7042 Advanced Power Base (APB) has run low.
Also, we now know that when throttle ports fail this can also lead to wider reliability issues with the APB - so it is often not as simple as avoiding using the dead ports.
This brings consideration of whether the microcontroller can be removed and replaced, back into scope.
Over the next few posts I will share a step-by-step guide covering the removal and replacement of the microcontroller.
This is not something that everyone can try. However there are likely to be a few members across the digital slot car community who will have the skills and equipment to successfully carry out the procedures involved.
What will follow is a high-level outline guide.
I hope this thread generates some interest and proves useful too.
