We are offering service for coffee vending machines and some of our customers are offering old and outdated machines.
The problem we are facing is that we can replace the 68HC912D60C MCU but we can't write its memory contents. We tried to contact the manufacturer but they are no longer in business.
We want to read the MCU memory contents from a good MCU and transfer its contents to a "blank" MCU. On the motherboard there is a 6pin connector available for programming.
Is there a way to do this? Are there any programmers available that can allow us to do this ? Also, what IDE can we use to read the memory contents ?
