Is there any technical documentation on the MPU4 system used in many fruit machines? It may sound a bit odd, but I want to have a go at writing my own code to run on a fruit machine I recently acquired, so information on any encryption used, processor, memory mapped registers etc. would be much appreciated if anybody knows where I can find it.

Thanks

Hey Orkie - welcome

Have you taken a look at the manual - there will be some info in there. Links posted below.

MPU4 Technical manual - The MPU Mecca

MPU4 Circuit diagrams - The MPU Mecca

You may well find the info you require over at The Mecca - The MPU Mecca

good luck
