Cluster Versions
There are dozens of different Clusters, some of which were manufactured by Motometer, and some by Bosch.
You can recognize the Bosch Cluster by its "grey" backplate, while the Motometer has a "black" backplate.
Bosch Cluster MCU
There are two main ICs used on the Bosch Cluster:
μPD70F3080 (Flash Memory)
μPD70F3081 (Mask Memory)
The μPD70F3081 cannot be reprogrammed by design as its using Masked ROM.
See https://en.wikipedia.org/wiki/Read-only_memory#Factory_programmed for details
The used MCU Subset is called V850/DB1 Avalon and is the first Generation of V850 MCUs.
Manual for the MCU can be found here:

Reprogramming
1. Buy a PG-FP4 Programmer. Important, not any other programmer(FP5,FP6)
2. Connect using following Diagrams:
3. Use Software for FP4 Programmer to read/write chip
Community Programmer
1. Solder following Components to the Board(see picture). R1 and R2 needs to be calculated 2. Connect to a UART2USB Bridge. Connect RTS and DTR Pins to RESET and Enable-Pin 3. Write Flasher somehow which should work
