Today i try to read out the ROM images of the D8049C microcontrollers of several Korg Poly-61, as one of the 3 machines i have here has a broken UI controller. For now, i successfully read out a keyboard scanner, having some trouble with the other MCUs.
The basics you need to know on how to read out the ROM image on MCS-48 CPUs comes from here: http://www.sbprojects.com/projects/8049spy/8049spy.htm
I used to use 8048's 15 or 20 years ago
