Method discovered in 1989, but only now published in English by Samir Ribic.
If this really works, maybe similar methods could work on fx-9850G, fx-7400G etc.

Hello,Machine code on an fx-8000G at Piotr Piatek's website:
http://www.pisi.com....dex.htm#fx8000g
Method discovered in 1989, but only now published in English by Samir Ribic.
If this really works, maybe similar methods could work on fx-9850G, fx-7400G etc.
I have found similar method (different way, but the same effect of unlocking RAM) on fx7700GB. see http://www.rkk.cz/~m...ls/FX7700GB.TXT
I never tried to write my own machine code, but I was able to run embedded diagnostic and transfer routines (Lx 387).
I don't know how is it with fx-7400 but on cfx9850G you can unlock the memory (http://www.rkk.cz/~m...ls/CFX9850G.TXT) but you cannot change stack because:
1. stack is in different segment
2. standard RAM is never executed
3. segment is never pushed on the stack, only offset
This applies for the early model of 9850G I have (1997), probably the later models with more functions may have some chance.
