Here ‘re the solution helps you erase 35080vp with a R270 programmer reworked. The risk is yours. Good luck!
1- Change the power supply to good quality: 12V 1.5A !
2- Change capacitor :
3- Change resistor:
And to make R270 better on M35080, please replace the resistor R11 by 200-1K resistor.
Tested with M35080vp: success!
Again, you will try all at your own risk!!!!!!!
