1. Solution for R270 BDM Programmer erase M35080 issue

I have a R270 BDM programmer R270+, my problem is that it reads the 35080vp chip but it can not erase it, it gives me error.  I ask because all of bought read 35080 and cas but not erase 35080. How to solve the problem?

Customer Solutions:

Sometimes vp don’t erase just replace the chip

Solution 1)

I played a few hours with my R270 programmer, and I succeed to make it erase 35080V6/VP in a few minutes.
First I changed 7805 with L7805CV, before voltage was 4.94V, after that is 5.02V, but nothing happens, still can’t erase more than hour.
after that I start to play with 35080 PCB, and in the end started to erase 35080V6/VP after 74HC125 changed with 74HCT125M, erase 5-10min tryed on 3 chips, maybe if I change 74HC00 will be better, but I haven’t one for try.
