I have a problems with my top853(have uv eraser)all brand new. I can read 2732 and 27512 but i cant burn them. With the new software it sas ex:20000:error! (file=ad,chip=ff) Wath am i doing wrong. And v2.52 dont showe checksum like v1.43.
Check the Vpp pin during the programming, to see if the 12V Vpp is correct.
I am newbe to this???? Did som testing today. On the amd 27c512 it sas 4000 error file:f1 chip:ff ,i have erased it for 30 min. On the ??? 2732 it sas oooo error file:49 chip ff ,erased it 30 min Its the start adress for eproms but the eprom is blank if i check it on the top 853 Looks like it cant be erased or wath. Its for my car,now i have driving with emulator to get it right but want a eprom.
