I just got the TOP 2005 Programmer. The install with the included software is garbage...downloaded the new code from this site. All seems to be working - thanks for being here !!
I am sure I am not doing something right and I will apologise up front for being a total noob at this.
So far I believe I have managed to successfully read a EPROM that I want to duplicate. It is a 27C256 Eprom. I saved the file to my hard drive.
1st question: My chip has a sticker on it that reads Checksum CB15. Where in this software am I supposed to see this ?
I am now dropping in a 27C512 in the burner. I know that I need to do an offset to make this larger chip suitable however I just tried to do a straight write and am getting errors when trying to burn it.
2nd question: What am I doing wrong to get these errors ???
I tried a basic read on a blank 27c512 - got back all FC FF's then I did a write of an empty file and it burnt nicely.
I load up the aforementioned file - and try and burn that (on another new chip)- same errors.
