I was using software 4.1, upgraded to 4.2, then downgraded to 3.0. All versions instantly failed when programming this device. I opened up the devices.txt from version 3.0, and noticed that HN27c4000 is set to RVpp="5v". After looking at the datasheet, these chips need 12v to program. I added the following paramaters and the device now burns perfectly, every time: Name="HN27C4000",ID="XXXX",Class="27C800",Category="EPROM",MFG="HITACHI",CodeSize="524288",WVCC="6.5V",WVPP="12V",Adapter="16 BIT EPROM Adapter DIP42",RVpp="5V",Message="Put chip in 42 pin socket and bottom aligned with the socket.";//by EZo - fixed by billd420 Hope that helps someone else! -Bill [/quote]    Insert an Image File Check here to include your profile signature.
