Always hangs if I try to write pass adress B0 If I only write within that area it works fine. Made a new device line inside devices.txt but i cannot alter the WVPP to other values because the software then complains when I start it. my own made device: Name="TMS87C257",ID="97C2",Class="87C257",Category="EPROM",MFG="TI",RVPP="5V",WVPP="12v",WVCC="5v"; Datasheet here: h**p://dl.dropbox.com/u/15772069/TMS87C257.pdf [/quote]    Insert an Image File Check here to include your profile signature.
