Just rename the ".obj" files to ".hex". I don't know whether the TDE assembler embeds configuration info in the .obj files. If it does, you may have to clean up the file by deleting the line or two that contains the configuration... If those lines exist, they'll probably be at the end of the file; you'll recognize them by their out-of-range addresses. -Andy === Andrew Warren - fastfwd@ix.netcom.com === Fast Forward Engineering, Vista, California === http://www.geocities.com/SiliconValley/2499
