Hi, A couple of people requested the Option Board Software. I created image files of the original floppies and uploaded them to http://www.btinternet.com/~mark_k/Option_Board_v5.4_3.5.bin.gz http://www.btinternet.com/~mark_k/Option_Board_v5.4_5.25.bin.gz After downloading decompress using gzip, then use your favourite disk-image- writing program to write to a (formatted) floppy disk. -- Mark
