Hi Geoff, I am doing a workshop clearance for my Auntie of my Late Uncles items. I have some 5 1/4" floppies with pathtrace software on them. 3 in total. I have a pc with a 5" drive and I'm trying to find a serial mouse so I can access the disks. One of the disk covers has Fanuc written on it . Would these be of interest to you. I'm ex manual and cnc mechanical engineer. Regards Chris
