evening all,a couple of years back I got a a500 with mark 21 controller. well the controller is now toast and I was lucky to get a mark 25 controller over the weekend.which I will need to melt across in the coming months.But like all things sodick..... power down means memory loss.I am seeking sys1 sys2 and sys3 disks please. or at least the images. I have a good set of manuals arrive with this controller including a set of machine parameters (happy to share and care)please could you let me know if you have the floppy image disk or does anyone know where I can download them from?many thanks G
