Good grief! All this discussion--about what amounts to a straightforward task.
Get a PC with a 1.2M 5.25" drive and some DD floppies. Make sure it boots to MS-DOS, not Windows. Grab a copy of Dave Dunfield's ImageDisk. (on the classiccmp server, if memory serves). Use it read and make images of your source disks. Then use it to write as many copy as you want from the images. ImageDisk does a "read ID" on each track to get the exact sector ordering and skew. Easy peasy--hardly worth more than one or two posts. (And yes, I've used it to copy RX50 floppies for a customer and they were very happy with the result. I think it was for an Air Force teaching setup using VAXen. One advantage was that I could tell them just to drop me an email if they needed more, as I had the images.) --Chuck
