Hi moto
I have one of my 1200s mounting a volume with ProNET through a parallel cable to my other 1200. They both use the same Jaz disk as DH0: at the same time. This sounds pretty similar to what you are aiming for. ProNet is small enough to fit on a floppy if it is a little slow but the cable was easy enough to make and it beats having two hard drives of the same files. Just wish I had one of those 3.9 ROMs you have :-)
