Hi Lindy, Don't know if this will help, but I recall using a product about 10, maybe 15 years ago on our VM systems called: VM Magic , from a company called SDI ( looks like SDISW now ). It allowed the user to emulate any DASD device on any real DASD device. In our case we needed to run a DOS/VS R34 system that would only support 3330 DASD devices. The VM Magic product allowed us to emulate mini-disk 3330's on our real 3380 DASD devices ( later even 3390's ). I remember we had to 're-build' the VM/CP nucleus to install the hooks that the VM Magic product needed. We had to add, maybe replace, don't remember, a couple of entires in the VM/CP nucleus 'CNTL' file before the VM/CP nucleus re-build. When I saw your post, I thought of this VM Magic product and how it did its 'magic'.
