With earlier 8's which you can manually load code into I have dump and restore programs you can use. On the VT78 their is no way I know of to get code into it without a special ROM on the back. Some older PC's controllers will work with 8" disks. I tried it so I could format but never got it working before I got a drive that could format itself. Don't know if its the PC or drive I was trying to use. PUTR looks like it should work http://www.dbit.com/pub/putr/. I have used it for RX50 disks but not 8". I think the images I have are compatible with it. This may also work but I am not familiar with it. http://www.dunfield.com/dave/dsktools.htm If this doesn't seem practical email me, I can make you a disk. Won't guarantee how prompt though.
