5 1/4" hard-sectored disk..

From: "Jim Donoghue" <jim(a)smithy.com> I have some 5 1/4" hard-sectored disks that contain CPU microcode. They aren't 'formatted' with a filesystem, but are read with a simple board that contains some 9602's, a shift register, and a Z80. A dilemma: should I try to intercept the data from the board, write it to flash memory, and build a board to replace the whole Z80/hard-sectored disk thing, *or* try to build something to write the data stream out to another 5 1/4" disk. The Z80 doesn't care about the sector pulses - only the index pulse. So I could get away with a standard floppy instead of a hard-sectored one. The disk thing would allow me to keep using the original hardware, which would be nice, but I don't know the first thing about attempting to write the data stream back to the disk. I have no backups of the microcode disk, and no way to replace it when it dies. Every time I fire the thing up I feel I'm getting a little closer to it's death... Jim
