for anyone wanting to try David's MFM emulator in an HP MFM 7945 disk box, here is the
format, determined from reading a Vertex V170 drive from one

--sectors 32,0 --heads 7 --cylinders 987 --header_crc 0xffff,0x1021,16,0 --data_crc  0xffffffff,0x140a0445,32,5 --format
WD_1006 --sector_length 256

The 7945 is notoriously flaky because of the Vertex drives.
