I'm going to be using a 3' all pins straight through DB25 serial cable between the Altair 8800C I built and a couple of floppy drives I'm going to build an enclosure for.
There are 14 signals I plan to have are ds1, ds2, ds3, ds4, motor, index, direction, step, write data, write gate, track 0, write protect, read data and side, which leaves 11 grounds out of the DB25.
My question is, of all the floppy drives using DB25, is there any sort of standard for which pins are which?
