more but only if the volume was enough to be worth while. The right color
is machine specific. If you hold them near each other all my machines
have different color handles. I don't know if it is aging or poor control
of plastic batches.

Magnetic tape drives are *physically* sequential-access, of course, but the
TU56 (for example) is logically a random-access, block-oriented device. (with
highly variable latency ;))
