I have a related question. All of the S/260s that
I've seen had 2400

as well. Does anyone recall them being installed on a S/360 system?

Well, the early 2400 tape drives had a VERY simple
interface. The read amps delivered raw analog signals to
the controller. The write amps took 9 digital signals from
the controller. There were also forward, reverse, rewind,
write gate and EOT/BOT sensors, and unit select. VERY
simple interface at the VERY lowest possible level.
I can easily imagine the 729 series of drives may have had a
very similar interface. So, it may be possible that these
could be interchanged fairly easily.
