Or with the 3480 autoloaders, "Hey look, it automatically loaded the next tape!" Ooh, ahh! Don't get me wrong, they were a cool technology upgrade but pretty unimpressive to watch them in action compared to seeing the 3420s start/stop and hearing the flapping sound when a tape rewound off the takeup spool.

I remember the bunches of cables involved with the 3420s+3803, but I did not remember the exact arrangement. As we have said, it was a long time ago. (And yes, the 3490-type tape cartridges are as handy — except it was seldom that there were as many of these just lying around waiting to be used. Of course, that depended on the type of installation involved, etc, etc.) With 3480s one could make an interesting "show" for visiting executives. Remember the oscillating sort?
