The X381 is an experimental 560-series timebase plug-in. It appears to have used a 3B1 plug-in as a starting point.
The front panel has a Nixie display which is driven by a Fairchild 9960 decoder/driver IC.
The X381 contains an enclosed backlit disk of film that is rotated by a front panel knob. The disk functions similarly to a quadrature optical encoder. but instead of generating two signals, it generates several signals.
