__Cipher boards:__
There are two of these:

I suspect they're from some form of terminal (or maybe printer?), and
now that they're separated from the rest of the system they're just
junk. Note that someone seems to have scavenged a bunch of power
transistors (or something) from them.
Here is a Youtube video of someone loading tape on an 990 cache
streamer. It is a much upgraded, and probably SCSI interface version of
the streamer, but the loading is very similar. The electronics are
pretty much completely different.
The above board by the way has P1/P2 formatted Pertec tape interface
connectors in and out on the left end of the board you photographed.
The Cipher SCSI usually have 50 pin scsi single ended interfaces. There
is a box that attaches to the rear of the Microdata drive in the
previous ebay link which converts the SCSI interface in to a formatted
P1/P2 Pertec interface.
