Conceptually, it's not much different for Unibus. There's at least
one project out there that's working toward this but not yet available
If I was in a real hurry, I could take a quad prototype board and roll
my own. I happen to have a handful of DS8641s on hand from making
Unibus COMBOARDs 25 years ago. The quantity of discussion on this
list about modern Unibus transceiver replacements is rather large and
merely mentioning it is likely to cause a flare-up.
