I had no idea people were making OMNIBUS boards in 1995. That's amazing.
There are still machines in commercial use, but most of them are so deep
inside something else that nobody knows how to upgrade them, let alone
_want_ to change out the old for the new.
I see they are a British company (
http://www.tellima.co.uk) I guess that
means that their products will be a wee bit less common on this side of
the pond.
