I have in my gear museum a fairly large box with a couple of this type of 'hub
on a card' installed. And in this particular case, it made perfect sense, as
the box is an Evergreen Systems CAPserver, and has 16 486 single-board
computers tied to two 8-port hub cards (two ports on each modular plug, too),
with....wait for it... a 10Base-2 uplink. These were used mostly for remote
network access and remote desktop access.
If you want more data on this old and odd box, see
I can see a hub card being useful in an old NetWare server setting, though,
since if the server went down you might as well not have a network in the first
place, in that use case.
