You'd be better with an AUI-to-10baseT adapter.  And it would most 
likely be a switch rather than a hub.

IIRC you need to set some links on an Acorn AKA25 to use the AUI 
connector instead of the 10base2 coax connector.  The adaptors are very 
standard, and any AUI-to-10bT should work fine.  If Rob can't find one, 
I probably can.  We chucked loads of them, but I should still have a 
couple somewhere.
