The standard came from the Eurocard format for industrial control systems.
The 68000 card connection came form the VME bus, which was a double height
euro system. Many other comapnies used the format, quite a bit of Inmos
Transputer stuff went into VME type systems, I once saw a 64 transputer mini
supercomputer built in a 19" VME case.

There was also the ill fated 'Futurebus', whcih arrived too late, though
would have been just about the ultimate card based computer standard for
it's time.
