Not to forget ATARI - Yes, ATARI also used VME - the TT (you know,
the always anounced, never available and to expensive 68030 system)
had two ( 3 ?) VME slots for add ons. The idea was baicly to have a
chance to add 'better' Graphic cards, since the TT was intended as
Graphic Workstation.
Eventualy the TT was also in a somewhat unintentional demand from
engeneering companies (the TT would had given a beautifull low
cost VME development system) - again a market where ATARI did
totaly miss, while the customers where _WAITING_ for the machine.

Somewhat popular ? VME is still #1 when it comes to industrial apps.
Only the enhanced usage of PCs can stand against with ISA/PCI backplanes
and the _very_ popular PC104 systems.
