But the parallel backplanes are gone and replaced by serial links, such as Ethernet or USB. A lot of industrial computers used the ISA bus, which was 8 MBps, or VME bus which originally was 40 MBps. This is easily matched and exceeded by common Ethernet links today! and so much easier to put things together using simple cabling vs limited capacity backplane boxes. ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
