The [[ECB Bus]] is a standarized bus for Z80 and 8080 computers, ; similar to the ISA bus used on 80x86 computers. In theory, ECB cards could be used with different computers - however, in practice, different computer systems have different memory and I/O maps, so one would need to modify the memory and I/O or memory address decoding (on the ECB cards) in order to get them working on other computers.

== History == The ECB bus was invented in 1977 by the german company Kontron. '''ECB''' originally stands for "Einfach Europaformat Computer Baugruppen" (Simple Europaformat Computer Modules; where "Europaformat" refers to a standarized circuit board size of 160x100mm). ECB is sometimes also referred to as "Europa Bus" or "Europe Card Bus".  The ECB bus was invented in 1977 by the german company Kontron. And, it's is still used in some situations (for example, as by 2010, www.reichelt.de still sells 96-pin "Euro Bus" mother backplane boards). Confusingly, Kontron themselves are now using the abbreviation "ECB" for PCI-bus based "Embedded Computer Boards", which have little (or nothing) to do with the original ECB bus.
