====== The following information described details of previous versions ======

===== Version 1 =====

In version 1 the Zilog peripheral board header layouts are different to the other boards in the ECB and are shown below. Custom cables must be made. For example - the Z80-DART/SIO doesn't provide a DSR input so it uses DCD instead. Ring Indicator is also not used.

Version 2 aligns the board with standard IBM PC standard.
