====== ECB Bus Extender ======

{{https://retrobrewcomputers.org/lib/exe/fetch.php?media=boards:ecb:bus-extender:photos:busextender-front.jpg}}

===== Introduction =====

The ECB Bus Extender card extends the ECB bus upwards so that a card can be more easily debugged with access to both sides above the card cage/enclosure. Connection points are also provided where bus signals can be probed or disconnected if desired.

This board was designed by Michael Haardt who made many early contributions to the original projects which later became the RBC wiki. His original site for the board can be found [[http://www.moria.de/~michael/comp/ecb/busextender/|here]]
