<p>A very useful board</p> <p><b>New page</b></p><div>[[Image:UA11UnibusAnalyzer.jpg|250px|thumb|right|UA11 Unibus Analyzer]]<br /> <br /> The '''UA11 Unibus Analyzer''' is not a [[Digital Equipment Corporation|DEC]] board, but something created by a member of the vintage computer community to help with debugging [[UNIBUS]] problems.<br /> <br /> It is a [[DEC card form factor|quad]] format card, which plus into any [[Small Peripheral Controller|SPC]] slot in a UNIBUS [[backplane]]; a set of [[Light Emitting Diode|LEDs]] show the status of all the UNIBUS lines. In addition, there are comparators which match [[data bus]] and [[address bus]] data to values in [[Dual Inline Package|DIP]] switch blocks, to provide a trigger for test gear; also, all UNIBUS signals are brought up un header pins for convenient access. <br /> <br /> It is available as a bare [[printed circuit board|PCB]], or a complete parts kit, which the user assembles themselves, or (for somewhat more) as a pre-assembled unit.<br /> <br /> ==External links==<br /> <br /> * [https://shiresoft.com/products/ua11/Unibus%20Analyzer.html Unibus Analyzer]<br /> ** [http://www.shiresoft.com/docs/ua11/UA11%20Parts%20List.html UA11 Parts List]<br /> <br /> [[Category: UNIBUS]]</div>
