/* PCW Expansion Port adapter Video Circuit Q1 (transistor) */
As a result of this investigation, the BOM was updated to specify a '''74F02''' for U2.
=== PCW and 6128 Expansion Port adapter Video Circuit Q1 (transistor) 50 way edge connector ===Q1 of I made a mistake with the PCW Expansion Port row spacing on the boards so it will be necessary to bend the two pin rows inwards so they nearly touch, then bend them out about 1/2 way down each leg with needle nose pliers. Really sorry about that. But it's reasonably easy to do if you're careful. I posted this picture on the forum, and I hope it illustrates the point. http://www.cpcwiki.eu/forum/amstrad-cpc-hardware/cpc-ide-adapter video circuit -anyone/?action=dlattach;attach=21948;image The rows are 2.54mm apart, which is specified as fine if you want to fit a BC237 NPN small signal transistor50 way box header and use a 50 way IDC connector to 50 way IDC edge connector cable, but not fine for fitting this type of edge connector. HoweverHence a little bit of hackery being necessary when fitting the edge connector directly. Also, I discovered please note that the BC549 used on the uIDE-8 board can also edge connector must be used in fitted so that it comes out of the video circuit'''back''' of the board. You may find other equivalent transistors will do Please check the job herepictures of the finished boards and ensure you get this right. If in doubt, toocontact me.
