WhataKowinkydink Posted April 20, 2022 Share Posted April 20, 2022 Interesting find and bit of history. Also rather sad to see the state that it is in. Quote Link to comment Share on other sites More sharing options...
+dhe Posted April 21, 2022 Author Share Posted April 21, 2022 And @FALCOR4 posted a picture of his unit. Pretty much answers, what it would be like, if TI created a 16bit, 99/4a. Easy enough to debug... First unplug the daughter board, test it in another console, and plug a 9900 in the suspect console. With luck, we know what component is bad. Dealing with piggy backed chips is hard. Notice the tops board is all socketed also for easy of testing - except for the 9900 I think a TL866 could do the remainder of the chips. 4 Quote Link to comment Share on other sites More sharing options...
