unixdude Posted August 7, 2021 Share Posted August 7, 2021 Hey, all. I'm modding a 5200 for UAV today, and I came across a couple of oddities. Anybody know what these are? On the GTIA, pin 11 is pulled and is not connected to anything. On the bottom left of the board, there's a couple of wires, and one of the pins is pulled on a 74LS51. As you can see from the pic, this 5200 works fine. Thanks. Quote Link to comment Share on other sites More sharing options...
+x=usr(1536) Posted August 7, 2021 Share Posted August 7, 2021 This looks to be the factory compatibility modification for the 2-port 5200. Check the 5200 FAQ, Section 4.10, and see if the three items listed therein apply. It appears as though at least two of them do in your case Quote Link to comment Share on other sites More sharing options...
+-^CrossBow^- Posted August 7, 2021 Share Posted August 7, 2021 Like @x=usr(1536) stated, these are factory done from back in the day. Nothing to worry about. Quote Link to comment Share on other sites More sharing options...
unixdude Posted August 7, 2021 Author Share Posted August 7, 2021 Thanks, I didn't figure it was something to worry about, just wondered what it was. And, of course the S-video output looks amazing -- thanks @-^CrossBow^- for encouraging me to not stop at composite. And, @x=usr(1536), thanks for the link to the FAQ! 1 Quote Link to comment Share on other sites More sharing options...
