ApolloBoy Posted September 21, 2013 Share Posted September 21, 2013 are they a good upgrade to a two port 5200 system? I love 7800 s-video I bought from him. Definitely, I've added it to a few 5200s for others and I've been fairly impressed with the results, even through composite. Quote Link to comment Share on other sites More sharing options...
+grips03 Posted September 29, 2013 Share Posted September 29, 2013 (edited) very happy with the mod. thanks to low_budget and http://electronicsentimentalities.com Edited September 29, 2013 by grips03 Quote Link to comment Share on other sites More sharing options...
Master Phruby Posted October 4, 2013 Share Posted October 4, 2013 Thanks to LittleJoe and http://electronicsentimentalities.com my 5200 and 7800 now have s-video. He modified both of my units in a week and sent them back in better than new condition. The 7800 even has stereo. It was pretty cool playing Pac-man 4K and hearing the alarm in one speaker and the waka waka in the other. Both units video is crystal clear! So much better than the old RF. My 5200 also has a new case thanks to David (Boxpressed). Both units look fantastic now. My next project is to preform an AV mod on my Odyssey 2 and Colecovision.

How much is the 5200 s-video mod + install from Joe? for CV get the F18A VGA, its very good. Quote Link to comment Share on other sites More sharing options...
Master Phruby Posted October 5, 2013 Share Posted October 5, 2013 He charged $120 to mod both systems at the same time. (return shipping included) He suggested in order to cut down on shipping cost, to just send the 5200 motherboard and expansion panel for mounting. It's funny the return box was originally shipped to Joe from Al. Small world. Quote Link to comment Share on other sites More sharing options...
funknflow5200 Posted October 23, 2013 Share Posted October 23, 2013 Just did the s-video mod last night with the kit from electronicsentimentalities.com. Only took a few hours and the results are outstanding - the 5200 looks gorgeous on either my CRT or LCD displays. $30 insanely well spent... like others have said, I cannot believe how big that motherboard is for the 5200! they needed the massive case after all!

+grips03 Posted October 23, 2013 Share Posted October 23, 2013 Joe confirmed 4 port works fine as well. I'm going to order another one of these. Makes 5200 very nice. Quote Link to comment Share on other sites More sharing options...
funknflow5200 Posted October 24, 2013 Share Posted October 24, 2013 (edited) It is outrageously good. Playing defender never looked so sharp! Edited October 24, 2013 by funknflow5200 1 Quote Link to comment Share on other sites More sharing options...
+grips03 Posted October 31, 2013 Share Posted October 31, 2013 It is outrageously good. Playing defender never looked so sharp! I have two of these mods now, one for 4 port and one for 2 port. If I leave Moon Patrol on blue screen or if it switches to red / pinkish screen I can see faint blue vertical lines. Do you see these as well?

+grips03 Posted October 31, 2013 Share Posted October 31, 2013 Played on Tuesday night - didn't see that then// I'll hAve to look. with the s-video install, did you put the mod board on the pins of the video chip or did you run short wires? I ran short wires, say 2-3 inches to the mod board that's mounted on top of the 40 pin IC to the noth of the video chip. thanks Quote Link to comment Share on other sites More sharing options...
funknflow5200 Posted October 31, 2013 Share Posted October 31, 2013 Double checked- I do not see those lines. I also ran short runs to the pins of the chip and did not reinstall shielding. 1 Quote Link to comment Share on other sites More sharing options...

+grips03 Posted October 31, 2013 Share Posted October 31, 2013 I think I'll remove the wires and mount on top of the pins tonight and re-test. Lines are not bad, but if I can remove them completely that would be great. Quote Link to comment Share on other sites More sharing options...
+grips03 Posted October 31, 2013 Share Posted October 31, 2013 here is the pic of the vertical lines Quote Link to comment Share on other sites More sharing options...
SoundGammon Posted November 1, 2013 Share Posted November 1, 2013 Anyone ever try to use SHIELDED wire as opposed to single wires so they would not pick up stray signals and give vertical lines and other garbage? Small shielded microphone wire should work. Where the shield wire is grounded. Extra work but might be worth the effort. Quote Link to comment Share on other sites More sharing options...
+grips03 Posted November 1, 2013 Share Posted November 1, 2013 tonight I tried mounting directly on the video chip, but it was no better. Tomorrow I can try shielded video wire. Quote Link to comment Share on other sites More sharing options...
+grips03 Posted November 1, 2013 Share Posted November 1, 2013 (edited) same results with shielded video wire also tried 3 different s-video cables, same results Issue is present on both the 2 and 4 port Edited November 1, 2013 by grips03 Quote Link to comment Share on other sites More sharing options...
BIGHMW Posted November 3, 2013 Share Posted November 3, 2013 How much would it be for me to get my 5200 (4-port, serial no. 141101, made in U.S.A.) and a couple (or even all 4) of my CX52 joysticks modded with the gold contact buttons and gold flex circuit in each, I know the audio will be in mono, but can I get power, composite video (my Trinitron I bought for use with my unit does not have an S-video jack on it), and both left and right audio jacks installed on that accessory flap (I believe you call it an "expansion panel", which is on the opposite side of where the channel 2-3 switch is)?

ClausB Posted November 19, 2013 Share Posted November 19, 2013 tonight I tried mounting directly on the video chip, but it was no better. Tomorrow I can try shielded video wire. Nine vertical lines only on the left side, right? That's noise from ANTIC's DRAM refresh cycles. Try shorter 5V and Gnd wires. Or move the 5V and Gnd pickups closer to a large cap on the motherboard. Or add a larger cap to the video board between 5V and Gnd. Quote Link to comment Share on other sites More sharing options...

I also tried adding 1uf and 10uf to caps to ANTIC, got same results. Quote Link to comment Share on other sites More sharing options...
