invisible kid Posted July 19, 2022 Share Posted July 19, 2022 Finally gave this a shot. Not too happy with my work but it does work, so it has that going for it : D 4 Quote Link to comment Share on other sites More sharing options...

invisible kid Posted July 20, 2022 Share Posted July 20, 2022 Reran the wire so it would play a bit better with the cage.(Posting in case it helps other noobs) 1 Quote Link to comment Share on other sites More sharing options...

If not, now would be a good time. ? Quote Link to comment Share on other sites More sharing options...
invisible kid Posted July 20, 2022 Share Posted July 20, 2022 LOL! I was thinking about that but figured I would enjoy it for a bit before diving back in. Got it all back together now. Quote Link to comment Share on other sites More sharing options...
bfollowell Posted July 20, 2022 Author Share Posted July 20, 2022 Out of curiosity, other than running a Sys-Check device without needing to grab power from a joystick port, what purpose would it serve having power on the PBI? Are there other devices that make use of it? Quote Link to comment Share on other sites More sharing options...

It requires the 5 volts to function. Quote Link to comment Share on other sites More sharing options...

I'm very glad I was able switch to PBI power with this mod. Quote Link to comment Share on other sites More sharing options...

I had to go back in for a single flaky 'N' key, so I did this while it was open. I think this guy is set for the moment!

I think this guy is set for the moment! There should be a 100 ohm resistor inline as well. Also, you may want to remove C56. (If present.) If you aren't going to use RF, removing C54 is a good idea as well. 1 Quote Link to comment Share on other sites More sharing options...
invisible kid Posted July 20, 2022 Share Posted July 20, 2022 Ahh, thanks! Will probably wrap it all up today. Quote Link to comment Share on other sites More sharing options...
Beeblebrox Posted July 20, 2022 Share Posted July 20, 2022 @invisible kid I agree with Reifsnyderb, you need the 100ohm resistor in that wire, (where I tend to go in on the top of the PCB, (but that is just me) - I know many prefer underneath the PCB as you have done which is no problem. Just make sure it doesn't snag on anything or the resistor short against anything, (hence heatshrink and/or electricians tape is always good). FYI removing the C54 capacitor as mentoned disconnects the Composiie video too as well as RF. See the following thread below if you would rather keep it just in case you wish to use composite in future, but for the purposes of eliminating jailbars and cross talk caused by composite when using S-video on LCD displays. To do this is simple and instructions on how to install a switch to turn composite on and off, (which also shows examples of the difference it can make on LCDs), is detailed. I do this mod on all my stock 800XLs: Just out of interest for 800XLFs (the 800XL with a Freddie chip), see below where it is the same procedure but with the XLF's equivilent - the C46 capacitor instead: Generally most of the 800XLs I've worked on happen not to have the C56 anyway. 1 Quote Link to comment Share on other sites More sharing options...
invisible kid Posted July 20, 2022 Share Posted July 20, 2022 Yeah, I don't use chroma, I was just going to add it so it would be available. Maybe I'll just add the resistor and call it a day. Quote Link to comment Share on other sites More sharing options...
Beeblebrox Posted July 20, 2022 Share Posted July 20, 2022 @invisible kid No worries. Sounds like a plan. For what it's worth all my A8s run off S-video rather than composite - notably better output than composite and obviously RF - especially when using double sheilded S-video cables. Add the ability to swtich off composite when using an S-video cable on LCD screen and you get a great image - I'll let the images do the talking. S-video outputs on LCDs: With composite circuit on and the C54 engaged as if it was never removed: With it disaengaged and composite turned off, thus eliminating cross talk: 3 Quote Link to comment Share on other sites More sharing options...
