  1. What he is saying is that the boards in the XE machines are known for being lower quality. It's really easy to pull up traces and otherwise damage them without the correct tools.

     

    I used a Hakko 808 vacuum desoldering gun to desolder the chips in my 130xe when I socketed it for a U1mb install. Worked great and only took a few moments per chip to desolder.

     

    The key is heat and speed. The more you fiddle with desoldering wick and manual solder suckers, the more you risk damaging the board. Some sort of vacuum based desoldering tool makes quick work of it.


  2. Stupid install question time.

     

    I have a PAL 800XL that appears to have working Chroma on its 5 pin din monitor port, however this machine has not been modded to output Chroma via the monitor port.

     

    I have inspected the board top and bottom and unable to find any of the normal Chroma mods on it.

     

    Also, I built the svideo cable for it and made sure NOT to use composite video as chroma. Just double checked it to verify it.

     

     

     

    Sooooo, my question is, how will this affect the UAV install? I know about pulling up L7 and L9 for Composite video and Luma, but what about dealing with the apparent mystery Chroma?

     

     

    Or am I missing something else?

     

     

    I know the 800XL shouldn't have this enabled (and I have modded a couple 800XL to restore it), but this one has me stumped.


  3. If VGA is good enough, you guys should check out the Micomsoft XRGB-2 up scan converter. They usually sell for around $150-ish used. They are excellent with RGB, composite and svideo.

     

    It does proper scan doubling and has builtin scanlines. I use mine with my 8bit Commodore and Atari machines along with Amiga, ST and consoles. While I usually use RGB from the newer stuff, I do have my C64 and Atari 8 bits hooked up via S-video and I get a fantastic picture on either older CRT pc monitors or LCD screens. Works great with 60 and 50hz too!

     

    I posted a video of the device in action recently on Youtube:
