Atari 1040STf Reburbish / Floppy Replacement / VGA Cable Manufacturing / TOS Upgrade

I bought an Atari 1040STf quite a while ago and spent several months cleaning it, making an operating system upgrade that allows me to select the TOS version using a switch. I also replace the broken floppy drive and build a VGA cable for it. And I use Retr0bright on the case, failing horribly. So the whole video is a mixture of great success and terrible failure. Enjoy!
