Hello my patrons! Continuing with the BBC Master 128 series, now the machine is working perfectly and looking clean and shiny, I decided to give the computer some mods and quality of life improvements.

Some of these mods might be a first for this machine, like converting it from PAL to NTSC and removing the external CMOS/Clock battery I had installed in part 2. I figured out all of these mods as I made this video, so a lot of the time while recording, I wasn't sure if any of them would work!

PS: This is densely packed video -- I could have split it up into 3 or even 4 parts like many other YouTubers, but I decided too just stick it all into one video. There will be time links in the description to jump to specific parts.

Please let me know if this is too long and perhaps I should split it into two parts!
