  When I saw you snap the RAM into place after putting the board in so you could clear the screw mount, my first thought was this: "how in the heck does he ever intend to get it back out?".

  Top tip with those PPC cards - the PPC CPU in there is actually rated for 75MHz - they're capable of more than 66MHz. They take the bus clock of the 040 and double it to derive the final frequency - do the spicy o'clock mod on there to tweak the bus speed to 37.5MHz and you should have a 75MHz PPC - you could probably put 40MHz through it, but at 37.5MHz, you wont need funky VRAM, or experience issues with the serial ports. Go on, you know you want to ;)

  <a href="https://www.youtube.com/watch?v=ApgiLPsyOVA&amp;t=585">9:45</a> you need to be SUPER careful when pushing those LC/Performa logic boards into those rails of darkness: one minor misalignment and you bend/crack the delicate golden contacts on the edge, rendering your board useless.I&apos;ve seen a couple of machines in that era with destroyed contacts on that long delicate edge row.Great video as usual!

  Boy, having grown up in the 2000s, it&apos;s surreal seeing someone actually... swap out components and cards on something made by apple.

  So it&apos;s essentially a bus-contrained PM6100 in a cute form factor. &nbsp;Nice!

  This mod resembles me in 1997 when I purchased an Amiga PPC accelerator BlizzardPPC with a 68060@50Mhz and a PPC 603e @ 240Mhz with 128MB EDO RAM. I added the BlizzardVisionPPC Permedia2 3D card too. It was a frankenstein! 68K and PPC in the same architecture!!! Thanks dude!

  Wow Sean, I had no idea there was a DayStar PPC upgrade for the 575 board! Now you are giving me ideas on what to do with my other Color Classic. &nbsp;Great video!

  It would be fun to see OS X on it now that it has a PPC processor. Although I think X needs a monitor that is able to output at 800x600.
