Step 9: Transplant and Happy Mac
If you are attaching the drive to the internal connection as shown be extra careful due to fragile glass, mains current, and extreme high voltage driving the screen
so if you choose this route do so at your own risk, otherwise there is a external SCSI port for a reason!!
Once the hard drive is hooked back up to the Macintosh computer it quickly boots up into system 7.0
Good Luck! and happy (and safe) retro computing!
