Macintosh Classic repairs: new capacitors, trace repairs, and SCSI repairs 

I got this system back up and running by replacing all of the electrolytic capacitors with tantalum SMD capacitors, patched a trace that was broken, and idiot me almost broke the SCSI portion of the system. I removed that small blob of solder on the chip and it boots up without issues and the speaker works as well.
Stay tuned for another video: fully testing the system and upgrading to System 7.5.X from System 6.X it has installed.
