Also it should be noted that the internal and external floppy drives are gummed up... Won't allow me to insert a disk. Anyone remember the thread how to clean and lube these old 400k drives?

I don't remember the thread, but I cleaned a few of them back in the 90s. I got some new-from-Apple but had been in the wrapper for close to a decade 400K drives. They were both frozen solid. The lubricant had turned to lacquer.

The stuck mechanisms are the metal slides on the sides of the drive. Take swabs soaked in alcohol and clean all the gunk off of the slides on the sides of the drives. Clean every moving part you can find.

After you have the drive sliding and accepting disks again, re-lube the moving metal bits with a lithium-based grease. That should last longer.
