A while back, I found an incredibly good deal on a Sharp MZ-80B system and a host of extras. It included a dual floppy drive unit, as well as the corresponding expansion card so the computer could communicate with the drives, and a lot of floppy disks. What really struck me was how well taken care of this all was. Floppy disk collections this old in Japan almost always come bundled with at least some amount of mold, but the system, drives, and disks were all clean and working.

I booted into Disk BASIC and tested a handful of the games, utilities, and demos that were included on the floppy disks.

A peep under the cover reveals the I/O expansion module and a card with extra video memory, allowing for a higher resolution mode.
