CASIO Z-1 Pocket Computer 16-bit CPU [Before Operation Verification]

This is a Casio pocket computer, the Z-1.
I used this when I was a university student, so it's roughly 28 years old.
I'm selling it because I found it while cleaning up for a move.
It's a CASIO pocket computer Z-1.
I'm currently checking to make sure it works (boots up, key input response, display).

Recommended for those who are fans of pocket computers or who want to enjoy a retro calculator and BASIC development environment.
Although it has more collector's value than practical use nowadays, it still works for hobby development and experimentation because BASIC runs directly on the small chassis.
