CASIO GZ-50M Sound Module (with bonus item)

Thank you for looking.

This is a MIDI-compatible CASIO GM sound source module, the GZ-50M.

I used it until recently but am now selling it as I no longer need it.
There are some minor scuffs, dirt, and signs of use, but other than the R side of the PHONE output seeming slightly lower, there are no operational issues.

Included accessories: Power adapter (third-party)
Bonus: MIDI interface (recognized and worked on Windows 11)
