This is "Might and Magic: Book One - Secret of the Inner Sanctum," a floppy disk game for the NEC PC-8801, localized by Starcraft.
It is complete with the case and floppy disks, as pictured. It has been confirmed to boot to the title screen; note that only the boot-up was verified and not every floppy disk in the set has been individually tested. Disk A is not the original disk but a replacement/copy. Please review all photos closely for the exact condition.
