The Display/Disk Unit was two 5.25” floppy drives (308K
storage each) and a 12” green monochrome CRT all in one.
This snazzy little unit opened up the world of disk based
software which was required to do any serious computing with the
Sorcerer. These units were relatively expensive ($2,995 in
1980) and probably didn’t sell very well. Working units
are extremely hard to come by.
