The FZ-35S was a kiosk style system manufactured by Panasonic for the commercial side of business. This system features typical M2 hardware plus some for IDE devices and Zip. The system has S-Video, Composite, and VGA RGB. This particular system is able to play unencrypted titles of released betas/alphas, but not arcade titles.
The FZ-21 is another M2 kiosk unit, except it uses the cancelled retail housing and features a memory card slot.
