By the way, are you aware that the 15-1925 is upgradeable over the telephone? There is a number you can call (during normal business hours), and if they have an upgrade for the device they will play an audio file over the phone. The remote has a modem internally to receive the upgrade. You should call and see if they have an upgrade for the viewmaster. Ask for code CBL/883.

By the way, I'm not even sure what a Viewmaster is. I thought it was one of those things with discs that showed slides in 3d!
