I had a B.O.S.S It may still work. Although batteries had to be replaced every 5 years and I have been living here without seeing it. Darn. I last used it as a alarm clock and as a way of calculating years, months, days with a special calender function that I have not seen online much. I think you have to physically ask google the question to get the answer and this was just filling in the dates and hitting the equal button. It had a poker game in it.
My husband had one for a whole 4 days, an older palm pilot. He forgot he owned it and we almost missed an very important appointment. He wanted to try again. I told him his cell phone had a calendar and to use that.
