It's true. I found one at a local (Silicon Valley area) Radio Shack
and was considering purchasing it as a spare, but it was a returned
model and it didn't work. They are fairly scarce in this area -- only
two were shown in the entire district's inventory system -- so if you're
interested in getting one, have your local store check the regional
inventories and save yourself some driving. It's not in the 1995 catalog,
so you may need to tell them that the part number is 25-3100.
