Motorola mobile radio model number reader

Motorola radios are very solid devices. Nowadays rare chineese radio producs come near to old Motorolas quality. Motorola radios are produced quite a long time ago and there are a lot of different models and their versions (a lot of comunication history ;-). Their specifications are hidden in their model numbers. They are 12 characters long strings. And each character could have a dozen varaints of given feature. So at some point I had tired to look throught those tables and I decided to refresh my knowledges of javascript and write simple Motorola radio model number reader. :)
