A man who owned a small business asked me to program a sales and inventory system for him. He was replacing his old PC and had been running a DOS-based program.
He wanted all the bells and whistles, wanted it browser-driven, with images of all the products in his inventory. But the most important thing to him was that it all run off of floppies his 's hard drive had crashed in the past and he lost all his records, so now he didn't trust hard drives. Not only did he want the whole thing on floppies, he wanted to be able to do a backup onto one floppy every night.
The other thing was that he didn't want to use a mouse or any other sort of pointing device.
