Using G-3 PowerBook?

Member Sam Jacobs writes, "Does anyone presently in the MAC Users Group still use the old G-3 powerbook? I know that this system is quite old but it is still functional and I know that someone may still use one of these old units. I have a scanner, a label maker, Epson printer and other hard drives etc. Before just throwing it out, I thought that Iwould ask you if anyone is still using this old machine. Since they are not USB connected, I don't know if there is a converter from the old circular connection that would convert the round to a make it work with USB???
