Most of that old software used in chat rooms were just hacks. Extremely unlikely to be hosted on OldVersion.com.
Without a website, or info to the Motorola Power Tools, nothing can be hosted, you must fill in the proper information, when you request a title.
Look in the Request board, at the top, notice How to Request an App, read it, format your question accordingly. Then who knows. But I am sure it is not going to be hosted on the main site. You might find a link in the forum, if and only if the software in question is legal to be shared, such as being under a freeware or shareware license, probably not. Its probably just for owners of the particular product.
There already are sites which hosts practically unlimited drivers,
