BAMA has the following information:

An Italian site, Marcucci, has a good collection of Icom manuals.

Speaking of ICOM, you can now download manuals on most of their equipment,
both past and present from their Support Page. Furthermore, a note at the
bottom of the page says, "If you cannot find the intended instruction manual
you require on this download page, you can make a request to the Support
Center to have it uploaded." Way to go ICOM!!

For much technical material on ICOM equipment, Adam Farson, VA7OJ/AB4OJ,
runs a site which includes many manuals as well as links to other sources of
ICOM info.

This information may be more helpful than my last post.
