I finally have a copy of Pacific Seacraft's owner's manual for the PSC 34. This is an electronic copy in PDF format (8,683 kb). I'm happy to share this with whom ever wishes a copy. It's too large for email and I don't have a web site but I could burn it to disc and send it by snail mail.
I too would love a copy (my e-mail is below). I think you can send files less than 9 MB directly. If that doesn't work, you could use the web based program called "SendStuffNow". If you google that, you'll find it.
