1.0.2 is the version that shipped on the original disks.

1.0.4 is available http://homepage.mac.com/alk/downloads/MV1.0.4Installer.sit.hqx

The 2.0 beta is available from, surprisingly enough, the wayback machine, http://wayback.archive.org/web/*/http://www.focusinfo.com/support/drivers/MV16%20Updater%202.0.sea.bin
