Thanks for the actual product name. A Google search turned up this page:
http://www.linkology.com/daystar/
however, all the links to software and manuals result in a:
"Forbidden
You don't have permission to access /daystar/ftp/documents/ on this server."
So I did a Whois on linkology.com and found Jeff Davis at hostmaster@SOUPWIZARD.COM. I've emailed him to see if there's actually any content behind those links and if I can get access to it. There's a link near the bottom which actually mentions the RAM PowerCard.
