need video adapter for sh4 HPC Pro

I have a Hitachi EPlate with the infamous sh4 processor. I just bought an old Colorgraphic Voyager PCMCIA card off of Ebay, hoping that it would come with the drivers for sh4 - but no luck. I've tried the Colorgraphic site and downloaded the drivers they post for legacy cards - but no luck there either.

I'm trying to find some way to have a video adapter. I know the Hitachi Eplates originally had accessories you could buy - and one accessory was a serial/vga out converter that attached to the end of the sync cable. But the Hitachi site is little help nowadays and very confusing to find things.

Does somebody know how to get the Hitachi Eplate to do VGA-out?
