Looking for help with Mac SE Radius board/monitor

Having recently discovered this list, I might have a chance at getting some help for a long obsolete Radius product: the Radius Full Page Display for the Mac SE. My late mother bought this a while back, attached to a Mac, for her word processing/typesetting business. It has never worked, due to the fact that the previous owner of the Mac SE formatted the hard disk before handing it over to her. The drivers for the card _were_ on there, but she used the machine for weeks before asking her sons why the big screen initialized but never worked. The external monitor comes up, displays a half-tone pattern, then goes dark. I did manage to get _a_ driver for the card when Radius still had it on their ftp site, but, alas, the ROMs are too old to work with that version of the driver. At the time, my mother didn't want to spend $80 to get newer ROMs from Radius, and now, they aren't available. So... what I could use is either a) an old version of the FPD SE disks (c. 1987-1989) or b) FPD SE ROMs newer than version 4.1 (the ones that are installed there now). Besides the version number, the ROMs have a U number (U19 and U20) and a part number (297-132-D and 297-131-D) and a size (256K). The date on the ROM labels is 1989. The date on the PCB silkscreen is 1987. Thanks for any help. -ethan P.S. - I can burn my own ROMs from images. They're just plain-old 27C256's.
