Apple Mac Portrait Mode Display -- any modern PC and/or Mac graphics cards ?

[frans.g...@wxs.nl]

As a happy (and perhaps addicted) owner of a 1990-vintage Apple Macintosh
Portrait Mode display, I am trying to find out whether there are modern PC
and/or Mac PCI-bus graphics cards available to drive this beauty.

For those of you who did not yet have the pleasure of enjoying the pleasures
of a portrait display, here are some of the relevant technical details:

display area 203.2 mm by 276.1 mm
-- shows a full A4 document page plus menu-bar
640 horizontal by 870 vertical pixels

horizontal scanning frequency 68.85 kHz

vertical scanning frequency 75 Hz refresh rate

dot density 80 dots per inch

dot clock rate 57.2832 MHz

video analog RS-343
sync separate sync, negative going TTL

Thanks in advance for any hints/tips/references.
