Filter that can emulate Apple II palette and lofi effects?

I've been impressed recently by gazing at XScreensaver's Apple II module — for anyone who's seen it, it's quite a treat in motion: a simulated Apple II screen comes up, *not* perfectly pristine, but appearing as it would on an old NTSC monitor.

I searched to see if there was an equivalent Filter Forge filter, but haven't found one yet. I think making one that emulates those sorts of classic computer effects (throw in amber PC DOS as a bonus!) would be awesome. Does anyone have any leads in this direction?

Much appreciation in advance.
