Ah, yes...  I had nearly forgotten about that.  I recall having
trouble doing asm video programming because of some hardware cost-cutting
thingie, something about a wierdly wired bunch of NOR gates or
something...

But anyway, I take it that this would be the cause of the minor ghosting
and shadows that I noticed?  The video card that I will be using in my
wearable is an old CGA card with an NTSC output, so I assume that the
wearable will be clearer than the Laser was (though the Laser really
wasn't that bad).
