It was UD5.  The two to the right of it (UD4,UD3) were already empty.  When
you say the bottom 3, are these the ones you mean?  There's also a UD2 at
the very end of the row, but unlike all the others, that one isn't socketed,
so it might not be a ROM at all.

Sorry, when I say "video board" I'm probably using the wrong terminology and
causing confusion here.  I meant the (analogue?) board that sits in the
monitor housing under the CRT itself.  Whatever its name is, I don't think
there's much chance of the display working without it ;)
