Not adverse to using a flat panel and PC hardware.
Been looking for surplus. Pretty slim pickings available.
Hold is required, Clock will not provide control to external devices

Martin,
It seems like the only cost-effective way to get that display is to
find a surplus source. If that's not possible, how about mounting a
flat panel computer monitor on the wall and driving it with some
custom software in a commercial computer with a standard operating
system. There are stan
