Hi Chris,

This is the chip just above the ROMs, to the right of th CPU/VIA. Mine are
marked (C)Acorn and what looks like a VLi symbol? (Picture at http://i743.photobucket.com/albums/xx75/dominicbeesley/vidproc.jpg)

No signs of heatsinks anywhere. 

Dom

One sort of video processor (the older type) needed a heatsink. I think it
was the Feranti ULA version - if you have one of these does it have the heatsink
and if it does it is stuck on with some thermal sticky stuff?
