Cant find the image files anywhere unfortunately. Looking about, i see lots of people that have said they thought there was issues with these chips... however the problems were found elsewhere (of course unless they are missing!)....
I would be interested in these as a long dig into my non working board led me to wonder if U2 and U16 were the issue. I found this option to buy new ones: https://www.ebay.co.uk/itm/222381007177 though they are for revision 3 games.
