Lid back on, function key strip inserted, and the BeebMaster "AIV" (I use inverted commas as I always remind people that my one isn't a BBC Master AIV as supplied with the Domesday System, and which had its own Acorn product code. I don't think I'll ever own one of those, mine is a standard Master 128 + Turbo co-processor + AIV SCSI board + VFS ROM. It amounts to exactly the same thing, but I assembled it, not Acorn!) is upgraded for Domesday XXV.
