The Amstrad PCW8256 (word processor) came with 256K of RAM but could be expanded to 
512K essentially by adding another 8 41256 DRAM chips. Some companies in the UK sold the
9-chip kits used to expand PCs (with parity memory) for this, telling you to use the extra chip
to practice with.

However the HP package I mentioned is the only time I've seen one of these dummy chips used
on a production board.
