You will laugh. This is an atari 800 and this is the very expensive 16k ram expansion which is the size of a brick. Of course this only stores information as long as there is electricity, turn it off and it all goes away. Silly huh?
And then today we have microSD cards which hold one terabyte, and the data never goes away. which is 62,500,000 times the storage of the brick in case you wondered. Wasn't it AC Clark who said any suffienciently advanced technoloy will appear as Magic. To an old geezer like me its better than Hairy Putter.
