It is a truth universally acknowledged that a computer in possession of some ram must be in want of some more. Thus it was that, in 1983, I purchased eight memory chips for my IBM PC amounting to 64kb of memory, for £80. I opened up the box, carefully pressed in the eight chips being careful not to bend their little legs, worked out the new switch settings for the motherboard to tell it about the extra ram, closed the box, and it worked.
I just upped the ram in my new Dell 2950 from 16 gigabytes to 32 gigabytes, for £18. 16 gb is a quarter of a million times as much as 64kb; the cost was less than a fifth.
I opened up the box, shoved in the ram, closed the box and it all worked.
Kids today have no idea how it used to be.
