You used to POKE memory to change content. And PEEK to read it.
My first memory upgrade was a RAM pack on a ZX81 but added 32KB internally to a SPECTRUM. Seem to recall you added more chips than you'd expect because they were faulty and some memory ignored. I paid a lot for an extra 4MB RAM on my first PC in 1993. But it ran Linux in 8Mb very nicely.
IF DDR3 memory comes down a bit I might swap out the 2x2Gb memory modules in my iMac for 2x4Gb. So might have some spare DDR3 SODIMMs then. Might work in a MacBook if it's a recent one.
