My first computer was the Sinclair ZX81, with 1K of memory. Yes, 1K, 1024 bytes. Not 1M, no. Nor was it 1G. A couple of years ago, I bought a new motherboard and processor, Sempron 2800, nice and quick, "Ooooh", thinks I, "I'll get a *gig* of memory!" So, 60 quid for the memory alone, I now had *one million times* as much memory as my first ever computer. I had to buy another processor and board a couple of weeks ago. Actually, I had to buy a new graphics card, but since I needed a PCI-E board for it, that had to come to. A gig of RAM is now 20 quid. So, for 1/5 of the price of my first computer, bought around 25 years ago (scary!) I have a million times as much memory. Let's not even discuss the 750G of disc space spread (thanks to raid loveliness) over three spindles with 1-of-N redundancy... The TI99-4a was an interesting beast. 256 bytes of memory addressable by the CPU, and everything else was accessed through the graphics chip. I kid you not.
