Pardon the correction, but he actually stated the 640K RAM limitation of the first IBM PC based on Intel 8088 hybrid between 8 and 16 bits computers... The real memory mode of the PC only permitted access to the first 1 MB of RAM, and the rest of the 384K was reserved for the BIOS, and various peripheral memory access windows...For more techo geeky stuff, please google the term 'IBM PC real mode": Results 1 - 10 of about 251,000 for IBM PC real mode. (0.22 seconds)
Please don't forget in those days, 8 bit computers had a 16 bit address line (8 bit data bus), limiting the memory map to 2^16 = 65536 bytes of data (64K). So the common CP/M computers of back then were using Intel 8080, or Zilog Z80 architecture CPU's and the Apple IIe, the Motorola 65C02 all 8 bit computers, limited to 64K of RAM (yes that's all). And computers back then also had 'reserved memory areas' including a BIOS PROM reducing the available to less than 64K of RAM, more like 16K of RAM, or 32K of RAM, the ultimate computers back then had a whopping 48K of RAM... I won't mention the others like the Commodore, Amiga, et al. (Funny I just did).
Oh and back then RAM was EXPENSIVE. My first IBM XT with 10MB of HDD, and 640K RAM cost me personally over $8000 ! (And it was a clone no less).
Speaking of which, another famous person said:
I think there is a world market for maybe five computers.

Now for something completely different:
PI says to radical -1: Be real!
Radical -1 says to PI: Be rational!
