All IBM PCs had much more RAM than 64 kilobytes. A Commodore 64 had 64
kilobytes and cost circa 10% as much as an IBM PC. Some Sinclair ZX81s
and Sinclair ZX Spectrums (also branded as Timex instead of Sinclair)
had 16 kilobytes of RAM and cost circa 1% and circa 3% as much as an
IBM PC, respectively.
