64K and cassette IO with Rom BASIC

In 1981 640k was serious capacity. I was using a PDP 11/44 in the
electronics lab at university at that time that had many simulataneous
users and 256kW of memory, so 512kb.

When you start thinking of 8088/86 and 80286 chips you start remembering
the fun of Himem.sys and extended vs expanded memory and all the pain
that brought.

It actually made Win3 arrival quite welcome. At least you could easily
use the memory on your motherboard even if the OS was pish and crashed
all the time.

The Bill Gates quote is bollocks and everyone knows it.
