Actually in raw clock rate it's only 928 x faster. ?8088s have no cache and take
30+ cycles for an 8 bit multiply. ?With single clock ALU logic, caching,
pipe-lining, super-scaling, branch prediction, hyper threading, high speed bus
interconnects, etc, etc.. The real number is somewhere in the mid to high
hundred thousands of times faster range.

Some of us are actually designing new-old peripherals for the?venerable?old
girls. ?The first prototype third revision (yes third rev) of the XT-IDE boards
will be hitting my door step in a couple weeks. ?And there is a 32MB
XMS/EMS/Conv RAM + 4MB ROM + RTC board ready to go to first spin next week. ?And
an open hardware 8/16 bit ISA VGA card in the works with 1080p HDMI up-scaling
and USB HID K/M support in the design stage. ?A bit sad how some of us spend our
spare time really.

64K was HUGE compared to my first computers!
