Bigger more impressive, often many more knobs and lights :)

Separate preamp. receiver and amp allowed one to upgrade
continuously as funds became available. In the late 60's and
early 70's I built / upgraded my system with my tax check 
each year until my wife said enough was enough and 
forced be to get a new camera the year my son was born.

Then it was lenses and darkroom stuff that absorbed all
spare money until late in the 70's when computers
SDk-80 and EVK-300 became the new black hole to 
throw time and money into :)

First a processor and a teletype, then a second processor and a 
Beehive monitor (8008 based), than more memory, and tape controller
for backup, followed by floppy drives, and ..... Get the picture 

Anyway "all in ones" were what our parents had, and that would not do
we were the woodstock generation and wanted massive amounts of
unusable power ! (until the parents went out, then took every watt we
had to entertain the neighbors :)
