Well calling an Apple a PPC would have been rather confusing in the  
day when Apple's ran on a 6502 CPU!

In the beginning they were called generically 'microcomputers' in  
order to differentiate them from mainframe and minicomputers, which  
were still very large devices owned by universities and corporations.

The abbreviation 'PC' specifically identifying DOS-based (and later  
Windows-based) computers dates back to the introduction of the IBM PC.  
(I was there at the time...I remember a buddy of mine who was an  
engineer fro IBM coming home excitedly one day with a big white box  
with a couple of floppy drives in it and that distinctive IBM green  
phosphor monitor. He was one of the lucky IBM employees to get one of  
the first ones off the line at an employee discount. He'd splurged and  
got a whopping 64 megabytes of RAM in his.)

Initially 'PC' ONLY referred to the IBM system; later systems that  
were compatible were called 'PC-Compatible'. They ALWAYS ran MS/PC-DOS  
and were based on the 8088 chip.

All computers at the time were called by their manufacturer's model  
names: Apple II, Commodore 63, TRS-80, and on and on. At the time IBM- 
PC was only one of the many such models.

As the PC and it's clones came to dominate the industry, usage slipped  
and 'PC' came to identify any Windows or DOS-based 808x system.

It was NEVER used in the sense of 'all small consumer-owned  
computers', at least not in the computer literature of the time.  
Anyone referring to PC's in that fashion pretty much believed that all  
such computers WERE DOS/Windows-based systems.
