    The Apple III (and III Plus) strictly emulate a stock Apple II Plus.
Therefore: 48 K RAM, 1 MHz operation, 40 columns white on 
black text in uppercase only, High and Low Resolution graphics. 
Color is unavailable on an RGB display, however it is possible 
(with some trickery) to get color graphics through the III's 
monochrome-out connector from what I remember.

    None of the advanced features of the Apple III will be available
as there's actually specialized hardware logic to block them out.
Titan produced a plug in card that allowed you to emulate a true
Apple IIe, if you can find one these days. The built-in Disk III will
work (not sure about an external) but doubtful the serial ports will.

    I was more interested in exploring the Apple III's native side but 
never found much software for it, I only have a little over a dozen
floppy disks. To this day still wonder if anyone produced a game
or music program for the III...
