===== History and Trivia =====
The Commodore 700 series featured the same hardware basis as the 600 series but had a built-in tilt-and-swivel monochrome 12" monitor, a detachable keyboard and housing for two 5.25" floppy drives.
It was said that the 5/6/700 cases were designed by Porsche, not the more familiar Porsche auto factory, but the separate Porsche Design firm.
Three versions were available:
* 710 (CBM 128/80 in USA): 128 KB RAM
* 720 (CBM 256/80): 256 KB RAM
* 730 (CBMX 256/80): 256 KB RAM and coprocessor
Both versions could be purchased with a built-in dual floppy disk drive which was compatible with the external 8250 dual drive unit.
