NEC APC

One of the more interesting early machines was Nippon Electric Company's Advanced Personal Computer. The APC was usually offered with the CP/M-86 operating system. MS-DOS 2.11 was also available. The APC is also noteworthy as being of a completely different physical layout to the usual PC-compatible. NEC boards are approximately 12 inches square, it it is one of the few MS-DOS systems offered with eight inch drives.
