DFW C.I

The DFW C.I was a German reconnaissance aircraft produced during World War I. Derived from the company's B.I design of 1914, the C.I kept the same basic fuselage design, but dispensed with the B.I's distinctive crescent-shaped wings, replacing them with wings with conventional straight leading edges. Engine power was also increased from 90-112 kW (120-150 hp).

The C.II was almost identical, except that it reversed the seating arrangements for the pilot and observer, placing the observer in the rear cockpit and providing him with a Parabellum MG14 machine gun on a ring mount.

Commodore 64

The Commodore 64, also known as the C64, C-64, C= 64, or occasionally CBM 64 or VIC-64, is an 8-bit home computer introduced in January 1982 by Commodore International. It is listed in the Guinness World Records as the highest-selling single computer model of all time, with independent estimates placing the number sold between 10 and 17 million units.

Volume production started in early 1982, with machines being released on to the market in August at a price of US$595 (roughly equivalent to $1,500 in 2016). Preceded by the Commodore VIC-20 and Commodore PET, the C64 takes its name from its 64 kilobytes (65,536 bytes) of RAM, and has technologically superior sound and graphical specifications when compared to some earlier systems such as the Apple II and Atari 800, with multi-color sprites and a more advanced sound processor.

The C64 dominated the low-end computer market for most of the 1980s. For a substantial period (1983–1986), the C64 had between 30% and 40% share of the US market and two million units sold per year, outselling the IBM PC compatibles, Apple Inc. computers, and the Atari 8-bit family of computers. Sam Tramiel, a later Atari president and the son of Commodore's founder, said in a 1989 interview, "When I was at Commodore we were building 400,000 C64s a month for a couple of years." In the UK market, the 64 faced competition from the BBC Micro and the ZX Spectrum but the 64 was still one of the two most-popular computers in the UK.
