The first PowerPC Duo, the 2300c was announced in August 1995. Powered by a 100 Mhz 603e processor, the 2300c sold for $3,700 for 8/750, and $4,700 for 20/1.1 GB and an internal 14.4 Kbps internal modem. It was discontinued in early 1997, leaving a distinct lack of Mac sub-notebook machines which eventually would be filled by the PowerBook 2400. Benchmarks
