MOS Technology 4510
The CSG 65CE02 is an 8/16-bit microprocessor developed by Commodore Semiconductor Group in 1988. It is a member of the MOS Technology 6502 family, developed from the CMOS WDC 65C02 released by the Western Design Center in 1983. Like the 65C02, the 65CE02 was built on a 2 µm CMOS process instead of the original 6502's 8 µm NMOS logic, NMOS technology, making the chip smaller (and thus less expensive) as well as using much less power. In addition to changes made in the 65C02, the 65CE02 also included improvements to the Instruction pipelining, processor pipeline to allow one-byte instructions to complete in 1 cycle, rather than the 6502's (and most variants) minimum of 2 cycles. It also removed 1 cycle delays when crossing Page (computer memory), page boundaries. These changes improved performance as much as 25% at the same clock speed. Other changes included the addition of a third index register, Z, along with the addition and modification of a number of instructions t ...

Commodore Semiconductor Group
MOS Technology, Inc. ("MOS" being short for Metal Oxide Semiconductor), later known as CSG (Commodore Semiconductor Group) and GMT Microelectronics, was a integrated circuit, semiconductor design and Semiconductor device fabrication, fabrication company based in Audubon, Pennsylvania. It is most famous for its MOS Technology 6502, 6502 microprocessor and various designs for Commodore International's range of home computers. History Three former General Instrument executives, John Paivinen, Mort Jaffe and Don McLaughlin, formed MOS Technology in Valley Forge, Pennsylvania in 1969. The Allen-Bradley, Allen-Bradley Company was looking to provide a second source for electronic calculators and their chips designed by Texas Instruments (TI). In 1970 Allen-Bradley acquired a majority interest in MOS Technology. In the early 1970s, TI decided to release their own line of calculators, instead of selling just the chips inside them, and introduced them at a price that was lower than ...
