New Product Announcment:
7903 MPU with Enhanced Instruction Set

The new 7903 MPU provides a plug-in upgrade for systems currently using the 6502 microprocessor. The 7903 is fully pin-compatible and software upward-compatible with the 6502. Additionally, many of the formerly unused opcodes are used to provide an enhanced instruction set providing features normally found only on much larger systems.
