New Product Announcement: 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. The new instructions are listed
below.
