# 7501/8501 to 6502 Adapter Schematic and Printed Circuit Board
This PCB will allow a 65(c)02 CPU to emulate a CSG/MOS 7501/8501 CPU.

## Theory
The 6502 address, data, and r/w lines are fed through the CPLD so they cna be optionally tri-stated, and the on-board PIO port lines 0-6 are emulated.

## Test
This circuit was sucessfully tested on a Commodore C16 with a SD2IEC floppy emulator.
Some pictures of the circuit installed and running:
