Description

The ROMulator is a RAM and ROM replacement and diagnostic board for the Commodore PET, and potentially other 6502 based microcomputers. The ROMulator connects to the 6502 socket in your PET, and the ROMs to use are selected by a dip switch on the board. It allows you to view the memory of a running PET using the replacement RAM by halting the CPU and sending the memory contents over an SPI connection to a Raspberry Pi.

The ROMulator is open source, and the schematics and Verilog code for the ROMulator’s onboard FPGA are available at:
