    MC 6800 Emulator for Teensy 4

    6800 Emulator runs on Teensy 4 processor

    ...It supports two modes of operation, an internal monitor program and a mode that emulates the Heathkit ET3400 (and ET-6800) microprocessor trainers. Motorola released the MC6800 chip in 1974. It was a source of inspiration for the designers of the more popular (and cheaper) 6502 chip that was used in so many home computers of that era. The MC6800 is a big-endian processor (hi byte, lo byte order), unlike so many others from that era (6502, 8080).

    Wheefun Computer Prototyping Kit

    A Toolkit for Designing Computers

    ...The ability to do this is useful because a) it allows for tinkering far before physical implementation of the design is. In addition to a strong core, WFCPK will also include modules emulating various processors (e.g., the MOS 6502 and the Zilog Z80) as well as the Video-Audio Interface (a custom VGA-compatible display and audio controller). The VAI is designed to fit within an FPGA to be integrated into real designs. This library is licensed under the GPLv3 but also includes the classpath exception so that proprietary software can be linked against it required.
