6800/ET-3400 Emulator, designed for the Teensy 4.0/4.1 processors. Build this with the Arduino IDE 2.0. Full Source and readme included in archive. Programs written in 6800 assembly can be run in the emulator. 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).

...An unlimited number of sprites are supported. However big sprites and a large amount of them reduce the frame rate and could generate flickering. When there is enough memory (on low resolutions like 320x200), it is possible to allocate two screen buffers, so to implement double buffering. In this case primitives are always drawn on the back buffer.

OoeyGUI MESS Launcher has been coded by Chris Schneider [SHIFT838] to be a front-end launcher for use to with MAME to easily launch an emulated TI-99/2, TI-99/4, TI-99/4A, TI-99/8 and Myarc Geneve 9640 computer systems. This application has been tested with MAME v0.225b and higher and is completed coded in Python for cross OS compatibility. It has been tested on Windows 10, Linux Ubuntu 20.04, MacOS Catalina/Big Sur and Raspberry OS on RPi4. Please be aware that MAME program switches have changed and this launcher will not work with older versions. ...
