Hardware
Hardware projects involving some or all of the gtemuAT67 suite of software.
Arduino Nano
Kicad files for an Arduino Nano USB interface to any decent PC/Laptop to allow the gtemuAT67
suite of tools to communicate with and control real Gigatron TTL hardware.
- Able to reset hardware.
- Able to download and execute code to hardware.
- Able to control hardware with keyboard emulation of the controller.
- Able to control hardware with emulation of a PS2 keyboard, (WozMon, Tiny BASIC, etc).
- Provides a physical and electrical pass through for real controllers/joysticks.
ROM Switcher
Kicad files for a ROM switcher that relies on electrically erasable PROM devices for efficient
switching between multiple ROMS for ROM debugging and development.
- Uses cheap and easily available EEPROMS that are simple and fast to program with a decent ROM programmer.
- Uses a banked design to allow for two separate 64Kx16 ROMS to be contained within two 128Kx8 devices.
- Simple tools allow you to split ROM's into their separate instruction and data counterparts, which can then be
burnt easily into the EEPROMS. - A pass-through socket allows the original EPROM to be part of the ROM switching, effectively allowing for up to three
unique ROM's to be installed. - A simple set of momentary contact switches allow for board reset and switching between the three ROM's, with three different
coloured LED's providing ROM identification.

BabelFish
A bespoke version of BabelFish that allows the gtemuAT67 suite of software to control real hardware.
- Currently works with all versions of known ROM's.
- Provides USB control of physical hardware's menu.
- Provides emulation of PS2 keyboard.
- Provides physical controller pass-through.
TODO
- BabelFish needs to be updated to the latest version.
