Hype hype hype! A new sequencer cartridge for the Gameboy Classic has appeared. As the name suggest emulates the sound of the famous TB-303 synthesizer. It can run as a slave to LSDJ or standard MIDI, as well as a master for Nanoloop.
Orders for the first batch of 20 open tonight, so you better be quick if you want one.
More info on the project can be found here.
