"TM32 is Serdaco's latest external MIDI synthesizer! It's very compact, runs mt32-pi and great for DOS games with compatibility of Roland MT-32, Roland CM-32L and General MIDI.
Disclosure: Serdaco sent me this product for free to create a video review. I am not getting paid, but I do get to keep the product.
