Micro Technology Unlimited produced a lot of hardware and software for the KIM-1, SYM-1, AIM 65 and more.
The company is still in business, now sells Karaoke software.

On these pages I have collected what is known about MTU and the products for the KIM-1 (and the MTU-130/140).
With thanks to David Williams, Eric Wright, Dave Plummer, Jack Rubin and Eduardo Casino.
