-[todo]+The **MTU-130** was a 6502 based computer released by Micro Technology Unlimited in 1981. The base system supported 480x256 B&W graphics, 80 Kbytes of RAM, digital audio/speech and included a light pen. An additional 256 Kbytes of RAM could be added as part of a 68000 co-processor card upgrade allowing up to 336 Kbytes of RAM accessible to both the 6502 and 68000 processors. A Z-80 co-processor card and CP/M were available as well. The system required the use of a disk to run as no OS was installed in ROM. The disk operating system was known as CODOS, Channel-Oriented Disk Operating System, and supported 1 or 2 drives and treated all devices as a file.

 +The **MTU-140** was a later model that included drives and a monitor in an "all-in-one" case configuration.
