The California Technology International MR 2000. I believe these came out in 1979 or 1980, but I need to confirm. Click image for larger view.
My friend Sellam I believe cracked the case on these CTI devices. Rather than video editing equipment, Sellam suggested and I agree that these are actually PDA's! What makes these things so interesting is that they fit perfectly into the continuum of portable computing devices on the way to true laptops. The MR 2000 had no general programming capability and no permanent storage. A year later the 1008-A model was introduced with Stringy floppy tape storage but no programming (BASIC) capability. If this company had continued making these devices, perhaps the third model would have been a real laptop.
