The Radio Shack 1650 has the same software as SciSys Explorer and SciSys Companion II both of which came out in the earlier part of 1983. There is a difference in the response times however, the Radio Shack 1650 tends to take considerably longer in it's respective levels to move. The computer design is identical to the SciSys Explorer but finished in a dark brown color whereas the Scisys Explorer has a red color.
