The 4010 series was also used as the basis for two self-hosted systems. The Tektronix 4050 series used the 4010 or 4014 with internal processors and a DC300 tape unit to produce a simple desktop unit. There were three models in the original 4010-based 4051 with an 8-bit processor, the 4052 with a 16-bit processor, and the 4054 which combined the 4014 screen with the 4052 logic. The 4081 was a version with an Interdata 7/16 minicomputer built into an office desk, which saw limited use. Tektronix continued selling the storage tubes to OEMs, the 19" version as the GMA101 and 102 (the former offering roughly twice the drawing speed) and the 25" as the GMA 125.
