The Psion MC 400 was a laptop made by Psion PLC and was released in 1989.

The main power is provided by eight AA batteries. Alternatively, the device may be powered by an external 12V power source.

The MC 400 was of the same generation as the Psion 3 series but it has a larger size screen (640 x 400 pixels).[1] The MC 400 could be programmed using OPL much like the Series 3.

Unlike the Series 3, the MC 400 has 4 bays for removable solid-state disk drives compared to 2 on Series 3 devices. The serial port also provides PC connectivity if used with the separately available PsiWin software using the lead designed for the Series 3 or 3A.
