The RM NB200/300/400 Notebook from Research Machines Intel 286/386/486sx

This marked a change of strategy at RM for inhouse hardware design and manufacture, that started with the RM 380Z and ended with the Nimbus range.
The RM NB200, NB300 & NB400 were actually a rebranded Siemens-Nixdorf PCD-2N, PCD-3Nsx and PCD-4NCsx
Other than minor cosmetic differences to the logo brand marks and the screen surround plastics, there appear to be no modifications to the BIOS or motherboard.
