MS-DOS 3.2; curiously, at around the same time Research Machines were
shipping the Nimbus range with MS-DOS 3.1.  Always amused me; 3.2 was the
first MS version to support 3.5" floppies AFAIK, which the Nimbus had but
the PC1512/1640 lacked!  Yes, I'm a bit sad like that.

640x200 in 16 colours (4 planes), and that was the PC1512.  The PC1640 had
an EGA-compatible adapter onboard, which could be configured for various
modes of operation (CGA, EGA, Hercules, possibly the PC1512's 16-colour
CGA?) with DIP switches on the rear panel.

Yes, I'm looking for a distraction with my afternoon coffee, why do you ask?
