I fired up Windows 2.03 in DOSBox, with its clock app, available on archive.org[1], and it took up 60.1 MB. This is fun! I think the OS would run fine (at least, enough for the clock) with as little as 512K of ram[2].

If you have screen of size 640*480 and rendering without AA then you can render by CPU. Otherwise, with modern hardware and 200 ppi monitors you will need GPU rendering with the whole infrastructure.
