At first I thought it was merely a branded notebook, with a Sinclair theme. But then I realized it matches the screen resolution when used in horizontal orientation
32 characters by 24 rows (0-31 x 0-23)
I could have used this last year when I was deciphering the mechanics of a hi-res game, i recreated something similar from scratch
