For a long time my only "monitor" when I was a kid was a 12" B+W TV for my ZX Spectrum. For the day of my birthday when I got it I was allowed to hook it up to the family 14" color TV, but after that it was back to the B+W for the next couple of years!
(funnily enough, when I finally got a PC years later, the only monitor I could afford was a Philips monochrome VGA -- I guess they now sell for multiples of the original retail price? https://www.ebay.com/itm/176945464730)
