Most 8-bit computers implemented hardware text mode, and most of those used 8x8 fonts. This was logical for American computers; the title safe area on NTSC is about 200 scan lines; font height 8 gets you 25 text lines, which is the de facto standard. (Or use 192 scan lines for 24 text lines, the other candidate for de facto standard.)
But the title safe area on PAL is more like 250 scan lines. To get 25 text lines, an 8x10 font would be ideal. This would nicely fill the screen, and would also look better. (8x8 is not quite enough to make descenders look good.)
It seems to me that there is a curious absence of this being done.
For example, the PAL version of the Commodore 64, sticks to the 8x8 font, leaving large chunks of unused screen space at the borders. Okay, because the font size on that machine was intimately linked to the graphics modes, changing it would break the ability to import American games, which is a good reason for that design decision.
But the Commodore PET had no such graphical capability; changing the font could not possibly have upset anything, yet it kept 8x8 anyway. Maybe that was because Commodore figured a better-looking display wouldn't gain them enough extra sales to pay for the extra engineering effort; easier to just take the American design straight across.
Much stranger was the ZX Spectrum, which didn't even have hardware text mode, rendered everything purely bitmap, but used 8x8 anyway, using only 192 scan lines for 24 text lines.
The only 8-bit machine I know of to take advantage of PAL resolution was the BBC Micro, and that still stuck to 8x8 for its software bitmap fonts, giving 32 text lines, which at least is using the full resolution of the screen, though creates awkwardness if you want to port software across the Atlantic.
Did any European 8-bit computers use a 10-line font, either hardware or software, to take advantage of PAL displays? (Not counting the later GUI machines where fonts became arbitrarily resizable anyway.)
