I remember it more as a "eight-point" font and its multiple (next ideal being 16-point).
Not in the 90s, but in the early 2000s, I reaped Pixel Fonts' benefit to its fullest. Besides using it as part of the graphics and later sliced for HTML, I used it to render many elements of Apps/programs for Pocket PC devices -- iPAQ[1]. Even though the devices were small, they were handheld and usually used closer to the eyes than desktops, and the pixel fonts were ideal size to give enough spacing and clarity to buttons and even for the smaller text that goes in the mandatory legal writings that need to go with the programs used by Healthcare professionals.
I was lucky to be involved in creating a few such programs for physicians and clinics, making them really happy users. I remember that positioning other fonts (I think, system fonts, etc) was hard to maintain and turned out blurry when deployed to these devices. The Pixel Fonts were crisp and clear when re-aligned after calculating either an even or an odd pixel placement.
It was my second job and first Internet/Web-related Job. My boss was super happy that he spent money on my suggested items, which were repaid repeatedly.
