The 1986 retina screen: the WY-700 video card/screen gave the PC a 1280×800 resolution, and a text-mode of 160 columns by 50 lines. It had a built-in 16×16 font (download), and you could even use your own custom fonts. The high-res modes only supported greyscale, but who needs colours anyway?
The three TRS-80 models had no less than 22 different fonts in total (top image), available in Rebecca Bettencourt’s font pack Another Mans Treasure. Shown here are the international fonts from TRS-80 Model 4, and Rebecca’s additions in the last image.
