The Sol-20 had 64x16 text, and unless you polled the hblank signal and limited yourself to poking one character per 50 uS, you'd get snow on the screen. There were others that had the snow problem as well (eg, exidy sorcerer). The TRS-80 didn't have the snow problem, but it too had a 64x16 text display. The PET (which I never used) also had character graphics of the most pathetic sort.
