Interesting read. I had the KR7A-133R motherboard as it won Anandtech's gold award for the best 4 bank DIMM support. It was $200 IIRC and was one the more expensive boards. Paired it with an Athlon XP 1800+ and Radeon 8500. Funny enough the AMD naming at the time was to reflect how Athlon's lower clock speed (1.5GHz) was a competitor to Intel CPU's (1.8GHz).
Asus was a strong competitor even then and I remember buying one just a few years before the Abit board that supported SD-RAM as well as DDR as a way to ease the transition for consumers.
It was a good time when IRC, AIM, and physical electronics shopping was still a thing. The only big tech presence that techies hated was Microsoft. Sigh.
