Textboards carried on a large amount of the same culture/posting style and memes as early 4chan, and important to that didn't inherit the retarded culture war mindset that imageboards became known for, with 'raiding' and other loutish bullshit; so a lot of the textboard world has always been distributed among several sites, as were a lot of imageboards back then.

The oldest western textboards still around are probably 4-ch and Sageru. At the height of the times, world4ch with /prog/ might've been the most active western textboard (and /prog/ memes are still noticable among elite programming circles to this day). SAoVQ, Post Office and SchemeBBS are still fairly active as far as textboards go, and a few tend to pop up and die now and then, as is the natural cycle of things. There was a project to revive Tanasinn after it got killed off, which only semi-worked and left it in a mostly broken state, I guess since nobody really cared enough to fix it up completely and were mostly doing it out of posterity.

The extant textboard community, despite its lack of recognition among imgboarders still has a lot of influence: the biggest source of imgboard cancer in recent years got his start from interacting with some of the extant textboarders, before going buttmad and declaring war on them. Unfortunately, a few internet veterans still tend to hold fast against an army of retarded teens, so he got laughed at and fucked off to instead make a couple of the worst imgboards possible. And they were highly successful!
