FWIW, I'm posting this from a Performa 6214 with 48MB ram running OS8.5, from Classzilla. 'Pokey' is probably a good word for it, but it does the job better than most alternatives. Some keystrokes are lost as I type this, when I type too quickly or too far ahead. The auto quote stuff didn't work for me either. But other than that it seems ok.
