Too slow for Wordstar cp/m? Back in the day, I used an Epson PX-8 with dual disk drives and a 128K RAM pack -- all of which I still have. It ran a ROM based Wordstar. If you had a 4 page document and you made a small change in the middle of it, you could hit return then go fix lunch, eat it at a leisurely rate, then fix and drink a cup of coffee and MAYBE it would be finished thinking through the change. And I am exaggerating only very slightly.
It seems a little better on my NEC PC-8500, but I have never done any long documents on it. David Sent from my iPad > On Jun 1, 2015, at 10:02 AM, John R.
