Another reason the 5620 was botched so badly was that AT&T wanted >= $2000 for the development kit (read: C compiler and libraries) for it. Not a good way to get lots of 3rd party application developers on your bandwagon. I used one for a year or so; it was the first windowing system I'd used and the only one I've really liked. For about 10 years I've been using 9wm, which gives a similar feel (at least to me). Those who want to go all the way should adopt 9term as well. (I generally run xterm + bash these days, although for a long while it was 9term + es/rc.) Somewhere, I have an X version of the 5620 font. I found that it wasn't so pretty. I've been using the pelm-latin1-9 font from the sam distribution for years. Norman forgot to mention that the most long-lived split-design application is Rob Pike's sam editor, still available for X11 and still in use on Plan 9. Arnold
