I thought a little company in NY (whose name I forget) had the contract?

Another significant difference between the Blit and the 5620 would seem
to be the color of the display; didn't the Blit have a white phosphor?

The word size difference shows up in the existence of both texture
and texture16, yuck.

That's probably my fault; I have referred to this as /dev/proc a few
times.  It seemed to me that calling it /proc wouldn't convey the
special nature of the /proc filesystem type.

??  How do you get the /proc entry open etc. in the first place,
except from a Blit-like terminal where you already have multiple
processes?  It seems to me you need to press some key on a normal
terminal.

Yes, yes!  When will this be generally available?
