How interesting. Since you and MDC both say this, I only need one more
person to tell me this for it to be a fact ("What I tell you 3 times is
true."). I was aware of the PDP-11, but no one ever mentioned that the
DEC 10 was the PDP-10.

The DEC 10 was supposed to be able to handle 100 users simultaneously.
Boy, was it slow.

BTW, I didn't use TECO on the DEC 10; I used SOS.
