I wrote about Teleray terminals:
I'm not sure which model, but it was reportedly
6502-based, and had
some kind of hacked firmware installed. I don't know anything about
the precise nature of the hack; it apparently it was not just a local
hack, but was relatively widely used by Arpanet sites.
Found it. It was a 1061, and the firmware wasn't the stock firmware,
but the modified version actually was from Research Inc., commissioned
by the University of Utah as described in the Usenet article below.
If I had a 1061, I'd certainly want this firmware!

New Version of Teleray ucode available
From FRANK at UTAH-20 Thu Oct 15 22:04:32 1981
We commisioned Research Inc. to develop a new set of ucode for the Teleray
1061, which is now available. It is referred to a Special Feature 720
(ARPANET version), and comes on five 2708s proms, as well as requiring
some trace changes on the main PC board.
Main improvements are:
1) retains all the features of the current "Arpa" ucode (meta key, down line
loadable fcn keys).
2) massive speed up in I/D line. With the preliminary measurements that
I have made, it require only two nulls at 9600 for the worst case I/D
line. This is accomplished by a line map, which is modified for I/D line
instead of actually moving lines in memory. The speed-up amounts to a
25:1 improvement in I/D line performance.
3) Definable scrolling window (a la VT100). One can now set a window beginning
at one line and ending at another, and scrolling only takes place within
that window.
4) The numeric key pad is now soft - the keys correspond to prog. fcns 21-32.
5) A new escape sequence will now clear just the prog. fcns - previously you
had to reset the terminal in order to clear the fcn keys.
6) Status line: pressing "shift rubout" display a status line with baud
rate, scrolling window limits, etc, overwriting (temporarily) the 24th
line.
7) On reset, tabs come up in the position that DEC operating systems
assume they'll come up in.
My understanding is that an upgrade kit with instructions for modifying the pc
board, as well as a new set of ucode, can be ordered from Teleray. Give Dennis
Stollenwork at Teleray a phone call for more info on the upgrade kit. I don't
have the particulars; we basically got one terminal with the changes and are
now in the process of retrofitting all of our others.
