SUBJECT: Procurement of Tektronix Interactive
Buffer
1. The Office of Research and Development gave
demonstrations to me and analysts in my office of the
TACK interactive graphics system developed for ORD by
- I was impressed by the potential applications
of TACK to our problems of data presentation. In order
to use the TACK system on our TEKTRONIX display terminals,
an Interactive Buffer (see attachment) is required. I
request acquisition of one Interactive Buffer for the
TEKTRONIX terminal model 4015-1 located in OSR/S.E/F,
Room 2G40.
2. Coordination of the administrative matters
related to acquiring and installing the Interactive
Buffer will be handled by
R. M. HUFFSTUTLER

Interactive
Buffer
Addition of the Interactive Buffer to
Tektronix 4014 or 4015 Graphic
Computer Terminals produces a
combination of big-screen Storage
graphics and additional features
previously found only in Refresh
terminals. The Interactive Buffer
provides 1023 bytes of off-screen
storage which can be used as a
straight buffer capable of storing or
refreshing alphanumeric or graphic
displays, as a text editor, or in
conjunction with thumbwheels or
an optional joystick, to provide
moveable picture elements.
Buffer Mode Speeds I/O Opera-
tion. In situations where a great
many I/O commands tend to slow
down operations, the normal Buffer
operation is a special advantage,
since the computer can dump the
I/O strings in the Buffer (and dis-
play them on screen) much faster
than they could be sent to the
Terminal one character at a time.
During Buffer operation the terminal
keyboard is locked. The terminal is
suppressed, and characters re-
ceived from the computer or a
connected peripheral are stored in
sequential Buffer locations, starting
at location zero. The contents of the
Buffer can then be displayed on the
Terminal screen on either a stored
or a non-stored, write-thru mode.
Text Editing Added to Storage
Terminals. The Interactive Buffer
adds text editing capability to
Tektronix storage terminals. In
Compose Mode, previously entered
or keyboard characters are dis-
played on the Terminal screen
normally beginning at X = 0, Y = 33,
but not sent directly to the computer.
The alphanumeric characters can
be deleted one at a time from last
character position using backspace
and new ones written in, or the
entire Buffer contents can be erased
and re-written. Once the text is
correct to the operator's satisfac-
tion, a carriage return causes the
Terminal keyboard to be locked and
the contents of the Buffer sent
to the computer.
Relocation Graphics Give Ter-
minals new Power and Versatility.
Relocation Mode with the Inter-
active Buffer increases the graphics
power of the Tektronix 4014 or 4015.
When Relocation Mode is activated
via keyboard rocker switch, Graphic
information in the form of a simple
pictorial display, or a small part of a
larger one is entered in the buffer.
It can then be displayed on screen
in a non-storing mode and moved
to various screen locations by the
use of the thumbwheel cursor, or
optional 4952 Joystick. Approxi-
mately 160 alphanumeric characters
or 480 centimeters of graphics can
be displayed without flicker. The
repositioned display can then be
stored and the reference coordi-
nates sent to the computer using
the crosshair cursor. Relocation
Mode provides a means of editing
or composing graphic information
without erasing the display and
starting over.
Additional Modes for other Ter-
minal Functions. HOLD Mode is
entered any time a Hard Copy is
commanded. It amounts to a
temporary suspension of the
non-storing, write-thru Mode during
Hard Copy operation or some other
special function. STORE Mode
locks the Terminal keyboard, and
causes the Buffer contents to be
sent once to the Terminal screen
and stored. NEUTRAL Mode permits
