GENERAL INFORMATION
SECI'ION 1
1.1
GENERAL DESCRIPTION
The 8025 CRT Terminal is a versatile, simple-to-operate, self-contained
cathode ray tube (CRT) display with keyboard entry that is capable of performing
data processing functions. Capabilities of the 8025 cover a broad spectrum ••• from
simple
teletype (TTY) replacement to ~tand-alone operations.
Primary application for the 8025 is as a remote intelligent interactive
terminal. In this role, it provides direct input of source data via keyboard entry,
in addition to editing, information retrieval, and visual display of both transmit-
ted and received data.
1.1.1
Functional Description
The 8025 CRT Terminal is a computer system designed around an internal
1IIi.croprocesor (CPU) interfaced to memory. The CPU allows the terminal to be easily
adapted to many applications and functional routines without hardware changes. In
addition, data bus organization permits the 8025 to be interfaced to a wide selec-
tion of peripherals such as communications modems, auxiliary storage devices, and
.
printers.
The 8025 Terminal has an ASCII (American Standard Code for Information
Interchange)96- or 64-character keyboard. Keyboard arrangement, shown in Figure 1-1,
conforms with the QWERTY format. In addition, there are 14 special function keys and
~ basic cursor control keys. The terminal also has a l2-key numeric pad.

GENERAL INFORMATION
SEcrrON
On 24-line-per-page terminals, up to 1,920 characters (80 charactersC,r
line) can be displayed on a IS-inch CRT display. Up to 960 characters can be nlS-
played on 12-1ine-per-page termdnals. The basic memory consists of a 1,024 byte
RAM (random access memory) refresh memory and a 2,048 byte PROM (programmed read
only memory) or ROM (read only memory) program memory. Communications I/O (input/
output) interfacing conforms with Electronic Industries Association (EIA) Standard
RS-232C. Additional RS-232 interfaces are included to interface the terminal with
a printer and an auxiliary m~mory.
Paragraph 1.2 gives complete specifications for the terminal.

Internal. Figure 1-3 shows the inside of the 8025. Most of its circuitr
is contained in a card cage that accommodates up to 18 plug-in circuit cards. Im-
mediately above the cage is the CRT electronic circuitry. CRT electronics are ('"
mounted on the chassis and circuit cards. A removable power supply assembly is ,yC;
ted behind the card cage, below the CRT. The keyboard assembly is also removable.

GENERAL INFORMATION
SECTION 1
Nearly all operations in the terminal are controlled by the CPU accorqf'~
to instructions stored in the program memory. Typical operation is briefly desc~e
in the following paragraphs.
The CPU periodically polls the I/O cards and other functional modples on
the bus to find whether any are ready to send or receive data. Assume the keyboard
has data for the CPU. The keyboard intercepts a poll and identifies itself to the
CPU. The CPU then enters the keyboard routine in program memory and enables the key
board to transfer the data.
Following program instructions, the CPU processes the data. If the data
is a character for display, the CPU determines where the next character is to be dis
played and stores it at that location in the refresh memory. The refresh memory can
then supply the data to the CRT display. If the data is a function code (e.g.,
carriage return), the CPU executes the instructions to move the cursor to the start
"#
of the line in refresh memory.
A
data transfer from an I/O interface is performed in the same manner. In
this case, the interface intercepts the poll and identifies itself to the CPU. The
CPU enables the transfer and processes the data as if it came from the keyboard.
Assume the CPU has data for the interface. The CPU addresses, enables, an
sets" up the interface for the transfer. When the interface responds to the next
poll, the CPU places the data on the bus for the interface.
