Chapter 1: Product Overview
Introduction
The NCR 7452 Workstation is based on standard PC technology and is
designed to satisfy the needs of the department store, mass
merchandise, and food distribution retail markets.
The workstation features a Series 4000 Pentium III or Celeron 64-Bit
686, or 32-Bit 586 Motherboard with APM compatible BIOS. The power
management strategy is developed around the Intel/Microsoft
Advanced Power Management (APM) specification.
Note: Class 1xxx and Class 2xxx workstations contain 586 and 686
processors respectively. The Class 35xx contains a 686 Motherboard
with an on-board VGA LCD port. The Series 4xxx workstations contain
Pentiu m III or Celeron process o rs.
Note: Workstations equipped with 586 and 686 processors are
designated by "Class" (i.e., Class 1xxx, 2xxx, 3xxx and 35xx). The
Pentium III and Celeron processors are designated by "Series" (i.e.,
Series 4xxx).

7452 -4xxx Celeron, PIII (433+ MHz)
A riser board is available for the Motherboard to accommodate four
industry standard expansion slots (2 AT, 1 PCI and 1 shared AT/PCI),
and 32KB (standard) or 128KB (option) of battery backed CMOS static
memory. A riser board with no CMOS memory is also available with
the new Series 4000.
The worksta tio n has t h ree auxilia ry p o we r ports for peripherals such
as customer displays and 5944 EFT devices. A fourth auxiliary power
port is ava ilable t o power a printer, thus elim in a ting the need for
externa l p o we r supplie s and simplifying ca ble ro u t in g.
Uninterru ptible Power Supply (UP S) prot e ction is provided through a
new power supply with internal UPS function a lity.
The 7452 uses the Retail TAPS software on DOS and Win 3.x, and
OPOS on Windows 95, Windows 2000, and Windows NT.

Graphics (other than Series 4000)
A local bus VGA gra phics controller is used t o pr ov ide C R T graphics
on the Moth er boa r d. It is fully compatible t o the IBM VGA standard
and can be disabled so that an ISA or PCI (except 586) expansion board
can be used as an alternate graphics controller. If LCD graphics for a
Touch Screen, DynaKey, and so on, are required on the 486 or
686-3000, an additional expansion board is required. The 586 and 686
3500 Motherboards have VGA LCD capability built in.
The processor board provides 1 MB of video memory (DRAM), and
can be upgraded to 2 MB (except 586) of video memory. The Class 35xx

Graphics (Series 4000)
An AGP graphics co n t rolle r is us ed t o prov ide LC D and CR T support
on the Moth er boa r d. It is fully compatible t o the IBM VGA standard
and it can be disabled if a PCI expansion board is used as an alternate
graphics controller. The 5953 and 5963 can be connected directly to the
Motherboard. Other LCD devices require a PCI board.
The Motherboard provides 4 MB of video memory (DRAM) and is dual
display (LCD and CRT) capable. The table below shows the resolutions
and color depths available as well as the corresponding maximum
refresh rates.

Power Management
Power management on the 7452 uses the Advanced Power
Managem ent (APM) BIOS Interface Specification R e vision 1.1 as
defined by Intel and Microsoft. The processor board is equipped with
an APM BIOS.
APM defines fiv e sys t em p o wer st a tes :
On
Power on (Maximum Power)
APM Enabled
APM enabled slows the CPU clock and turns off devices
when poss ible t o m inimize power consum ptio n wh ile t he
system is operating.
Standby
APM standby is a lower power state where the CPU clock
is likely t o be stopp ed . No de lay exists when recovering
from this state.
Suspend
Suspend is the system’s lowest power state. A delay e x ist s
when recovering from this state. (Suspend mode is not
present in 586 boards.)
Off
Power off (Minimu m Powe r)
The APM BIOS provides some degree of power management
functionality without any support from the operating system or
applicatio n software.
An APM drive r is be t te r su it e d to mak e p owe r ma nag eme n t decisions
for unique peripherals than the BIOS, and can override most BIOS
requests to go into standby, suspend, etc. APM device drivers
provided by NCR with the 7452 are outlined in the Retail TAPS
Programming Help File.
Workst at ion p owe r on/po wer o ff is con t ro lled th ro ug h a logic le v el
power switch on the processor board. It can be disabled through
software.
