1-2 Product Overview

Part 1 Model 400t and Model 400dl Product Overview

1.1 Introduction

The Model 400t and 400dl systems are identical except for the (Central Processing

Unit) CPU boards. The Model 400dl CPU board does not have some of the connectors

and logic that are available for the Model 400t. This limited CPU board restricts the

conﬁgurations of the Model 400dl to a subset of the Model 400t conﬁgurations.

1.1.1 Model 400t Overview

The Model 400t uses the MC68030 microprocessor and the MC68882 ﬂoating-point

coprocessor on an emulator board attached to the CPU board. The system includes

one interface slot for DIO II or SGC graphics interface boards and one interface slot

for a network controller board (either an 802.5 or an Apollo Token Ring network con

troller) or an HP-IB interface board.

Model 400t systems that are running Domain/OS use the network controllers and the

Domain low-proﬁle keyboard. Model 400t systems that are running HP-UX use the

HP-IB interface board and the HP 46021A keyboard and other HP-HIL (Human In-

terface Loop) devices. The system can also include one or two 200-MB Winchester

disk drives. The display options are a

• Monochrome 19-inch, 1280 x 1024, bit-mapped monitor and graphics control-

ler

• Color 16-inch, 1280 x 1024, bit-mapped monitor and graphics controller

• Color 19-inch, 1280 x 1024, bit-mapped monitor and graphics controller

A Model 400t base system uses 8 MB of main memory. Model 400t systems use a 2-

or 4-MB memory board in sets of two, which allows for system conﬁgurations of 8

MB to 32 MB of main memory, in 4- or 8-MB increments.

The CPU board contains the following built-in I/O interfaces:

• Domain keyboard

• HP-HIL keyboard and input device

• RS-232 (expandable with the optional 3-port adapter for Domain/OS systems)

• 802.3 network (AUI or ThinLAN, jumper selectable on the CPU board)
