Part 1 Model 400t, 425t, and 400dl
The followingsections describe the Model 4(Mlt, 42.5t,and 4tMdlsystems.
Model 400t and 425t Overview
The Model 400t and 42Stsystems are identical except for their @re rocessm
t
and their memo confi rations. The Model 400t uses the MC6803 micropro-
Jrb
cessor and the C6888 floatin -point coprocessor on an emulator board at-
tached to the CPU board. The odel 42Stuses the MC68040microprocessor.
Model 4(K)t s ystems use a 2- or 4-MB memory board in sets of two, which allows
for system ccmfi rations of 8 MB to 32 MB of main memory, in 4- or 8-MB
0!!' increments. M el 42St systems use a 2T,4-, or 8-MB memory board in sets of
two, which allows for system configurations of 8 MB to 64 MB of main memory,
in 4-, 8-, or 16-MB increments.
These systems include the following
. One interface slot for DIO 11or SGC graphics interface boards
. One interface slot for a network controller board (either an 8025 or an
Apollo Token Ring network txmtroller) or an HP-IB interfam board
Systems that run Domain/OS use the network controllers and the Domain low-
:h~tiipke board. Systems that run HP/UX use the HP-IB interface board with
4(% 21A keyboard and other HP-HIL uman Interface Loop) devices.
P
