Model 400dl Overview
The Model 400d1is identical to the Model 400twith the exception of the CPU
board. The Model 400dlCPU board doesn’t have the
connectors necessaryfor
internal or external disk drives and some I/O interfaces and memory. As a result,
the Model 400dlconsistsof the followingconfiguration:
A
monochrome 19-inch, 1280x 1024, bit-mapped monitor and graphics
controller
Eight- or 16-MB of memory, by using two or four 4-MB memory boards
802.3network (AUI or ThinLAN, jumper selectableon the CPU board)
RS232(expandable with the optional 3-port adapter for Domain/OS sys-
tems)
Domain keyboard
HP-HIL keyboard and input devim
Audio output for optional external speaker
Note that the Model 4Uklldoes not have SCSI or Centronics parallel external
interfaces, and has only two memory configurations. In addition, thes tern does
not use the single interface slot for a network controller board or an
$
P-IB in-
terfau board.
