One Motorola 88410 Cache/Memory Management Unit (CMMU)
controller with 256-Kbytes cache.
One integrated SCSI–2 narrow (10-Mbits/second) interface
controller.
One integrated IEEE 802.3 Ethernet local area network (LAN)
interface, compatible with thin or thick Ethernet networks
(transceiver not included).
Three asynchronous RS-232-C communications ports.
One integrated RS-232-C port for synchronous communications.
One integrated parallel printer port.
D
Slots for 4 to 12 ECC (error check/correct) SIMMs (single

maximum configurations. Base systems include 32-, 64-, or
128-Mbytes.
D
326-watt power subsystem
D
Two I/O expansion bus slots for optional SCSI or LAN
expansion boards.
