MVME147 Reference
Overview of the MVME147 CPU Module
The MVME147 CPU module provides:
•
68030 processor running at either 16MHz (SRF model), 20MHz,
25MHz (Sx-1 models) or 32MHz (Sx-2 models), with on-chip Paged
Memory Management Unit
•
4, 8 (SA-x models), 16 (SB-x models), or 32M (SC-x models) of
on-board DRAM
•
Four RS-232C Serial Ports
•
Centronics Parallel Printer Port
•
On-board SCSI Interface
•
Ethernet Transceiver Interface (except for -RF/-SRF models)
•
Time-of-day clock/calendar with battery backup
•
2Kx8 Battery backed CMOS RAM (NVRAM)
The OS-9 area of NVRAM is the first 256 bytes of the user area
beginning at address FFFE0000.
•
Four JEDEC EPROM sockets organized as two banks of 16-bit wide
(high and low byte) memory:
• MVME147:
Primary ROM Bank: FF800000
High Byte U1 / Low Byte U2
Secondary ROM Bank: FFA00000
High Byte U16 / Low Byte U18
• MVME147S:
Primary ROM Bank: FF800000
High Byte U22 / Low Byte U30
Secondary ROM Bank: FFA00000
High Byte U1 / Low Byte U15
•
