Motorola MVME187 Board
The MVME187, a single-board computer (SBC), was the first system from Motorola to implement a 88000 CPU, in
this case the 88100. It is, besides the actual MPU, almost identical to its
m68k-based cousin MVME167; both can use the same peripheral and RAM boards. The MVME187 itself is a
single-height 6U VME board. Memory has to be placed directly on this board via so called mezzanine boards,
which were available in two different types and several configurations:
CPU
Cache
- 16KB/16KB or 64KB/64KB I/D off-chip L1
Memory
- Onboard memory expansion mezzanine module with 4, 8, 16, 32, 64 or 128MB of onboard DRAM
- Two mezzanine boards may be stacked to provide 256MB of onboard RAM (ECC) or 64 MB (parity).
Chipset
- Intel 82596CA Local Area Network Coprocessor
- NCR 53C710 SCSI I/O
- 8-bit bidirectional parallel interface
- CD2401 serial (through the PCCchip2)
- 128KB static RAM
- PCCchip2 ASIC (provides interface to aforementioned I/O-chips)
- four 44-pin sockets for up to 4MB on-board ROM/EPROM.
Memory
VME
- VMEchip2 ASIC provides VME interface
- The VME-I/O is implemented via the P1 connector
Misc
- 8 Status LEDs (FAIL, STAT, RUN, SCON, LAN, 12V, SCSI, VME)
- 2 switches (RESET and ABORT).
Operating Systems
- OpenBSD/mvme88k
- Motorola System V/88 Relese 3.2 Version 3
- Motorola System V/88 Release 4.0 Version 3
- Motorola System V/88 Release 4.0 Version 4.0
