Info taken from http://www.m88k.com/mvme177.html:
The MVME177, a single-board computer (SBC), was the last system from Motorola to implement a 68000 family CPU, in this case the 68060. The MVME177 itself is a single-height 6U VME board. Two mezzanine boards may be stacked to provide up to 256MB of onboard RAM. The main board and a single mezzanine board together take one slot. The stacked configuration requires two VMEboard slots. The external I/O was implemented via the P2-VME connector at the back of the board. Several breakouts were available, Motorola's 712 boards were the most widely used ones.
68060 at 50MHz or 60MHz, including a FPU and a MMU
8KB/8KB I/D on-chip L1
Intel i82596CA 10Mb Ethernet
NCR 53C710 Fast-narrow SE SCSI controller
8-bit bidirectional parallel interface provided by PCCchip2
CD2401 provides four serial channels
128KB of 32-bit wide static RAM, with 8, 16 and 32 bit addressing, optional battery backup
DS1643/MK48T08 RAM and clock chip
PCCchip2 ASIC (provides interface to aforementioned I/O-chips)
two 44-pin PLCC/CLCC EPROM sockets for SGS-Thompson M27C4002 (256K x 16) or AMD 27C4096 type EPROMs.
four 28F008SA flash memory devices provide 4MB of onboard ROM. Lower 2MB can be overlaid with 1MB EPROM.
Proprietary daughter boards (mezzanine)
Up to 256MB using one or two ECC modules.
VMEchip2 ASIC provides VME interface
The VME-I/O is implemented via the P1 connector
8 Status LEDs (FAIL, STAT, RUN, SCON, LAN, 12V, SCSI, VME)
2 switches (RESET and ABORT).
This particular board is fitted with a 64MB memory carrier module and the 50MHz processor. It is identified as the MVME-177-05 variant (i.e. 64MB onboard).
