187Bug Firmware

The MVME187Bug debug monitor firmware (187Bug) is provided in two of the four EPROM sockets on the MVME187.

It provides:

❏Over 50 debug commands

❏Up/down load commands

❏Disk bootstrap load commands

❏A full set of onboard diagnostics

❏A one-line assembler/disassembler

The 187Bug user interface accepts commands from the system console terminal.

187Bug can also operate in a System Mode, which includes choices from a service menu.

Features

❏M88000 Microprocessor (one MC88100 MPU and two MC88200 or MC88204 CMMUs)

❏4/8/16/32/64MB of 32-bit DRAM with parity or 4/8/16/32/64/128/256MB of 32-bit DRAM with ECC protection

❏Four 44-pin PLCC ROM sockets (organized as two banks of 32 bits)

❏128KB Static RAM (with optional battery backup as a factory build special request)

❏Status LEDs for FAIL, STAT, RUN, SCON, LAN, +12V (LAN power), SCSI, and VME.

❏8K by 8 static RAM and time of day clock with battery backup
