Connectors

The MVME187 has two 96-position DIN connectors: P1 and P2.

P1 rows A, B, C, and P2 row B provide the VMEbus interconnection.

P2 rows A and C provide the connection to the SCSI bus, serial ports, Ethernet, and printer.

Adapters

I/O on the MVME187 is connected to the VMEbus P2 connector.

The main board is connected to the transition modules through a P2 adapter board and cables.
