Crate sizes

A small cabinet has a 12-position card crate. A large cabinet card crate can hold up to 21 cards.

Card size

A standard ND-100 printed board module size is 366.8 mm x 280 mm.

Connectors

Every card has at least one 96 pin connector (the "C" connector) used for connection to the ND-100 Bus. In addition, a card may have one or two additional 64 pin connectors ("A" and "B"). Connectors A and B are defined for each individual card that uses them. They are used by I/O controllers for connections to external devices.

CPU card location

The CPU module is normally located in position number 1 in the card crate. When the memory management module is present, it is placed in position number 2.

Placement rules

There should never be empty modules between the CPU and the last I/O module. Expansion is from left to right.

Expansion

The ND-100 Bus can be extended to any number of other ND-100 buses by a driver and a receiver module.
