Morrow Information Systems S-100 backplane labeled MIS PDC Mother Board part number 670-5313-00. Board is date marked 1977 and remains in clean condition.

Master/Slave Bus.

This is a full 20 slot S-100 passive backplane featuring clearly defined DBUS, master section, and slave section layout. This segmented bus design is typically associated with higher end S-100 systems and was intended to improve signal integrity and support more complex multi board configurations.

The board includes high quality gold contact connectors across all 20 slots, heavy copper bus distribution on the reverse, and both screw terminal and Molex style power input options. A labeled PROM PRGM header is present, suggesting system configuration or development capability.

Contacts are bright and unworn. No signs of oxidation, or repair. Board surface is clean with no visible damage.

This is a scarce early Morrow backplane in excellent condition and would be ideal for a high end S-100 system build or collection.

Functionality has not been tested and it is being sold as is due to age.
