What this means
The IEEE assigned the MA-L block 00009C to ROLM MIL-SPEC COMPUTERS. Every network interface they manufacture under this block has a MAC address beginning with these digits, followed by a unique per-device identifier. If a device on your network shows a MAC starting 00:00:9C, it is ROLM MIL-SPEC COMPUTERS hardware.
