  • The Processor: 20Mhz Motorola 68030 model # MC68030RC20B

  • The Onboard RAM: 1MB Soldered the the logic board.

  • RAM Slots: 4 30-Pin DIMMs installed in pairs.

  • ROM SIMM Slot: If your computer doesn't have one if these (and it works) , it doesn't need one. If it has one, it needs it in order to boot.

  • PDS Slot: For Attaching a riser card containing a math co-processor. A PDS card can then be plugged into the riser card. PDS - Processor Direct Slot

  • Power Supply Connector: for direct connection to the power supply.

  • "VSLI" chip: This machine's equivalent of a "Northbridge" It manages RAM, PDS, and the external ports.
