| 1. | SIMM speed must be 70ns or faster. |
| 2. | This system has four SIMM sockets which are labelled SIMM1, SIMM2, SIMM3 and SIMM4. |
| 3. | The SIMM's are 72-pin and can be x32 or x36. The motherboard design does not require parity checking, hence x32 SIMMs can be purchased (they are cheaper). |
