[. . . ] Section 1. 7. 1 tells how to install SIMMs. The six 72-pin SIMM sockets on board accept single-density (4- and 16-MB) and double-density (8- and 32-MB) SIMMs, with 70-ns or 60ns DRAM speed. These SIMMs may support either EDO or FPM DRAM types, with or without ECC/Parity function. The ECC function allows the system to automatically correct one-bit errors and detect multiple-bit errors. Table 1-3 lists the possible memory configurations.

See section 1. 2. Follow these steps to install a SIMM: 1. Carefully slip a SIMM at a 45° angle into a socket making sure that the curved edge indicating the pin 1 of the SIMM matches pin 1 of the socket. A SIMM fits only in one direction. If you slip in a SIMM but would not completely fit, you may have inserted it the wrong way. Reverse the orientation of the SIMM. 2. Gently push the SIMM to a vertical position until the pegs of the socket slip into the holes on the SIMM, and the holding clips lock the SIMM into position. The SIMM should be at a 90° angle when installed. 1 2 Peg Pin 1 Indicator (curved edge) Hole Figure 1-5 Installing a SIMM System Board 1-13 See section instructions. 1. 9 for the post-installation 1. 7. 2 Removing a SIMM Follow these steps to remove a SIMM: 1. Press the holding clips on both sides of the SIMM outward to release it. Pull the SIMM out of the socket.
