1 Using the SIMM removal tool, remove the DRAM SIMMs from the old logic board and, if they are

1 20 ns SIMMS, give them to the customer.

2 Discard the bottom case. (You need not return it to Apple.)

3 Insert the new Macintosh IIci logic board into the new bottom case.

Replacement Caution: Be sure to insert the replacement DRAM SIMMs (or other 80 ns SIMMs) into the Macintosh IIci logic board. If you use the 1 20 ns SIMMs from the Macintosh Ilex, the new Macintosh IIci will not function correctly.

Replacement Note: To finish the Macintosh IIci upgrade, install the speaker, drives, drive mount (using the new hard drive power cable), power supply, and reset/interrupt switch. (Refer to Take Apart for detailed procedures.) If the unit contains a hard drive, install the hard drive light pipe from the old case in the new Macintosh llci bottom case.
