Notes
1. These systems have 32-bit-clean ROMs. Computers with 32-bit-clean ROMs can take advantage of more than 8 MB of physical RAM under System 7 or higher.

2. The ROMs in these systems are not 32-bit-clean, but with the 32-Bit System Enabler under System 7.1 or MODE32 with versions of System 7 prior to 7.1, they can run in 32-bit mode and can take advantage of more than 8 MB of physical RAM.

3. The Macintosh Portable has 1 MB of RAM soldered to the main logic board. You can add more RAM using an expansion card. The Macintosh Portable memory expansion card can have from 1 MB to 4 MB of RAM. The backlit Macintosh Portable memory expansion card can have 1 MB to 3 MB of RAM.

4. If the processor-direct slot (PDS) is used for other peripherals, the maximum RAM is 5 MB for the Macintosh Portable and 4 MB for the backlit
Macintosh Portable, using a memory expansion card.

5. The PowerBook 100 has 2 MB of pseudostatic RAM on the main logic board and one expansion slot. Additional RAM can be added using a RAM expansion card for a maximum of 8 MB.

6. The PowerBook 140, 145, and 170 have 2 MB of pseudostatic RAM on the main logic board and one expansion slot. The 4 MB configuration shipped from Apple has a 2 MB RAM expansion card installed. To expand up to 8 MB, replace the 2 MB RAM expansion card (if installed) with either a 4 MB or 6 MB RAM expansion card.

7. The PowerBook 145B, 160, 165c, 180 and 180c have 4 MB of pseudostatic RAM on the main logic board and one expansion slot. The 4 MB configuration shipped from Apple has no RAM expansion card installed. To expand up to 6 MB, 8 MB, or 14 MB, install a 2 MB RAM expansion card, 4 MB RAM expansion card, or 10 MB RAM expansion card, respectively (note that the PowerBook 145B can be expanded to a maximum of 8 MB).

8. For the PowerBook 165, 165c, 180, and 180c, we suggest 85ns pseudostatic RAM. Use of 100ns pseudostatic RAM results in a performance decrease of approximately 5-10%.

9. The PowerBook Duo 210, Duo 230, Duo 250 and Duo 270c have 4 MB of low-power DRAM on the main logic board and one expansion slot. The 4 MB configuration shipped from Apple has no RAM expansion card installed, while the 12 MB configuration has a 8 MB expansion card installed. To expand your Duo, add the appropriate size memory expansion card.

10. The PowerBook 150 uses Duo type memory. However in order to add more RAM, you must first have a memory adapter installed. The part number for this adapter is M3179LL/A.

11. The PowerBook 5300cs and 5300c come with either 8 or 16 MB of RAM soldered on to the logic board. Either configuration is expandable to 64 MB of RAM.

12. The PowerBook 5300ce comes with a 16 MB expansion card installed.

13. The PowerBook 2300c has 8 MB of RAM on the main logic board and one expansion slot. The 8 MB configuration shipped from Apple has no RAM expansion card installed, while the 20 MB configuration has a 12 MB expansion card installed.

14. The PowerBook 190 and 190cs come with either 4 or 8 MB of RAM soldered on the main logic board and one expansion slot. The model that comes with 4 MB on the logic board is expandable to 36 MB. The model that comes with 8 MB on the logic board is expandable to 40 MB.

15. The PowerBook 3400 and PowerBook G3 utilize 3.3v EDO memory.

16. Refer to Apple's own article 24612: "PowerBook G3 Series: Memory FAQ" for additional information on memory expansion for the PowerBook G3 Series.

17. Due to space limitations, a 256 MB SO-DIMM will fit only in the top slot. The PowerBook G3 Series (Bronze keyboard) uses memory similar to iMac and the original PowerBook G3 Series.

18. The iBook uses 1.25" SO-DIMM for memory expansion. The RAM chips must be 3.3v, 66 MHz (15 ns).

19. The PowerBook (FireWire) uses memory similar in size to the PowerBook G3 Series (Bronze keyboard) but of different specifications. Be sure to use PC100 memory in the PowerBook (FireWire) to ensure proper operation.

20. A 256 MB memory module can be used only if the iBook Firmware Update has been installed; otherwise, 128 MB is the largest capacity module that can be used.
