| + | Notes |
| + | ----- |
| + | Unless otherwise noted, Apple LaserWriters use 30-pin, 80ns memory SIMMs. |
| + | |
| + | *These LaserWriter printers have the RAM soldered on the board. There are no RAM upgrades available. |
| + | |
| + | %These LaserWriter printers can be upgraded to a LaserWriter IIf or IIg. Contact your local authorized Apple dealer for upgrade information. |
| + | |
| + | The LaserWriter IINTX uses 64-pin, 120ns (or faster) memory SIMMs. |
| + | |
| + | The LaserWriter Pro 600 and 630 use 72-pin, 80ns (or faster) memory SIMMs. If you use a double-sided SIMM, you can only fill one SIMM slot since a |
| + | double-sided SIMM electronically occupies both SIMM slots. |
| + | |
| + | The LaserWriter Pro 810 uses special non-standard 4MB and 8MB memory modules. |
| + | |
| + | The LaserWriter Select 310 uses 72-pin, 100ns (or faster) memory SIMMs. |
| + | |
| + | The LaserWriter Select 360 can be upgraded with a 72-pin, 80ns 16MB (4 Mbit by 32 bit) SIMM with 2K Row refresh (11 bit by 11 bit). |
| + | |
| + | The Personal LaserWriter SC can be upgraded to a Personal LaserWriter NT. Contact your local authorized Apple dealer for upgrade information. |
| + | |
| + | The Personal LaserWriter NT printer's two SIMM slots are treated as one bank; therefore, you cannot combine 1MB and 4MB SIMMs to get a 5MB |
| + | configuration. |
| + | |
| + | The Personal LaserWriter NTR uses 72-pin, CAS before RAS, 80ns (or faster) memory SIMMs. |
