32-bit clean 8 MB ROM SIMM for Mac II series and SE/30 with System 7.1 ROM disk

Compatibility

GW4402A is compatible with the following Macintosh computers:

Macintosh SE/30
Macintosh IIx
Macintosh IIcx
Macintosh IIci
Macintosh IIsi
Macintosh IIfx

Fast Startup

It takes about 10 seconds to boot from the included ROM-based System 7.1, so you can begin working with programs or playing games almost instantly.

ROM Disk Settings

A control panel allows your preferences for the built-in ROM disk to be changed. You can boot from the ROM disk, mount it under another boot disk, or hide it from the desktop completely. Of course, you can always press "R" during startup to boot from ROM independent of your saved preferences. It's also possible to enable RAM disk mode, which allows writing data to the ROM disk, although data stored is not retained between restarts. The RAM disk is enabled by pressing "A" during startup, or by enabling the corresponding setting in the control panel.

Dual ROM Images

In addition to the customized ROM with the System 7 ROM disk, GW4402A also includes an unmodified Macintosh IIsi ROM image. The desired ROM image can be selected using the DIP switch in the upper right corner of the board. Both ROM images can be rewritten using a ROM SIMM Programmer such as the one from Big Mess o’ Wires.

Ecologically Friendly, Gold-Plated PCB

GW4402A features a lead-free, ENIG gold-plated, 4-layer PCB and is fully EU RoHS-compliant. All units are tested extensively before shipment. Only new parts are used to build GW4402A, and all GW4402A ROM SIMM modules are manufactured in our semi-automated facility in Columbus, Ohio, in the United States.

Open-Source Design

GW4402A's design is fully open-source. The schematics, board layouts, and driver software are all freely available for commercial and noncommercial use. To download the design files, visit the Garrett's Workshop GitHub page: https://github.com/garrettsworkshop
