The GW4401A 64-pin ROM SIMM replaces the ROM SIMM of a
Macintosh II-series or Macintosh SE/30 computer.
GW4401A comes preprogrammed with a customized
Macintosh ROM which enables 32-bit clean addressing
as well as a 1.5 MB ROM disk preloaded with System 7.0
and various utilities.
The GW4401A 64-pin ROM SIMM replaces the
ROM SIMM of a Macintosh II-series or
Macintosh SE/30 computer. GW4401A comes
preprogrammed with a customized, 32-bit clean
Macintosh ROM. The customized ROM allows your
Macintosh to use more than 8MB of RAM,
and also features a 1.5MB bootable ROM disk
preloaded with System 7.0 and several utilities.
Ecologically Friendly, Gold-Plated PCB
----------------------------------------
GW4401A 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 RAM2GS II,
and all GW4401A SIMMs are manufactured in our
semi-automated facility in Columbus, Ohio,
in the United States.
Open-Source Design
----------------------------------------
GW4401A'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_.
