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 6 and several utilities.
|
|
|
|
|
|
Compatibility
|
|
----------------------------------------
|
|
GW4401A is compatible with the following
|
|
Macintosh computers:
|
|
- Macintosh IIx
|
|
- Macintosh IIcx
|
|
- Macintosh IIci
|
|
- Macintosh IIfx
|
|
- Macintosh IIsi
|
|
- Macintosh SE/30
|
|
|
|
|
|
Fast Startup
|
|
----------------------------------------
|
|
It takes under 10 seconds to boot from
|
|
the included ROM-based System 6.0.8,
|
|
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 hold "R"
|
|
during startup to boot from ROM.
|
|
It's also possible to enable RAM disk mode,
|
|
which allows writing data to the ROM disk,
|
|
although it is not retained between restarts.
|
|
The RAM disk is enabled by holding "R" and "A"
|
|
during startup, or by enabling a setting
|
|
in the control panel.
|
|
|
|
|
|
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 GW4401A,
|
|
and all GW4401A ROM SIMM modules 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.
