Programmable flash based ROM SIMM for Apple MAC SE/30, IIsi and IIfx. Make your SE/30 32-bit clean and/or change startup chime, boot icons, etc... bootable ROMDISK available with the 2MB version. Flash chips can be re-programmed individually with a standard flash programmer with a PLCC-32 adapter. The SIMM is also compatible with Doug's SIMM programmer.

The GW4402A 64-pin ROM SIMM replaces the ROM SIMM of a Macintosh II-series or Macintosh SE/30 computer. GW4402A comes preprogrammed with a customized, 32-bit clean Macintosh ROM. The customized ROM allows your Macintosh to use more than 8MB of RAM and features a 7.5MB bootable ROM disk preloaded with System 7 and several utilities.

Newly made memory module manufactured by Siliconinsider. The memory modules have been engineered using high quality 4 layer tin plated printed circuit board with internal power and ground planes for maximum data integrity and low power supply ripple. Each memory modules has been professionally hand assembled using new old stock memory chips, and has been individual tested to pass the standard and extended test in a SIMCheck II.

RaSCSI is a virtual SCSI device emulator that runs on a Raspberry Pi. It can emulate multiple SCSI devices concurrently, provides a control interface to attach / detach drives, as well as insert and eject removable media. Simply launch the software, connect the RaSCSI interface board to your Mac and the devices will be recognized as physical SCSI devices!

MacBatt is an adapter designed to replace the 1/2AA 3.6V primary lithium battery found in many Apple Macintosh computers by a common CR2032 coin cell. The PRAM battery is used to store settings like date and time, time zone, display settings (resolution and color depth), boot disk, speaker volume, 24/32bit memory addressing selection, and more. Additionally, some Macintosh models require a fresh battery installed in order to output a video signal, or to turn on.

MacBatt sits flat in the battery holder and snap securely into place without moving. The contact is made by a pair of gold-plated castellations on the edge of MacBatt adapter PCB.

This coprocessor card have been engineered using high quality 2 layer gold plated printed circuit board and has been professionally hand assembled using new components. Modules are guaranteed to be functional.

The card comes with an unpopulated socket where you supply your own 68882 PLCC FPU, or as an option with an original Motorola 68882 FPU PLCC chip already fitted.
