Mac ROM-inator II is Back!
The Mac ROM-inator II replaces the stock ROM in the Macintosh SE/30, IIx, IIcx, IIci, IIfx, or IIsi, adding a bootable ROM disk, 32-bit cleanliness, HD20 hard disk support, and more. I had to discontinue this little guy in February, due to unavailability of flash memory chips and heavy product support needs. I’m happy to report that I’ve found a new flash memory provider, and streamlined the product a bit, enabling the reintroduction of ROM-inator II SIMMs today.
The new version is the ROM-inator II Atom, replacing the old Basic and Mega designs while retaining the same overall concept and compatibility. The contents of the built-in ROM-disk on this 2MB ROM module have been refocused to setup, recovery, and utility purposes rather than gaming. The ROM disk contains:
- System 7.1, with System Update 3.0 and Apple CD-ROM Extension 5.3.1
- HD SC Setup 7.3.5 (patched to support formatting non-Apple hard disks)
- SCSI Probe 3.3 (for troubleshooting the SCSI bus)
- ResEdit 2.1.3
Even when booting from a regular hard drive instead of the ROM disk, you still get the benefits of 32-bit cleanliness, HD20 hard disk support, a boot menu, and custom Happy Mac icon and startup chime.

Hi,
Is there any hope to make rom programming possible directly from the mac in the future? (like rominator for mac plus)
You can reprogram the Atom using the BMOW SIMM programmer or the dougg3 programmer. The Macintosh II logic board doesn’t connect the necessary signals to do ROM writes from inside the Mac.
Does the inability for writes also apply to the SE/30?
It seems that there are some 2Mb chips in stock from certain retailers:

Any plans to re-introduce a MEGA please?
I’ll give it some thought. They quoted me about 2x the previous cost for the 2 Mb chip. I’m not sure if the MEGA still makes sense now that the SIMM programmer is retired. I might be able to make more of the ROM-inator II Basic (4MB total size).
