Macintosh SE/30 ROM Clips

Trouble with your Macintosh SE/30 ROM SIMM not working? Whether you have a BMOW Mac ROM-inator II that needs a bit of help to seat in the SIMM slot, or if you have a stock ROM with broken SIMM slot clips, these 3D-printed parts can help!

This pair or ROM clips is designed to keep your ROM SIMM firmly seated in your Mac without any paperclips or rubber bands. They simply push down into place, firmly clamping the ROM SIMM into the slot in a vertical position. If you need to remove the ROM, they can easily be uninstalled.

In the SE/30, there are three types of SIMM slot:

• Type A, which uses a white, all-plastic clip.
• Type B, which uses a white, all-plastic clip.
• Type C, which is black with metal clips. Since the clips are metal, this SIMM slot type isn’t known to break, or have issues with the Mac ROM-inator II.

These clips may fit in other Apple machines of the same vintage (such as the IIsi), but have not been tested at this time.

Print instructions

I have printed these with both PLA and PETG. I recommend 30 percent infill (it's hardly any extra plastic) with 0.20mm layer heights, but I'm sure they'll work no matter how you print them.
