I personally wouldn't put a clear 8 ohm speaker in place of the original, aside from tech specs, the original looks better in a clear case and otherwise I don't want to alter the original timbre. I don't think I've seen anyone replace or refurbish the surround of these particular speakers, but...

Model 4XDC SE Power Supply

Very nice! I have been intrigued by this card for a long time.

Finished the ADB II mouse optical board.

I've also thought about this, and lead to the idea that the easiest way to do it would be to graft certain parts of Cosmic Osmo into expansion rooms. Those two games have the most similar artistic style vs. any of the others. It would be cool if they would release the stuff that never made it to...

@jmacz That's good to hear. I was looking at the analog board while taking some measurements... One thing I saw is the voltage drop at the disk molex connector cable end is not as much as the drop from the PSU connector to the logic board. Also, I didn't see much of any drop (under load) from...

The connector on the board is a DFA and reliability trade-off. If you solder directly to the board, it's recommended to crimp a terminal on the wire before soldering it since the solder weakens the copper strands at the joint. I'm doing some testing of an unrelated design where I solder stranded...

@jmacz That's an epic SE/30 build! Thanks for the shout-out and the trade, it's cool to see the power supply board out in the wild. Your machine features so many hardware projects from different builders in the community. I have the same compact homebrew ZuluSCSI, and I am of similar mind about...

I wanted to throw whatever I could at the new Pacific Pico power supply I designed for Mac IIci type machines to see what it could handle. Here's a demo of the hot-rodded IIci I ended up putting together.

I just ran into this issue of testing a machine with 4x16 MB SIMMs / stock ROM and getting sad Mac chimes with the VRAM herringbone screen pattern. I didn't realize they were 16MB SIMMs but I also don't remember all the nuances of SE/30 RAM configs. But one thing I found in my troubleshooting is...

Agreed, very nice setup. The FPD takes me back. Did anyone figure out how to connect to a Radius or Apple FPD to a modern display?

Sounds like probably any of the Apple 3.5" floppy drives which would be 800k and 1.44MB (400k is rare) and not any of the 5.25" drives except special 3rd party drives.
