I'm looking for 3 US based people (I'd like to do international, but I don't have the money for it at the moment) who need a replacement hybrid for their M5120 Portable.
I've been sitting on this design since the beginning of the year and I've just now decided to actually do something with it. Recently I put one together and so far it seems to work!
If you're interested, be aware that it will need to be soldered on to the logic board in some way, which will require desoldering the original hybrid.
If you don't feel skilled with desoldering and aren't worried about "destroying" the original hybrid, I would recommend cutting the legs off of the old hybrid and removing the legs with a soldering iron.
I haven't had a lot of time to test things, but so far I've tested the following:
My Portable seems to have some strange hissing sound and occasional variances in audio volume, but I'm not sure if that's the fault of the hybrid or the fact that I had a lot of corrosion in the sound area of the logic board, to the point where one of the transistors fell off.
Other things I have yet to test include serial, ADB, and external SCSI, but I have no reason to suspect any issues with those yet.

I haven't had a lot of time to test things, but so far I've tested the following:
- Boot and install System 6.0.8 (on an original Conner drive)
- Battery meter goes down as the battery drains
- Sleep, power off, restart
- Booting with a RAM card and modem installed
- Booting of a FloppyEmu
