Dual Floppy SE Mods.

I just finished dropping a 1.2gb Quauntum Fireball hardrive into my dual floppy SE. I thought it was going to really tight inside the case,but there is lots of room in there! It is running O.S. 6.0.7, with 4mb of ram. It all works well with a really crisp screen, no burn in at all. But it did get me thinking. I came across a stripped dual floppy case in very good condition. I can trade something to get it. I have a SE/30 with a very yellowed case and a bit of damage on the front. Would the SE/30 motherboard fit into the earlier dual floppy case? If it would, then I should be able to put in dual 1.4 floppys! Most of my software is on the 1.4mb floppy. Using the SE/30 board might be easier than finding an accelerator for the SE. Anyone have any suggestions?
Do you need a special drive carriage to hold the hard drive and two floppies or did you mount it some other way?

 
The two floppy drives are in there original holder. The new harddrive slips into the space along side them. I used a thin strip of rubber to keep it snug and reduce any vibration. The newer harddrive was slimmer than some of the older hardrives, so it was an easy fit. I would not turn the computer upside down and shake it, but otherwise, the harddrive stays in place very well.

 
I once saw an SE with two internal hard drives; someone used a bracket normally used for dual floppy SEs to put the second one in with the first hard drive going where the floppy should have been. I think it said on the back that it started life as a no-hard drive Mac.

 
I don't believe any other pre-USB Mac listed here has an external floppy connector, exception is made for some PowerBooks.
I presume you are including the Macintosh Portable (LOL) in the PowerBook category? If so note the following: the Portable uses a full sized DB-19 external floppy drive connector. Any pre-USB PowerBook with an external floppy connector would use the HDI-20 connector and therefore could not use any of the pre-PowerBook external drives, but only special drives made just for the PowerBooks.

This is always a handy reference chart straight from the horses-mouth:

Any Mac with an LC PDS can theoretically have an external floppy drive on it, although that drive will be a 5.25" drive for use with the Apple IIe card. I think I also heard the 3.5" drive for Apple II's will work.
According to Apple, it will not support the 3.5" disk, but rather the Unidisk.

The Superdrive is accessible internally, so it may possibly work externally as well. Interestingly the TIL article doesn't exclude the use of the 800K or the FDHD. However, I would imagine none of the Apple drives would be accessible from the Macintosh side and only within the Apple II emulation, so it's kind of a moot point.

 
Mac LC II, LC III, Colour Classic, LC 500s: Can accommodate one internal and no external drive.
the LC II has solder pads for a second floppy connector and if you solder in another connector you can use a second floppy drive ;)
