Upgrade SE to SE/30 while keeping original chassis

As some of you will know, I have an original SE. Its an original, 800k drive, SE. I also have an SE/30 logic board on its way to me, according to FedEx it will be here on the 11th.

I've learnt basically just tonight that the official Apple Mac SE to SE/30 logic board upgrade incorporated a replacement chassis. Just wondering as to what the difference is between the early SE chassis, and that of the SE/30, and how it will affect my ability to do the upgrade. I was expecting it to be as painless as upgrading an LC.

As long as you are not installing anything in the PDS slot , you will be fine with the SE chassis...

I have not looked in the PDS slot to see what is different, but ill try to remember. might be as simple as taking some pliers and bending a tab or some metal out of the way to accommodate a SE/30 PDS Nic.

I actually did this exact upgrade to an SE, which I gave to my cousin six years ago. (It actually got her into Macs--she got her first brand new MacBook Pro last week...)

The board can easily be swapped out--simply remove the SE board and slip in the SE/30. There are two limitations...

1. As others have said, the PDS is different.

2. The SE/30 board only accommodates one floppy drive. If you have a dual-floppy SE (including one modified to have two floppies and a hard drive), you'll have to sacrifice one of them. The SE/30 board only has one connector.

You may want to find a 1.4MB drive, but if you don't, the 800K drive will work fine. I've run other 1.4MB-equipped Macs with 800K drives (notably an LCII which gets used for testing drives) and it works without any problem.

Everything else is 100% compatible--the power supply, analog board, etc are all fine.
