I tried. In fact I tried the logic board with no floppy drive...

I thought about this as well, since it looks pretty shoddy to me.

I will just wait until I go to my hometown to fetch a 512 or a Plus to test the logic board.

I will try in the next few weeks to Image all the floppies I have here. I have lots of Apple Service Floppies. They might be useful for the folks here.

I also have lots of Old Apple Service manuals Paperbacks I might just scan for the community...
