Classic CRT to SE/30 ?

Working on an SE/30 restore and have an opportunity to pickup a Classic (I) for next to nothing. Would make sense just for the extra CRT if its the same or compatible? Also floppy drive etc.

Thanks for any info.

Yes compaible CRT between these which can be swapped, just swap the yoke board over from the other CRT to connect it to the corresponding analog board.

Note here: early built Classic I CRTs are plug-and-play with the SE & SE/30. At some point during their run, they converted the yoke wiring over to what was seen on the Classic II

All the same, I took a similar gamble on a Classic that showed up on the local classifieds.

If the wiring doesn't match up, then its up to you to decide whether or not swapping the yokes is worth it. It takes some adjustment which can be tedious, but it's not impossible. ALSO be aware that you're dealing with lethal voltage. On the assembly line, this adjustment was done while the Macs were powered on (at least with the original Macintosh per historical photos).

FDDs should be compatible. Here's a nice reference for the types of FDDs to check just in case https://siber-sonic.com/mac/superfloppy.html

Sadly analogue boards themselves won't be compatible, but I believe the flyback transformer is, but I can't say 100% off the top of my head. Still worth salvaging.

That's really all I got out of my parts Classic, to be honest.

I just swapped the CRT out of a horribly battery bombed Classic into my SE/30. The floppy drive is compatible, too.
