Yup... I've spent a ton on caps and I don't even have THAT many Macs. $200 for a flyback transformer? Jeez....... sold.

Have you fully recapped it and cleaned all of the analog board? Apparently inconsistent boots can be a symptom of a weak power supply, meaning your board might need recapping or could have some corrosion in places. Worth checking!

Perhaps give https://tinkerdifferent.com/ a go.

Yeah maybe pinwise, but I think the components on the board are also different, so I wouldn't want to try.

https://68kmla.org/bb/index.php?threads/are-the-early-and-late-macintosh-classic-analog-boards-different.46814/ They're really not. I have a Type A CRT and a Type B, and the connectors are incompatible.

The Classic I type A board can't be used with a Type B yoke and vice versa though. My Classic I is a Type B. Anyway, do you have Type A and B PCBs?

Ooh nice. Might have to do that with my Classic type B board if it comes to it. Are there many differences between the Classic I and Classic II board types?

Ooh nice! Any SMD parts on the Classic type B board?

I second this. I lifted a few pads as my iron wasn't hot enough, and I did exactly this. Worked perfectly on my analog board.

Oh right. Sorta skimmed through the post 😅

This is fascinating, and I was only just wondering if Nubus cards were ever adapted for SEs. Very interesting, and would be interested to see if it can be recreated!

Not that I'm aware of. Worth investigating though!

This is amazing! Love this seeing this sort of work. Even my Mum was impressed and she doesn't even know how any of it works.

I can second this 100%. I bought one recently (Donberg no longer has them sadly), and replaced my Grape tray loader's flyback. Went well and now I have a fully working iMac G3 tray, so once I replace the caps on it I should be able to keep it running for hopefully another 20 years! :D

Hey @CYB3RBYTE, any luck with this yet?
