That's not good - plenty of SE power ups that didn't trip the electrics... Something tells me that the inrush current limiter is maybe faulty?

Things have taken a bit of a swerve - I never did get around to installing the P620 in the R520. One thing that's happened recently, is thanks to my work, from the legendary E-Waste bins, I picked up a Synology Rackstation RS3617xs+ - a 12 bay NAS with 10GbE (albeit RJ45). On top of that...

Mind if I move this to the 3D printing section?

Yeah sure, i'd love a similar solution for the SE - probably a little easier given the fact it's 1-bit video. I'm not a CRT Purist - as long as its functional and it looks the same - this can serve to save more machines that have duff analogue boards/failing flybacks, but good logic boards...

Yeah you can fix it, literally just need to remove the failed polariser layer, clean the panel and reapply a new polarising film. That being said, it's probably pretty easy to source a replacement panel, as there are only a handful of manufacturers - will probably be either LG, AUO, Samsung...

Because.... Why not? 😂

Just wanted to weigh in here, with regards to anyone thinking of posting here as an alternative, please see our infrastructure overview to get an idea of how TD is setup as a site and what we have in place on the back end. https://tinkerdifferent.com/threads/infrastructure-overview-2021.670/

Looks to be an MFM drive. I'd bet that you're right @JDW in that the drive needs to be low level formatted first.

I'd love to see the end results!

The pdf is in the resource section.

DosFox on the TD discord reverse engineered the SND chip, check there, the schematics and gerbers may be open source.

Would help to know where you're based - due to tarriffs putting the kibosh on international shipping right now, makes sense to recommend services as local as possible.

IIRC @This Does Not Compute tried this with a 540c and....no luck.

If CPU wasn't working you wouldn't be getting a chime, likewise with the GLU - honestly i think it's either RAM MUX/resistor packs, something to do with the PAL logic.

I'd imagine the ROM is fine, given the death chime. When my Iifx went wonky, turned out to be poor oscillator connection and clock signal.
