I don't have an exact part number for you, but I measured L202 to be 0.4uH. Inductors of that value appear to still be common today, though what current rating that one is capable of I'm not sure.

It's likely supply and demand. I've long suspected those sockets are NOS parts, and now that there's increased demand and supply is shrinking, they're going to price them accordingly. Long-term, we'd need someone to bankroll having a manufacturer start making the sockets again -- but given the...

I couldn't remember what it topped out at. Either way I had it set to something like 75-80% of maximum.

Pretty sure it was the stock 1mm nozzle, with the heat set around 4 (out of 5). I don't remember ending up with any particularly stubborn pins, so maybe I just got lucky!

I've removed a soldered-on CPU from an SE/30 with just the FR-301, it's totally doable. You can buy new sockets here: https://www.peconnectors.com/sockets-pga-cpu-and-memory/hws4514/

Here's a BOM I put together for building Kay Koba's SE analog board recreation PCB, but it's valid for original boards too: https://docs.google.com/spreadsheets/d/1PwaqRaqlt8nKqXaVAkaXogw2BTpqbcQ4xXxHejsVk5U/edit?usp=sharing

I'm locking this thread as it's already diverged from its original purpose. Tinker Different is not affiliated with 68kMLA and we can't answer to how their operations work.

Sounds like a layer 2 issue to me. I'd try setting up port mirroring on the switch interface you have the Mac connected to and see what shows up in Wireshark.

Not sure which Google Sheets BOM you're referring to, but here's the one I put together when I did the group buy: https://docs.google.com/spreadsheets/d/1Nx-KRaF5cdhcJSdrX42SqrtQcKcN2UZhHbEiThW19gc/edit?usp=sharing

Your IIfx has the same weirdness as mine: All of the SMD caps are tantalum except for those two electrolytics over by the RAM slots.

The biggest one is that the ring light that ships with it, at least for my unit, has its own (somewhat short) mains AC cable. I ended up finding an otherwise identical ring light on AliExpress that's powered by USB and can plug into the USB-A port on the back of the microscope. The other, lesser...

I use one of these and while it's not perfect, it works great.

I'm curious how this even works -- are the EGRET/CUDA chips also part of the system memory space?

Thanks, I've gotten this one added to my spreadsheet. Do you happen to have a recommendation for Y2 as well?

The best option would be to get it sandblasted (to remove all the rust) and then either powder-coated or plated (nickel, zinc, etc). You could try to sand the rust off but it's really difficult to remove it inside all the pitting. An alternative would be to keep an eye out for another chassis in...
