McMaster-Carr is both the manufacturer and retailer. Search for that part number on this page: https://www.mcmaster.com/catalog/131/3424/92525A205 Pricing is $5.30 for qty 100. If you don't care about them being stainless, mild steel screws would be much cheaper. Note that there's a difference...

Here's a spreadsheet with all of the fasteners I purchased for my SE/30 Reloaded build, which includes every screw in the machine. Some of them are different than the originals but all have the same thread diameter and pitch...

If you're buying through Buyee, definitely pay the extra $15 or so to have them repack the computer. If you don't, they'll just put a new shipping label on whatever packaging the seller used, which may or may not be adequate to survive international shipping. I had a Color Classic arrive in...

I think in most cases it's 0.

Since it's the negative pad that's come off the board, you should be able to get away with tying that side of the capacitor into any other nearby ground.

I had all the internal metalwork in my clear SE/30 nickel-plated too. In the end it cost me $100 but looks amazing just like @Elemenoh 's photo. I think it's worth it (and if you have other frames to get plated or can bring on some friends who do) the incremental cost to add more isn't much.

My educated guess as to what's going on is that the USB cable is acting like a makeshift antenna. The built-in antenna on the Pico isn't great, and the SE/30 has metallized paint on the inside of the case for electromagnetic interference reasons (aka FCC compliance). That's a recipe for poor...

This is the part I used for BU406 when I built my SMC recreation analog board: https://www.mouser.com/ProductDetail/onsemi/BU406G?qs=vNc2DXHODiKv4UObSEVN0A%3D%3D

The PowerCD is just a modified version of the Philips CDF-100. The Philips unit played CDs and Photo CDs, but didn't support SCSI. An educated guess: Based on what I'm seeing on those PCBs, they're getting the raw data from the laser assembly and doing all the "processing" (the larger board has...

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
