Considering how rare these are starting to get, I hope he says yes. Fingers crossed that the capacitor hasn't eaten too many traces. It looks to be in pretty good shape otherwise. This reminds me I need to make sure I have the right parts on hand to recap my own IIe card here soon.

Got a couple spools in today, and printed out a replacement power button for a 7300. Looking good. Thanks for working to make this available.

I was a bit young when Bill was having his impact at Apple, but Hypercard was still a big thing for young me. It was where I first started trying to build something with a computer rather than just playing with the computer. And much of his work on QuickDraw which I delved into during high...

The goal here is to have a high enough resistance to not conduct, but still not be seen as "open" either. The thing that the AI didn't mention is that the resistance goal is somewhere between 10^5 and 10^12 Ohms, depending on exactly what you are aiming for in terms of dissipation. So >10k and...

I missed out as well, but will be looking to pick up a spool or two once it's back in stock. Meanwhile, it looks like Ars picked up on this too? EDIT: I just rechecked and it still says in stock for me. So I placed an order. Let's see what happens...

I’ve only got a couple spares, so I use the ESD bags I got when buying upgrades off eBay. If I had more, I’d print this out. I stumbled into the thread because it did look like it might be useful a bit later for me. Since I do have a printer though, I can use some PETG-CF I have, or order some...

My one correction here is that ESD bags aren’t RF shielded, at least not intentionally. Circuits generally aren’t vulnerable to RF in the sense of getting damaged, outside of an EMP or similarly strong field. They are vulnerable to an early death if exposed to the couple-thousand volts in a...

I do mention details that are useful specifically for people in your situation. It's why I posted despite failing to post it yesterday when I intended to, and having others post similar information, because there's useful information when you either can't use CF filament, or don't have an...

The ability to dissipate charge without sending it through the electronics. i.e. slightly conductive, but not the point that it could carry any real current. Not sure about the answer to this one, specifically, but one could always print using filament that is slightly conductive. There's...

When the communication is simple serial, the testing costs probably aren't all that high. So long as you decided both platforms would use the same packet format, and the same RS-232 conventions, it wouldn't be hard to test it. And in some ways, testing the Mac implementation against the DOS one...

This makes me wonder if someone has tried to implement mDNS for older systems or not.

Kinda surprised there wasn't something for ADB lying around. But I like putting this I/O on the daughter board, as it means someone can come in and produce an ADB version if they really want one. The irony is that my current setup can convert USB inputs to the original Mac Plus connections, but...

I thought that might be the case, but the ability to focus on things outside of work lately hasn't been great and so I'm not as certain of my thought process in areas where I'm only somewhat familiar as I normally would be. Prolonged stress isn't fun. This really does sound like it'd hook into...

This actually raises an interesting point I'd probably need to dig into, but if someone already knows at least part of the answer, it would help. So it looks like this converter reads in data using the original timings, and spits out a letterboxed version of the screen data using VESA timings...

Test points are vias or pads that can be used with multimeters or other test equipment to check signals or continuity. They are just points in the circuit that can be tapped into. In the case of the 475, the via is the test point.
