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.

This is looking great. I’d be very interested in building one of these into one of those sub-5L SFF cases.

Very nice. Question I think is: what does certificate validation look like? Do developers need to maintain a copy of root certs at all? EDIT: I see references to a root cert in the readme now, but GitHub is absolutely useless with the line breaks in the source files to confirm.

I agree the match isn't as good anymore, but it prints like PolyTerra to me. Haven't seen the stringiness even when printing at 230C (high-flow nozzle). But I do need to adjust the extrusion multiplier for PolyTerra when printing with a HF nozzle as I get a bit of under-extrusion compared to my...

If you are using a Pi, why not a RS232 hat of some kind? I assume surl-server can be pointed at whatever serial device you are using? The second one linked here needs some configuration of the Pi boot settings to load the driver required, but would let you use a single Pi for a couple of older...

I mean, if you can reverse engineer and/or bypass the right components, you can pretty much do whatever you want once you have the raw pixel data and use whatever timings you like. That's the easy part in the digital domain. You can spit out DVI/HDMI for that matter. This gets into the space of...

Yes. The speaker jack has 5 lines: Ground, Right (In), Left (In), Right (Out) and Left (Out). So the jack is also similar to a switch. No plug? Signal passes from the inputs to the outputs. Plug inserted? The outputs are disconnected/floating and the plug receives the signal. Basically, by...

I'd start by looking at the schematics so you can work back from the jack and see where it gets the signals and pick a spot to pull the signal from. That said, I still think you probably want to pull from the stereo jack or very close to it. The catch is that the circuit appears to be setup to...

CRTs that have aged produce noticeable flicker to me at 60Hz already. I wouldn't want to try to use one at 30-40Hz at all. I once tried a Plasma TV that had to drop to 48Hz to get correct film cadence, and... just no. Some people might be able to get away with not noticing it, but I think this...

Not sure what it was listed for when you saw it, but compared to the other Q650s I’ve seen in the last ~6mo, it was downright reasonable (even ignoring shipping), and in better shape than most to boot. That IIvx they had when I dropped in on the other hand… I’m not sure I’d want to add a CD...
