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...

Since I'm kicking everything through an upscaler to an OLED, not much point in doing dual monitors in my case. Sure, it's not as authentic, but it's a lot easier on my eyes. Helps that the upscaler can be configured with optimized timings for the different Mac display modes of the era.

Just to clear what seems to be confusion, I have both a Quadra 605 and 650 now, so discussion on what to use the expansion slots for was aimed at the latter. I should probably update the title maybe. :) For the 605, I've got a IIe card that isn't going anywhere (except maybe removed briefly to...

That is a thought for sure. With the spare PCI Orange Micro cards I have, maybe could trade for one in decent shape. EDIT: I ran across your thread where you were getting this card working in a 700 while looking deeper into this. Don’t see why it wouldn’t work in the 650/800 as well. That’s...

May as well put this here as well, but I found the other Quadra I’ve been hoping to get a hold of.. a 650. Owner took good care of this one, so just a bit of yellowing on the case and some dirt to clean. Only 12MB of RAM, but that can be upgraded. Somehow the Quantum drive still works too. Not...

Probably this then? https://everymac.com/upgrade_cards/sonnettech/crescendo_g3_l2/crescendo_g3_l2_400.html To my knowledge Power Computing never made upgrade cards, just clones. The 210 and 180 would have been 603e/604e CPUs meant for their systems and probably removed and sold when the...

Oh man, been a while since I’ve seen a joeCARD. It looks like most of these are for the OldWorld PPC Macs that came with CPUs on the daughterboard (pre-G3 era). Others look like CPUs that would have come with a system. So you’d probably need someone with access to a couple different systems to...

I would generally agree here, except Crucial seemed fit to issue a warning and say that warranties wouldn’t be honored in the case of a melted adapter. Does make me wonder what their support staff saw that made the company deem it worthy of the effort to write up a support article on it. That...

Correct me if I'm wrong here, but this test looks to be more affected by static pressure than airflow? You're creating resistance that the airflow has to overcome (the paper blocking the outlet), which is important if you are pushing air through tight spaces like a modern radiator in a liquid...
