I've mocked up a fork of jrouter to make it an AURP access concentrator to see if it would be possible to simplify the setup and maintenance of a GlobalTalk type setup. Instead of every user needing to know and configure every other user's IP address, they only need to configure a single cloud...

DS was very useful back in the day. I miss it. "Modern" MDM management can't match the consistency and repeatability, and is much more hassle some times.

I also have a python-based ImageWriter emulator that can export PNGs or TIFFs (for proper CMYK prints). This year I'm trying to synthesize the sounds of printing based individual impacts. I'll rig it up as a shared ImageWriter on GlobalTalk and maybe have a web page to view/hear the results.

I just verified these measurements on a working, not recapped, 7100/66. I get <1 Ohm between the grounds (5,6,7) and ~13.5 Ohm between a ground and the +5V pins (2,3,4). The other pins (1,8,9,10), are open

Yeah, the Pico W, and Pi 0w when doing the same thing with a PiSCSI, only support 2.4GHz WiFi.

Does it only see headphones plugged in when there are actually headphones plugged in? Could be the jack is stuck in headphone/bypass mode. If the headphone jack isn't misbehaving then my next suspect would be the small power amp driving the speaker. It would probably be closest to the connector...

You're looking for something like this: https://www.amazon.com/Adapter-FIDECO-Converter-5-25-Inch-DVD-ROM/dp/B077N2KK27 The usual caution about random gibberish-named companies, but most of them are probably ok. The 3.5" IDE interface is the key one for your iMac's drive. This one says it's for...

An indirect recommendation: The University library has switched their resin printers to Phrozen Mega 8K's. While the Mega 8K it way out of your budget maybe one of the smaller ones will fit your needs. They run as a retail print service with librarians and student workers, not nerdy engineering...

Congratulations, you have a super rare after market 400k drive conversion! :) My inclination for a hail Mary repair would be to butt the pieces back together and bridge the cut with copper tape, and then try and cut the gap between the traces out of the tape without making things worse. There's...

I replaced most of the caps in the in the PSU but it was still making an odd high-pitched noise before resetting. Ruh-roh, maybe there's a problem with one of ICs died. A little looking around I spotted a thin line in one of the vertical boards. Thar's your problem: I'm thinking the odds of...

How far did you get with this? I just got my hands on one of these and have a G4 I can use to poke at it. Looking at the service manual and looking up the Quantum signal generator I don't think the signal generator knew anything about DDC or any sort of bi-directional communications.

TexElec sells newly manufactured replacement kits that work well: https://texelec.com/product/foam-capacitive-pads-keytronic/

Nice, a 2/10 without the Mac screen modification so you can still run all of the original software with a parallel card so you can plug in the Profile. Do you have the internal Widget drive too? I think that the ROM version on the IO board means it will support 800k dual-sided floppy drives...

Nah, it's just the attention span of a golden retriever. I got the basic functionality going with Basillisk II but didn't push it very hard. I wasn't sure if the stall was an emulation glitch or not then something else shiny crossed my vision. I haven't gotten around to testing it on old Windows.

I suspect that macOS needs the USB to Serial chip drivers installed: https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers?tab=downloads . Windows might grab them automatically through Windows Update
