interesting. I didn’t realize that was a thing. Should it be able to handle 640x480 if I were to use my DA-15 adapter set to VGA mode? Just trying to see if I can get any signs of life out of this monitor. Looks like it would be a nice one to keep as my primary CRT. But maybe not it if...

So does this monitor require a SuperMac video card? Maybe that’s the piece I’m missing? I just tried plugging it into a Centris 605 I had nearby.

I will likely try to open up the case to see if there are even connections for those pins. I hadn't thought of the dual adapters to basically replicate the sense lines. I don't have a VGA to Mac connector, but I have a female DB-15 connector from my HDI-45 adapters I could probably wire one...

I picked up a bunch of old computers and CRTs late last year. In that haul was a SuperMac 17" CRT. I finally got around to trying to power it on and while it does power on and show a green LED on the front, I get no picture. However, when I turn it off, I do get the lines at shutdown that...

So, I had a coupon for a full color silkscreen PCB from JLCPCB, so I decided to make a special version of the adapter for my own use. The process was pretty easy using the EasyEDA pro app on the Mac, submitting it to JLCPCB was also easy. However, it looks like I may have done something wrong...

So, in preparation for me getting my @MacEffects clear case for my SE, I made my own transparent keyboard and mouse. The mouse was simply a 3d printed replica shell with the innards from one of my many ADB mice. The keyboard was using this design. Because the original CIY Tester68 key...

I have heard this version (590-0322-A) of the adapter allows you to use a IIgs video output with the Extron (more info here: https://www.apple2faq.com/apple2faq/iigs-to-hdmi-using-an-extron-rgb-hdmi-300a/ ) Any chance you could map out the pins on the adapter so I can try to make my own adapter?

So, I've finally turned on my outside water again, and the process of washing individually in the bath tub wasn't working for a variety of reasons, so I decided to give the pressure washer a try. Surely a high powered stream of water would get rid of all the surface dirt and get me a good...

Sure. They’re relatively quick to assemble. DM me and we can hash out the details and I can get the resin cases ordered and any parts I don’t already have on hand.

The 180 requires a buck converter to knock the voltage down to 7.5v, but I've used 20v adapters with my g4 and G3s with no issues, so you could get those a bit cheaper since they just require the USB trigger board. I think the USB trigger boards are ~$3 each, the cables are a usually $3 or so...

These adapters don't have any current limiter, so I wouldn't use it with a portable unless you are using @Androda 's awesome Portable Battery Eliminator. That will prevent it from pulling too many amps. The original portable chargers need to be limited to 1.5A. Someone not sure if there's a...

I received the resin print of my adapted version shown above, which was designed to accommodate the variant of the A9M0050 mouse that has a slightly larger PCB and it seems like it will work fine for both versions. I say "seems" because I can't be sure because I technically cut up the PCB on my...

Looks like your link got truncated.

Which ones would you need? I think I have parts to make some more. I've also started using resin prints from JLC3DP and the finish is nearly professional level. Certainly better than what I can produce with my poorly tuned Ender. I went with the closest without going over for my...

Yeah, my chip didn't look too bad but when I removed it, the legs fell off at the base, making me think the corrosion was worse inside than what I could see. The good news is they are cheap and easily available.

First, I'd recommend changing the title of the post to give people an idea of what you are looking for help with. I saw you post and went to look into my notes to get help, and when I came back, I initially couldn't find you post because the title "Just count on it" didn't provide me context...

Surprisingly, it is not possible to do. I was able to use a Gerber to SVG online tool to make an SVG, and import it into TinkerCAD, but the scale wasn't preserved, so I had to scale it in a way that looked roughly correct. I made a DIY version of your PCB with holes by drilling my own, and it...

Interesting. I didn't think that to try the reboot with the disk image loaded. I always would reset the ESprofile to get back to the selector image. But I'm glad it's not only me, and that there is an easy workaround. Let me know if there's anything I can do to help. I know I still owe...

So I spent some time this morning with it. I created a new 5MB blank disk image. I then used my FloppyEmu to perform a fresh LisaOS 3.1 install. And it worked great. I installed all the apps. However, when I reset the ESProfile and select the newly created and freshly installed LOS3.1 image...

I have what I suspect is a bad PSU with one of my Molar Macs. Not sure the state of the analog board / flyback, but I need to disassemble it again to dig in. I'd love some more info on these to troubleshoot the power supply. Where did you measure the 12/5v voltages?
