So, I was messing around with my PowerBook 190cs and I noticed in the Control Strip, it allowed me to select thousands of colors. So I selected it... Big mistake! Basically the screen when a slightly odd shade of gray. No problem, I thought, I will restart and zap the PRAM using the...

Adapter worked great. The 3d case did not work as well, because there is very little clearance below the connector. I revised the case to remove the bottom part of the 3d case underneath the male connector that goes into the back of the Mac. For the female connector the cable from the...

PCB arrived. Got the first adapter soldered up and the 3d printed case fits perfectly. May adjust it to cover the edges of the PCB, but it keeps the important bits protected. Haven't tested it yet, but it's a pretty simple setup with a single diode, so I expect it will work. The...

I'm considering it. I have a ton of machines I'm probably going to be looking to re-home and it feels like the best way to do it. The challenge is I have an event the Friday before and it would be a long drive for me to get up there. How's the one at System Source at the end of April in MD...

Ok, I got the wire replaced and I think it turned out pretty good. Definitely like the transparent cable over the stock gray one. The cable is a bit thicker than the stock, so I had to enlarge the hole in the battery compartment to accommodate. Now I need to see if I can replace the mouse...

OK, so sun-brighting has been going well. I've been able to get a bunch of cases clean. However, since the spring weather is cooperating, I decided to get started on my pressure washing of my driveway. And it has me convinced that these machines were not just dirty, but they were likely...

OK, I confirmed it also works with the dips switched around to identify as a 21" multiple scan monitor, which opens up the possibility of higher resolutions. While it won't work on this monitor, which appears to cap out at 1024x768, it may allow it to work with larger SuperMac 21" monitors at...

Yep. that was the approach I decided to go. Grabbed a diode I have for making the HDI-45 adapters and flipped it around to give 640x480 to 1024x768 resolutions. I was able to test it in the house with my LCD and all 3 resolutions worked, but initially I got no signal on the SuperMac. I tried...

I had an adapter like this I used when building out my HDI-45 adapters, except it only had the female connector, the other end had pins but they were too big to fit into the female port. So I grabbed a male connector I had and soldered on the wires and tried to make my own DA-15Male top DA15...

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...
