OK, so my initial test board to confirm my spacing was correct came in. My original plan to use headers with the plastic spacers in place didn't work because there simply isn't enough room. I could use the spacers on rows 1, 3, and 5, and then insert bare pins into the spots needed in rows 2...

That’s why I’m proposing two. Simple to have two versions of the Gerber’s, with the board being basically the same, and even possibly you could have a 3-D case that would work for both, with just a wider and taller opening to accommodate both the DB 15 and the HD 15 ports. getting the PCB...

I was certainly planning to put pins in the “extreme” positions. But he outside pins with different spacing are standard 2.54mm spacing, so it should be easy. Originally, I was very concerned about the pin alignment when I was considering a 1-for-1 replacement of the current adapter. Meaning...

Yeah, I was so focused on the 6100 (and its lack of supported resolutions, I forgot about the 7100 and 8100. A universal solution would be fantastic! The 8100 is going to be problematic because of the face that the port section is recessed. I actually have one, but never had to worry about...

What kind of diode would go between pins 7 and 10 to tell the sense lines it should be VGA? And is it really needed here? I actually rigged up a DB-15 to VGA adapter by simply jumping pins 7 and 10. So, if I don't need the diode, it's really easy since DB-15 pins 7 and 10 are pins 9 and...

I think I originally didn't understand this idea, thinking you were proposing mounting a HDI-45 Maile connector, but I understand now - you would simply have header pins mounted at the appropriate locations for the female HDI-45. With long enough headers, this should be relatively easy to...

Exactly, imagine trying to get 10 of these for all the machines I just picked up! I've got a PCB coming that might allow for a replacement male connector, and with that, and a 3d printed case for alignment, the wiring to a DB-15 (or likely even better, a VGA connector pre-wired for VGA/SVGA...

I was thinking of trying to build a set of these. Are there any particulars for the RAM chips to use on it? If you can provide the details, it would be greatly appreciated because I don't know much about electronics, despite being a software developer for 25 years... Thanks!

Just a couple of updates. First, for anyone that expressed jealousy about this find, I would just like to remind you what I'm dealing with. Here was the collection of mice that was given to me in an equally dirty box: I was able to get them all separated, and will have to spend some time...

Looks to be about 32mm.

So with the connector off, and using the HDI-45 to DB15 adapter, I got the spacing, and PIN numbers. This diagram is looking down on the board from the top. It looks like the horizontal spacing matches the actual connector (mostly 2.0mm with some 2.54mm on the right side), and the vertical...

Yeah, that’s my preferred option. PCB design isn’t my forte, so I’m trying to figure that out as I go. Hoping a dual layer board can give me enough room to route the traces in the gaps.

Appreciate the guidance. While I do agree that a VGA output would be ideal, 1. I'm not sure how you'd connect traces on PCBs at a right angle. Pads that line up at the edge of each board? I may see if I can make up a board that simply gives me a DB-15 connector and I'll use the adapter...

Yeah, I have a test PCB on the way that would allow me to match the pin layout of the connector, but there are some challenges, like making the connector durable to handle being plugged in and unplugged, getting alignment perfect to not bend pins on insertion, etc. that’s why I think I’m going...

Ah, so it a used to interface between the control Pico and the BlueSCSI. I may wait until they can have the part, then, as I think I’ll be trying to use that setup (I prefer opening my machines as little as possible due to the plastics). Yeah, I could find a replacement for the LED (although...

@eric I was looking to order a batch of these from JLCPCB and I think I have it pretty well set up, but the LED and the JST connector at J6 are both out of stock. I found a replacement LED, but I could not find a replacement for the 6 connector. The question I have is what is it used for? I...

OK, so I think I may take a different approach. I think a more practical approach may be to build an adapter to mount a DB-15 port in the place of the HDI-45. It won't look as nice from the back, and you'd lose the ability to plug into that one AudioVision14 monitor, but I doubt many would...

Given this is just for the control side of things, I would wager nearly everyone (possibly everyone) has a machine new enough that it can use javascript. Although it might be handy to control is on the device, we already have native apps on vintage MacOS for some of that. Also, many of my...

Yeah, there were marking on them and I assume he picked them up on a pallet in an auction. Cables often get separated from machines. I got a couple working DOS compatible cards, but again, no cables. And the Y cables are expensive and hard to get, so I ended up making some because all the...

Yeah. I have been starting with the 61xx machines. Trying to do a “reverse debt snowball” approach where I’m tacking the machines I have the most of first. So far I think I have about 8 working logic boards, cleaned and recapped. I believe I have enough working power supplies for all the...
