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...

Machine number 2 fully working. I took one of the dirtiest, but otherwise in good shape 6100s, recapped the logic board, cleaned it up and put in one of the DOS Compatible cards. Since no amount of cleaning and scrubbing seemed to get these cases clean, I decided to turn it into a black Mac...

OK, I've been working through my PowerMac 61xx machines that I picked up in my filthy haul a few weeks back. I've successfully built some replacement Y adapters for the ones with a DOS card, but I now have a bigger problem. I currently only have a single HDI-45 adapter that I had with my...

Yeah, creating a blank image is an ok feature, and small file uploads can be handy, but more often than not, I need to load a new image with some additional software or a new OS version to test something. Awesome work, though! Excited to see the changes this can bring!

Just an update, my PCBs came from JLCPCB, I soldered up the connectors I got from DigiKey, and used these cables that I got for $11 each after shipping. I tested all 5 and they all worked well. video out seems fin on both the Mac and the PC side, I don't see any artifacting, but I'm also only...

I hadn't heard of that issue. I have probably 25 BlueSCSIs (almost all v1) and haven't had any issues, although most of my machines on 030 and slower machines. I'll have to keep an eye on it, as I also have BlueSCSI in my PowerMac 6115CD that I've had for a while. I don't boot the machine...

Yeah, that was from the IIfx. I actually buttoned it up after getting it cleaned, working, the case retrobrighted, and the battery holders replaced with a 3xAAA holder I can access without removing the drive bracket. Also, it allows me to put in rechargeable batteries which I've found much...

Feel free to use it. Or I can try to take a better photo once I’ve gotten through all the machines. I’ll also try to grab some better photos of the black one. There’s actually a hole in the side because it was fused to the battery holder and the flathead punctured it as I was prying it loose.

Did you ever get anyone to test these out? I just acquired a IIfx and it only has 8MB RAM. Would love to make a set of these to bump it up. Also, I would probably need assistance sourcing the chips to put on the board.

So, I decided to do some more testing with the board and tried to power it on. A component started glowing, then popped. Turns out it was one of those tantalums (the one at C1). It popped good, and ripped loose a pad when doing so. Fortunately, it appears they designed the board to accept...
