    Apple Lisa Mouse A9M0050 - Replacement Shell

    Yeah, unfortunately, my filament printer can't come anywhere near the quality of a resin print, and I don't really want to purchase one and deal with all the chemicals and processing. Also, when I can get one printed in resin for ~$20, it doesn't even make sense for me to buy a resin printer at...

    Massive (filthy) find in South Carolina

    Ah, sadly no, just a footnote in this post. Used the same paint as the G3 all-in-one. I've not done a great job documenting because I'm a bit overwhelmed with projects at the moment. Spending lots of time trying to build a video out solution for the 6100s so their new owners don't have to...

    Apple Lisa Mouse A9M0050 - Replacement Shell

    In case anyone else is looking to do this, note that not all M0100 mice will work. Of the 5 M0100 mice I had, only one had compatible insides. First, it must be the version with 2 screws by the cable. I have one M0100 mouse that looks to be a rebadges Apple IIc mouse with a single screw on...

    Massive (filthy) find in South Carolina

    The G3 AIO? I did post about it here: https://tinkerdifferent.com/threads/the-black-mac-no-one-asked-for-powermac-g3-all-in-one-molar.3189/ Yeah, once I get all these machines sorted, I'm going to have to decide which to keep (and which of my existing machines I need to pass along. I will...

    Need solution for HDI-45 to DB-15 connectors for video out

    I was trying to avoid interfering with the PDS slot screws. And giving more space for the potential 3d printed cover. I also don't have a 7100 to see where the cooling vents are. Looking at my 6100, it does appear I could put it closer to the right. I'll adjust my PCB...

    Need solution for HDI-45 to DB-15 connectors for video out

    Yes, I have some 0.52 round header pins on the way, but couldn’t find any 2mm pitch longer headers (probably will need ~12mm length) with round pins. This was just to test the spacing of my HDI-45 layout in Eagle. Although I did confirm all the pins fit very snug and were making secure...

    Need solution for HDI-45 to DB-15 connectors for video out

    Yeah, that diagram was for the PCB pins on the board, not the external connector. The connector is actually less than 2mm between pins. I just did that real quick. The pins on the adapter appear to be ~0.6mm round pins. The pins I used were 0.5 square pins. I did not. The pins were such a...

    Need solution for HDI-45 to DB-15 connectors for video out

    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...

    Need solution for HDI-45 to DB-15 connectors for video out

    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...

    Need solution for HDI-45 to DB-15 connectors for video out

    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...

    Need solution for HDI-45 to DB-15 connectors for video out

    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...

    Need solution for HDI-45 to DB-15 connectors for video out

    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...

    Need solution for HDI-45 to DB-15 connectors for video out

    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...

    Need solution for HDI-45 to DB-15 connectors for video out

    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...

    16 MB RAM SIMM for Mac IIfx

    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!

    Massive (filthy) find in South Carolina

    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...

    Need solution for HDI-45 to DB-15 connectors for video out

    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...

    Need solution for HDI-45 to DB-15 connectors for video out

    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.
