    Re-cap gone wrong.

    The LC form factor power supplies nearly all need recapping, so that may be your next project, in order to restore proper voltage to the HD. For the lifted pad issue, you might get lucky and be able to easily trace the via to a spot that would allow you to solder on a jumper wire. If not, repairs can sometimes be accomplished, but they are not easy. Congrats on getting your machine. Hope the repairs go well.
  2. I never did either, my brother was the one in our family that did electronics work (built circuits, soldered things up, etc.) Rather late in life, I started my soldering experience with a cheap soldering iron. I began joining wires together and with practice got used to how it heated up, how the solder reacted and how the different types and thicknesses of wires would react. Later on I needed to do more and started practicing desoldering and soldering on old circuit boards (they are literally everywhere). When I felt ready, I recapped an SE/30 that was dead, but revived by washing the motherboard. I brought it back to life and after that I was hooked. Not that all my attempts worked, which is why I will never be one of those folks that works on other peoples boards. There were a few boards where I totally failed and fortunately I was able to send one off to be fixed (I had both someone to send it to and the funds to have it done at that time) and another one, a classic, I pulled too many pads during desoldering and had to buy another board. But you have to try, its SO rewarding when you hear that startup bong on one that you brought back to life. Its not going to happen overnight, but you can make it happen, even if you don't have the talent that some of these folks do.

    Studio Display m7613

    All that I found was this... https://archive.org/details/apple-manual-studio-15-dvi It doesn't have a part number for the LCD, but it does list the specifications. If you are taking it apart anyway, it may have a part number on the panel, or you could use the specs and internal connector information to find something compatible?
  4. If these were transported at all (shipped, packaged, carried) you might want to check the video connector (and other connectors) to make sure it is plugged in before you declare no-joy on the video. I have gotten a few compact macs that were disconnected at the CRT and simply making sure it was properly plugged in 'restored' the video. Obviously it won't fix the one with the checkerboard pattern.

    Another way to transfer programs to a classic Mac

    I'm sure that I see one of these in my future!

    4 iMacs & 1 eMac

    I had one that had the 'red shift' screen issue. At first it was like having a plasma display and kinda cool, but that feeling went away pretty quickly, when it was your main work machine. I got mine working normally again, but I could never trust that the issue wouldn't come back and I really didn't like working inside it, so I sold it. That is one that I regret losing, especially since I had bought it new, One of the coolest Macs ever, IMO. Enjoy, sixsevenco ... and color me envious.

    512K Disappointment

    This post was rather timely, as I've noted before, I was working on a 512 of my own and today I was working on the keyboard (the 'u' key did not work) and I used some of this post as a guide. I pulled the key, desoldered and disassembled the switch and finding corrosion, removed some by scraping with a pin and then put it into a small bowl of vinegar, followed by a water/baking soda mix, then water, then contact cleaner. Testing the reassembled switch confirmed it was working, so I reattached it and have a fully functional keyboard. Congrats on getting your 512k with SCSI up and running as well.

    512K Disappointment

    Yep, that did it. It still amazes me that a perfectly solid appearing solder joint can be bad. Thanks for the assist and sorry that your MacSnap didn't turn out the way you wanted.
  9. I've retrobrited a number of items and there are two that I've shied away from and one is my 5200. If those clips on the side (the ones hiding the screws) don't shatter when you pry them out, other parts and clips will crack and break - even under minor pressure. You have a nice all in one bridge machine, recap it, max it out with goodies and enjoy! Be extra careful with the vent on top (and sides), I had a similar vent on top of a 1710AV that I lightly pressed on and it just crumbled to pieces. Since the design is the same on these, I have always been careful with my 5260.

    512K Disappointment

    I just picked up a 512k with one of these as well, but it also came with the 2MB board. Mine starts with a normal startup bong, then shows this exact screen pattern https://68kmla.org/forums/uploads/monthly_2018_12/IMG_0152.JPG.ce426fee7e7481d7f9dbf7771c053972.JPG (the link is from another post about SE/30 Micron card issues, but shows the issue perfectly) I thought that it was an issue with the SN74L538 chip [as mentioned in the Dead Mac Scrolls], so I swapped in another of those and the issue is still there. Pressing on the analog board, about midway down, using appropriate care, will show the desktop, arrow cursor and flashing disk icon, so I think there is a reasonably easy fix, I'm just not sure where to go next. I guess that we both have work to do to get these working correctly. Good luck with yours.

    So I picked up some Macs today...

    That is a nice haul, I have a soft spot for the Tandy laptops (too much time spent at the local Radio Shack, I guess), so I'm a bit envious. The boxed software and all those odds and ends are nice too - congrats!

    Help resurrecting a 7500/100

    So does any PCI-SATA, or PCI-ATA card work or does it need to be a Mac specific one? I'm looking at doing the same with a 7600 and 7300.

    LC and Classic II

    Sounds like a nice consolation prize. Good luck with the recap project.

    My powerbook 170

    I'm impressed with all the extras, and in such excellent condition! Very nice!

    Mac Plus M0100 mouse only moves horizontally

    I have this issue as well, but the vertical works and the horizontal does not. Like clpo13, the issue is seen on a Mac Plus that otherwise works normally. Since I have multiple machines and mice, I verified that two, separate, known working mice demonstrated this same behavior on the machine in question, so it is definitely a problem with the Mac and not the mouse. All I found in the dead Mac Scrolls were fixes for mice issues. Im looking through Inside Macintosh and it gives a place to start looking (hardware, III-29) but if anyone has encountered this problem already and has a fix, let us know.
