    Unable to access the Wiki

    Same now (I just joined, so not sure if it was changed in the mean time). Perhaps if this is the plan moving forward, someone could change the link in the Wiki Forum. It currently says (and I tried it several times and thought the Wiki must just be down.. It was a while later that I realized that the wiki is up, as long as I don't use that link. ) : 68kMLA Wiki Follow0 The creation and maintenance of the 68kMLA's information repository. http://68kmla.org/wiki/
  3. Well, after my experience with my Mac Classic, where I opened it up to check the battery and found CAP corrosion, I knew it was time to check the IIsi. As I mentioned in the other thread, there was some damage on one of the pads under a CAP on the Classic, but it appears to have cleaned up nicely and I was still able to solder on the new CAP and it is working. Whew. So I got nervous about my IIsi. That, and the pics/videos of exploding batteries had me freaked out. So I opened it up. Good news is that the battery didn't explode and doesn't even look to have leaked. I didn't do too close a look at the CAPs. The initial visual of what I could see looked OK. But that was the same with my Classic till I really looked. I decided to hook up and plug in the IIsi and see what it would do. Good news is that it booted up all the way to the desktop. So that is good. I did notice there is no sound, which I believe is/could be a sign of CAP issues. So I ordered another CAP kit which is on it's way. Man, the IIsi has a LOT of CAPs!!! Hopefully with a good cleaning and some new CAPs, it will be happy and with sound. Note: I ordered a kit for the motherboard. I know there can be issues with CAPs on (some? Sony?) PSUs, so I need to check that when I take it apart again and see if I need to replace some CAPs there too. Also, it has 17M RAM. Right now, I am thinking that is probably plenty for him??? I know he can take more, but not sure if that is worth it. I am considering a 50mhz crystal to get him to 25mhz. The boot up time seems slow, but I think that is mostly the SCSI hard drive and System 7.5.3 (and those extensions)... Also, I noticed that the IIsi has the extra reverse power plug for attaching a monitor, but my monitor has a standard plug on him, hardwired. I'm sure there are probably adapters for that if I want to do that. (I know I can just plug them both in and/or use a power strip, but.. ) Anyway, after my Classic seemingly successful repair, I am more confidant. I hadn't used the hot air side of my hot air/solder station before and that worked great to remove the CAPs on the Classic. So, fingers crossed. There is something about the 8Mhz B/W Classic that I really like and I use him more. But my IIsi does have ethernet, which is a huge plus. (I just realized I hadn't tested the IIsi floppy drive.. Need to do that also...)

    SE/30 PDS Adapter Epic Blunder

    I don't have an SE/30, much less one with an accelerator so this thread doesn't apply to me... That said, reading this thread makes me very happy!! Great work!!!! Even tho it doesn't apply to me and.... <thinks about the IIsi I am getting ready to order CAPs for...> ...um.... Well, if it applies to me or not, still great work and a great thread! I love reading about successful repairs and the finding and acquisition of those chips!!! Congrats...

    Best way to open Mac Classic

    Yes, strange times indeed.... Hopefully it has 2M. That's what mine had. I have heard the only thing to look for memory wise is that it has at least 2M. If it has 1M, then it doesn't have the RAM expansion card (where you can add the other 2M) and those are hard to find by themselves. Luckily, 30 pin SIMMs aren't too hard to find nowadays... Good luck! Also, I have the hardest time opening mine. It REALLY doesn't want to let go at the top. Eventually it does, but .. it doesn't make it easy.

    Best way to open Mac Classic

    I just recapped my Classic. I wasn't seeing the Simasimac, but when I opened my Classic to check my battery (which was fine, but I still replaced it), I thought I saw some cap leakage. When I removed the caps, one of them had some significant corrosion under it that I hadn't noticed before, and it had damaged the pad a bit. Luckily not so much that it didn't work after recapping. The other item I had was that after recapping, the Classic was acting up a bit, so I really cleaned the motherboard well. After that, it's been stable. (knocking on wood) So for now, I'd recommend cleaning the board as much as you can. I just did the logic board also, not the analog one (yet). Good luck!
